The Adeptus Administratum and the Imperial Estate, Chancellery, Treasury, and Exchequer
The Sectors of the Tri-Sector are blessed with shared borders, with barely anything between them save empty space and whorls of gas.  Of course, navigation is somewhat tricky in the Tri-Sector, and moreso the closer one goes to the Terminus Shock Warp Storms.  The Adeptus Administratum and offices of money and tax in the region share some infrastructure and assets, although the number isn’t great.  However, the crucial role of minting the Imperial currencies and establishing the inter-planetary exchange rates of local currencies is carried out by the Imperial Mint in the Paros system in the Naxos Sector.
There is no one Exchequer for the entire Greater Tri-Sector.  There is an Exchequer for each of the Sectors of the Tri-Sector.  Each Exchequer is managed by the Adeptus Administratum and its appointed Lords, namely appointees of the Lord Sector.  The Exchequer is responsible for tabulating Imperial taxes, revenues from loan repayments, and other sources of money and assets that flow into the Imperium outside of the Tithe.  The Imperial Tithe, by contrast, is controlled exclusively by the Departmento Exacta, outside the jurisdiction of the Exchequer.
The Exchequer answers to the Treasury, which hypothetically has larger authority.  The Tri-Sector Treasury, formally known as the Pursary of the Estate Imperium, is little more than the records department of the Administratum’s financial transactions.  The physical storage of money and fungible assets is controlled individually by Imperial Commanders and System Overlords for their own jurisdictions.  The Exchequer for the Naxos Sector is also located on Paros with the Mint for convenience, while the other two are located on the planets Maskos (for Cloudburst) and Glendol VI (for Drumnos).

The Chancellery of the Tri-Sector is a role unique to the region, and holds the vital responsibility of coordination of the reports, surveys, and official documents that pertain to more than one Imperial territory within.  The Greater Tri-Sector, consisting of the Drumnos, Naxos, and Cloudburst Sectors, Cloudburst Circuit, and the slivers of habitable space in the nearer reaches of the Oldlight Exo-zone, has many bodies and parties that cross from one region to another.  This includes Rogue Traders, the Questio Logisticus, the Imperial Fleet, the Space Marines, and of course the Adeptus Mechanicus, among many others.  Keeping track of all the reports and movements of people and ships across their many boundaries would be quite beyond anything less than a specialized body of the Adeptus Terra, and the Chancellery holds the role.  Its agents are all Adepts, and travel around the region aboard any available ships, collecting copies of the reports that those vessels and any others nearby may file.  The Captains of these ships typically only barely tolerate the Chancellery’s agents, seeing them as only marginally better than domestic spies, but the penalty for refusing passage for an agent of the Adeptus Terra is typically life in prison for any offender, and so the Chancellery’s Adepts usually travel unobstructed.
The reports and files collected by the Chancellery are compiled every few years in the Sector Command Fortress on Sardineos in the Drumnos Sector’s capital.  These files are usually then indexed and forgotten by Adepts of the Estate Imperium.  On the rare future occasion that the reports are needed again, those who need them can request the aid of curators and Adepts who spend months at a time combing through the data looms and gigastacks of the Chancellery on Sardineos.

The payment of Imperial officials and crews of ships is carried out by Subsector and Sector commands, not the Exchequer.  The Adepts and sailors of the Imperium are simply too far-flung to pay through a central authority.  However, the Exchequer of each Sector does hold the responsibility of ensuring that any Imperial Navy or Adeptus’s fleet assets that are requisitioned for a Crusade or a Rogue Trader’s expeditions are paid properly.  A mutiny among the crewers of a voidship is devastating, and even the Imperium, with its staggering inefficiency, must take steps to prevent them.


The Adeptus Administratum of the Greater Tri-Sector has no one lord.  Each Sector has its own Lord Sector, each system or world has its own Imperial Commander or System Overlord, and the two local Astartes Chapters do not govern their own systems.
The title of Supreme Prefect is highly unpopular in the Cloudburst Sector; perhaps uniquely among the inhabited Sectors, there is not one System Overlord nor Imperial Commander who uses it.  In practice, the Imperial Commanders of major worlds are effectively Supreme Prefects if that world is governed by the Adeptus Administratum, but there is historical animus and superstition against the title in Cloudburst that has not been overcome.


The Gargantuan
The Fortress-Monastery of the Blue Daggers is a massive, hollowed-out asteroid.  Named the Gargantuan, the structure dates to before the Chapter as Founded.  Originally, the metal-rich asteroid was earmarked for void mining by the Adeptus Mechanicus.  Before Solstice had a single permanent base, before the Blue Daggers Chapter existed, before any being of the galaxy even knew the Glasians exist, Asteroid ANKS-S 3-4 M-Fe1 fed the forges of Septiim Primus and Secundus with its bountiful iron.  The chunk of rock, a grey thing covered in thin dust and now aglow with lights, had attracted the eye of Adeptus Mechanicus surveyors for its metallic richness.
During mining, the rock proved remarkably stable and resilient to the effects of mining, even in the face of the use of the Maskos mining machines.  The Adeptus Mechanicus was able to extract tens of thousands of tons of iron, oxygen, silicon, and manganese from the asteroid before the Glasians arrived.  After they did, and more importantly after they returned, the Adeptus Mechanicus agreed to cede the station to the Adeptus Astartes to serve as a Fortress Monastery.  There was some contention among the Techpriests responsible for operating the mines, but it was quickly shushed by the Techpriesthood higher-ups, who recognized the colossal honor that was about to fall upon the humble Mechanicus station.

Today, after centuries of non-stop, frenzied construction by the finest voidsmiths in the entire Cloudburst Sector, the Gargantuan had gone from a dead chunk of stone and ore to a bulwark of combat might.  Its thick, rocky shell remains in place, the better to hold atmosphere, but its interior surfaces are braced with skeletal spurs of adamantium, ceramite, and plasteel that can withstand torpedo fire.  Indeed, between the rock layer outside, the hull material underneath it, and the reinforced steel and plastic bulkheads under that, the Gargantuan can withstand cannonade for months from anything smaller than a Gloriana super battleship.  Its outer weapons are typical for an Imperial space station of its size, save its main battery: a Triple-Linked Nova Cannon, one able to hull an Ark Mechanicus with one hit or tear the outer hull and armor from a Glasian Control Cylinder with a blow from all three barrels.  Its sheer size boggles the mind on newly-initiated serfs; to look upon the great guns is to look upon death itself, held in the clenched fist of the Emperor’s gene-sons.
Beyond the Nova Cannon battery, the station has other defenses.  The Gargantuan is smaller than a Ramilies star fort or the massive Phalanx, but has void shields comparable to the Ramilies in durability.  However, its ability to repulse a fighter attack would be far smaller than one of those facilities, thanks to its small hangars.  While the final construction of the facility is still centuries away, the Gargantuan is already more than able to defend itself from any two known Glasian vessels.  However, Lord Ranult Arden is a believer in forward planning, and has plans to drag the rubble left over after Maskos machine mining of the asteroid out onto its exterior to form another layer of armor, allowing even more expansion inside and hardening its defenses yet further.

The station’s extant portions are more than large enough to house multiple Companies of the Chapter concurrently, and are nearly large enough to house the whole Chapter.  Since the Chapter has not been assembled to the last Brother since its inception, thanks to its extensive patrol duties and Deathwatch commitments, that has not been a problem.  However, the construction continues apace.  Within the Gargantuan, there are many delineated chambers.  The following is a non-exhaustive list of them.

External Wards
The number of external weapons of the station is higher than it appears.  The weaponry that protects the Gargantuan is sometimes concealed behind marring on the surface that appears, to the untrained eye, to be common impact scarring, uneroded by the vacuum of space.  Among these craters are cupolas for laser weapons, and even launch tubes for torpedoes and plasma warhead missiles.
Other weapons are not so concealed.  Macro-cannons and laser weapon batteries jut obviously and intimidatingly from the surface of the asteroid, surrounded by blackened slag from the means used to bore the initial mine shafts into it long ago before the Maskos machines could take over.  The symbol of the Blue Daggers appears nowhere on the exterior save for a single, colossal plate that covers the primary docking cradle.  The cradle is large enough to accommodate the forward half of the Sharp Edge, the flagship of the Chapter.  When the Sharp Edge is not present, the cradle can accommodate any smaller vessel of the Chapter, or several Escorts.  The interior of the cradle holds over fifty multilaser defense turrets to shoot down attempted boarders or torpedoes that are fired into the massive opening.

The other external structures of the Gargantuan are an Astropathic temple on a stalk that extends above the surface, covered in wards and sigils of protection from the depredations of the Warp; a single docking tube for docking with vessels larger than a Battle Barge that has never been used, and a handful of stationkeeping systems that use plasmic funnel engines to move the massive station between orbital slots.

The Docks
Inside the Gargantuan, entry is tightly controlled.  The station is so far from any habitable bodies that it has no tether nor spire to connect it to other Imperial worlds or moons, and so the only way in or out is by the docking tube, the cradle, or the teleportorium.  As a natural result, security is focused around intruder control in those three places.  The docks, those that line the cradle especially, are fortresses in their own right, with multiple-meter-thick slabs of enriched alloy plating separating every compartment.  The docking cradle itself is massive, its interior bristles with gun turrets, and great cranes and gantries cling to the walls and bulkheads with paper prayer seals of the Adeptus Mechanicus hanging from them.  Chanting Tech-Adepts in service to the Chapter maintain the great machine, but it is the Techmarines of the Chapter that hold ultimate authority over the place.  Under the Master of the Gargantuan, Jeremy Haskell, the docks take in the supplies and manpower needed to uphold the station’s function.

The Tunnels
While the Gargantuan today is a Space Marine Chapter Fortress Monastery, it began its use to humankind as an Adeptus Mechanicus mining facility.  The Mechanicus still has a strong presence there, both as the ones who perform the bulk of the maintenance on the station and as a team of miners that are continuing to operate Maskos machines that expand its interior space even centuries later.  The mining tunnels left in the wake of the Maskos machines were quickly taken over by the newly-established Blue Daggers Chapter after the Second Glasian Migration.  Smaller side tunnels were quickly dug out, following structural and tactical priorities instead of chasing veins of ore.  Other galleries were radically expanded, allowing for great assemblies of training Astartes, the storage of food and ammunition, and the installation of colossal plasma reactors to power it all.  This section of the station had its essentials placed before any other components, to allow the crippled Exigent Task Unit Cloudburst to transform into a proper Chapter.
The Founding of the Chapter was an unusual one, with the establishment of the logistics chains and lines of command that fell outside those of the previous twenty-six Foundings.  The tunnels that span the Gargantuan reflect the unusual nature of its origins, with bare rock and deep shadows hanging in ever corridor.  While the ultimate goal of the Chapter is to turn the facility into something that reflects the grandeur of their gene-line, they have not had the time, nor have the Glasians granted them a reprieve to attempt more respectful decorations.
Most of the interior of the asteroid is made of these tunnels, with no means of navigation save whatever personal electronics the serf crew may be carrying.  The lack of interior markings has led more than one serf to disappear for weeks in the vastness of the tunnels, only to turn up starving in the wrong part of the asteroid.  While no serf has died as far as the Blue Daggers can ascertain, it seems likely to happen as the station grows to fill its host rock.

Armory Exigence
The name of the primary armory of the Chapter has lingered after its titular function long concluded.  The Exigent Task Group Cloudburst, sometimes just called the Task Force, dissolved centuries ago, with the new Chapter rising from its remains.  However, the name of the Armory Exigence has stuck, partly out of respect for those many Space Marines who died in the defense of the Septiim system during the Second Glasian Migration.
The armory is colossal, taking full advantage of the space the huge asteroid allows its occupants to exploit.  While the majority of Space Marines in the Blue Daggers tend to their own weapons as a sacred ritual, reflecting the bond of trust between themselves and the machine spirits of their weapons, not all Marines are able to bring their weapons about at all times, and others yet have not bonded with a weapon to call their own.  Likewise, the arms of the Chapter’s vehicles and ships require the same maintenance and care as their small arms, and the Armory Exigence tends to them all.
Within the vast chamber, like an apse of a church to the Machine God, sit huge steel racks that cross the whole area, with gaps to allow forklifts and loader servitors to cross.  Mechanics and Omnissiah-blessed gunsmiths labor here to maintain and store the arms of the Chapter, especially those that are in some way historically significant to the Blue Daggers.  Combat relics are typically stored in their own chamber, the Armory Necessarius, a place of great sanctity to the Chapter.  Non-combat relics are stored in the Vault, instead.

Garage and Hangar Blocks
The outer regions of the asteroid that became the Gargantuan have been armored by natural stone and crafted alloys to withstand nearly any possible attack, but the fact remains that storing the smallcraft of the Chapter too close to the void while undergoing intensive repair is dangerous.  The storage of fuel and ammunition in a place that is more vulnerable to external weapons fire could render the Gargantuan vulnerable.  Craft that are ready for deployment are stored in blocks of hangars and garages adjacent to the docks, ready to be stored aboard transport ships, but those that are in need of repairs or resupply are held in special chambers deeper in the station.  There, Techmarines can perform rites of repair and maintenance.  Some of the chambers can be vacuum-sealed to test the air-containment of small ships and aircraft, while others have mobile welding frames on moving robotic gantries controlled by Techpriests.
Huge conveyor belts can carry the vehicles and vessels to the appropriate hangars after repairs are finished.  For new units being added to the inventory of the Chapter, the pacification of the Machine Spirits by the senior Techpriests of the Chapter Brotherhood is performed directly in the hangars, with the affixing of prayer seals to new machines to serve.

Armory Necessarius
This armory, by far the smaller of the two primary Space Marine armories on the Gargantuan, is the storage and maintenance armory for the Chapter relics that are combat-ready.  While somewhat lacking in ceremonial weight, with its white walls and blank floor panels, its harsh yellow lighting and its near-complete lack of ornamentation, the Necessarius is still a most sacred place to the Techmarine Brotherhood.  Arming serfs of the Chapter can perform the rites of supplication to the machine spirits of the holiest relics the Chapter can wield, including those that remain from the initial granting of arms and armor from the Founding Chapters and the Exigent Task Group.

In addition to the weapons and relics of the Chapter being split over the two primary Armories, there is another chamber that sits beside the Armory Necessarium, that being the Hall of Armor.  As the name implies, all of the suits of Power Armor, Terminator Armor, and stealth plates for Scouts that are held by the Chapter are held here when not in use.  As the Chapter is desperately expanding, the amount of ‘spare’ armor is quite small, consisting of fewer than fifty Power Armor suits, a hundred Scout Armor suits, and a meager handful of Tactical Dreadnought armor.

Command Chamber Primus
The control hub of the entire Blue Daggers Chapter.  Within this enormous chamber, there is space enough for a hundred Space Marines and their attendants, four hundred Servitors, and the leaders of the Chapter Core.  Great metal stairways, sized for both mortal tread and that of the Emperor’s Angels, lead from the entry floor to new areas above and below.  The central holotank, a feat of technotheology the Adeptus Mechanicus only barely knows how to maintain, is able to process a theoretically unlimited number of input sources for visual projection, and can display any object within four light-hours of the star Septiim.  Using the tank to project the presence of Glasian Control Cylinders every year is the best way the Chapter has found to control the response of the fleets that intercept it, and allows those non-Marines in the room to understand the flurry of intelligence reports.
One platform above the tank is the throne of the Chapter Master.  The extensive cybernetic connection cables of the throne allows the Chapter Master to respond to signals as they pass through the Gargantuan, and to send signals back out without vocalizing them.  The throne can rise above the floor on a mechanical arm, allowing the Chapter Master to move between and among the platforms scattered around the room and oversee his subordinates and serfs as they work.

The main gunnery control of the station is the only major command function of the Gargantuan that is not inside Command Chamber Primus.  It is located intead in a separate area, so that if the station is ever boarded by an overwhelming enemy force, the chance of losing all command and control in the facility to a single errant strike is lessened.

Teleportarium
Because of the remoteness of the Gargantuan, boarding it is challenging even for its masters.  Its orbital path is stable, but it is far enough from any Imperial holding in the Septiim system that reaching it is difficult for ships that lack sufficient fuel supplies.  For this reason, the teleportation option is an attractive one for Marines that are in need of rapid entry to the station.  The Teleportarium of the Gargantuan is massive, easily twice again those installed on typical Battle Barges,  small, faceless carvings and heavily shielded with its own Gellar Field projector.  The Teleportarium is also surrounded by automated guns, programmed to kill any creature with a non-Astartes Warp signature that emerges from the device.
The sheer size of the Teleportarium allows it to make two-way passages over great distances, and even do so from ships that would otherwise be out of range.  However, it has its limits, and it is too far from any Imperial world to teleport people directly to or from them.

The Arbor
This is a place of holiness and solemnity for the Blue Daggers.  When a Battle Brother falls, and his body can be retrieved as well as his progenoid glands, the flesh of the fallen – and any personalized augmetics – are interred here, in gravel-filled boxes that sit behind indestructible polymer shields.  The Arbor can be entered only by living Battle Brothers, as well as mortuary serfs entrusted with the dignified task of preparing the fallen.  This chamber is dark and quiet, with only tiny electronic lights and candles to provide illumination, and small, faceless engravings of Battle Brothers in robes walking endlessly in circles around the top and bottom of the chamber walls.  Notably absent from the room are any sorts of statues, holos, or paintings of former Battle Brothers; the only representations of Blue Daggers in the rooms are either featureless carvings in the walls, or the actual dead.
Mist from censers drifts through the room on the air currents from the recirculators, and individuals from the Chapter are sometimes found among it, gazing silently at the lost, and contemplating the Emperor’s March.

The Training Gantries
Lacking a groundside headquarters, nearly all advanced training of Initiates takes place here, aboard the Gargantuan.  The Intiates who have survived the lengthy psychological, genetic, hypnotic, physical, and academic screenings and trials are hardened young men, ready to receive the organs of the Space Marine.  Upon doing so, the period of acclimation to the new organs is spent here, in gigantic networks of connected stone chambers within the station.  For years, the Initiates are subjected to intense tests of reflexes, daily combat training, marksmanship drills, and teamwork exercises, turning the raw stuff of humanity into the Emperor’s Finest.
The Gantries are more than just training rooms, however.  Some have complex electronics hidden within the walls, allowing the sudden change of a room’s temperature, air pressure, humidity, and other environmental factors.  The Initiates will be tested here in live-fire combat drill for many years as their bodies change to the Blue Dagger template.
Given the heavy focus of the Daggers’ training protocols on the proper use of the bolter, above and beyond all other weapons and even more than most Chapters, the Initiates of the Chapter have the bolter’s usefulness and versatility smashed into their minds day in and day out.  Initiates spend months of their lengthy training inside the forges of the Chapter and in the Armory, being taught every conceivable aspect of their weapon, its maintenance, and its limitations.

However, Initiates are not the only Blue Daggers in the Gantries.  As the name suggests, the Gantries also have elevated stone platforms carved into the rock of the asteroid that hang high above the zones where Initiates sleep and train.  These platforms contain firing ranges for the Battle Brothers who have completed their training and have become true equals in the Chapter.  Here, Brothers can hone their skills or test new weapons without distraction.  Some of these gantries have open sides, allowing the sounds of weapons fire to filter out into the Initiate training areas, giving the new Brothers a hint of what their futures will sound like: lifetimes of righteous killing.
Finally, the Gantries contain extensive sleeping quarters for the Initiates.  The Master of the Recruits is the only member of the Chapter Council who has quarters here, and he oversees the Tenth Company Captain and his Command Squad, who in turn process those Initiates who have completed their training into proper Scouts.

Manufacturing and Forging areas
While nowhere near those of the Chapters of the first three Foundings, the Blue Daggers do have some limited manufacturing capabity in their Fortress Monastery.  The Gargantuan regularly receives shipments of processed metal and chemical goods from Septiim Secundus, and makes use of them for building those supplies of the Chapter that Solstice, Cognomen, and Thimble do not.  Primarily, the Chapter manufactures its own ammunition here, and some limited weapons.  Cognomen builds by far the majority of the Chapter’s Special, Light, and Heavy weapons, but the bolters of the Chapter come from a forge fane on Solstice.
The ammunition made here is pressed, tested, and graded by the arming serfs themselves, rather than by the Tech-brothers, but every single press and chemical blending device is overseen by Adeptus Mechanicus Techpriests that work with the Master of the Tech Brotherhood.  Currently, that role is filled by Peter Alling-Durant, an ancient and well-respected Techmarine.  Master Alling-Durant carefully chooses which of the Techpriests attached to the Chapter is granted the honor and responsibility of overseeing the ammunition assembly lines, and the Techmarines of the Chapter often train alongside them on Cognomen or Mars itself.

The manufacturing and forging areas produce hundreds of thosuands of bolts and other simple ammunition every month, but of course the Blue Daggers do not often use that much ammunition between Migrations.  When the production reaches a surplus, the excess materiel is shipped off to the vessels of the Blue Dagger fleet, to be stored for use in the combat arms of the crew, their Space Marine masters, or the vehicles carried aboard them.  Now that the Chapter is approaching its full strength, the surplus is tapering off, as great volumes of ammunition are used by Brothers honing their skills in the firing ranges of the Training Gantries.

The Vault
As befits those who take upon themselves the burden of protecting the Emperor’s Realm, the Blue Daggers hold some of the items from their storied histories in great reverence.  For arms and armor, the proper means of reverence is deployment to the field, but not all relics are battle-worthy.  Relics that would be useless in battle are held in the Vault, which is overseen by a member of the Council of Masters.  The Master of the Vault has the responsibility of adding and identifying items to the Vault, but also holds partial responsibility for training the tech-cult of the Chapter’s Techmarine Brotherhood.  In this role, the Master helps to impart a healthy respect for history to new Techmarines.
The chamber itself is protected by slabs of solid Adamantium, Ceramite, Plasteel, Rockcrete, and engraved copper, layered one over another, seven meters thick.  The door is a wedge of Ceramite, shaped roughly in a three-dimensional triangle, that is suspened in the air by a contragravitic system powered by the same systems that control the entire Gargantuan life support and artificial gravity system.  In that way, if hostile forces were to board the Gargantuan and attempt to rob the Vault by turning off the plasmic power core, the door would seal shut, and could not be opened again until power were restored.

The Vault is filled with stasis devices and polymer preservation caskets, containing the most sacred relics of the Chapter.  Because of the Chapter’s relative youth, most of the relics are those that were donated to the Chapter during its Founding, usually from one of the five Chapters that lent Brothers, supplies, vehicles, and ships to the Exigent Task Group.  However, there are others, including some that predate all of them: relics of the Ultramarines Chapter from the time of the Great Scouring or even earlier.

The Gallery of the Emperor’s Sons
Deep within the ever-growing maze of tunnels that riddle the huge asteroid, the Gargantuan is able to host growing amounts of chambers and cabins that do not serve an expressly military role.  The space available to them includes places of contemplation, reflection, and study, as well as preparation for the Migrations.  Among them is a hall set aside for the artworks that members of the Chapter make.  Like many other transhuman servants of the Throne, some Brothers have an eye for artwork, and some choose to express their devotion to the Emperor through votive works.
While the Blue Daggers do not practice worship of the Emperor as a deity, they do acknowledge him as the ultimate human and the apex of the thought of Unity.  Many of the artworks crafted by the Brothers of the Blue Daggers are stonecraft, like sculptures and statuary, and are held here in the Gallery, where any may visit if they wish, even the serfs and bondsmen of the Chapter.

The Core Hall
Despite the imposing name, the Core Hall is in fact a place of business.  The Chapter Core, the group of non-transhuman people that the Chapter holds to its service and are responsible for commanding and supplying its workforce, operates here.  In a place more akin to the towering datastacks and endless inkpots of the Adeptus Administratum than the solemn halls of Astartes warriors, the Chapter Core operates the wheels of logistics, arranging skilled replacements for fallen bondsmen and starship crew.  The Core is also responsible for arranging food deliveries to the Gargantuan, and coordinating liaisons with the Imperial Navy, SDF, PDFs, and Adeptus Mechanicus.
In larger, older Chapters, this role is traditionally filled by serfs that serve under the Master of Victualers or Fleetmaster, but the Blue Daggers do not have that luxury thanks to the Chapter’s youth.  However, the arrangement has workd out well enough that Lord Arden does not see the need to change it.
The possibility of working directly for the Chapter as a trusted servant of the Chapter Core is alluring for the people of the Septiim system, who revere the Blue Daggers for their tireless defense of the Septiim Economic Zone.  Thus, competition is fierce for the positions that open in the Core.  The Septiim Tertius Planetary Academy and Technical University provides all candidates for the accounting and logistics jobs, but all others are filled by serfs that select candidates on their masters’ behalf, from recruitment offices on the Economic Zone’s worlds.

Members of the Chapter Core are expected to never be a liability to the Chapter.  Each and every one, young and old, are expected to be able to at least surpass, and ty to exceed, the ordinary bondsmen that crew the Gargantuan and man its weapons and machinery, in terms of combat readiness and physical fitness.
Every person in the Core, including the Commissarial attache, is ultimately responsible to the Master of the Gargantuan, presently Techmarine Jeremy Haskell.

The Master’s Domicile
While the Blue Daggers as a whole are commanded by the Chapter Master, Lord Ranult Arden, and the ships are commanded by the Chapter’s third in command, Lord Gwinnet Eiger, the Gargantuan is not a starship, and falls under the command of Jeremy Haskell.  An ancient and capable Techmarine, he is the third to hold the role after his predecessors died in battles between Migrations against predacious aliens.  Master Haskell’s personal quarters are as bare and spartan as a Techmarine’s quarters are supposed to be, but the chambers beside it fall under a different role.  Inside the adjoining rooms to his personal bedchamber and meditation cell are small electronic forges and materials crafting devices, allowing him to perform meditative and constructive worship of the Machine in privacy.  Master Haskell uses these chambers more than his predecessors ever did, as he finds a certain joy and calm in working with ammunition and arms with his own hands and mechadendrites.  What is known to only him, Master Alling-Durant, and Chapter Master Arden is that the Master’s Domicile also contains the self-destruct device for the Gargantuan: a one hundred eight megaton hydrogen bomb that would turn the entire asteroid into white-hot shrapnel in an instant in the case that he Glasians were on the verge of capturing it.


Energy Control
A somewhat euphemistic name, but an adequate one.  The Energy Core is the heart of the entire station.  The primary thermoplasmic power plant, the backup miniature plasma-fusion core, and the tertiary batteries for emergency life support are all present here, as well the controls for the power grid, the controls for emergency heat containment, and the supervisory station for the ordinary heat sinks needed to control thermal buildup for anything with a power source in deep space.  The vast halls in which the reactor was assembled are smaller than the sum of their components; the original Adeptus Mechanicus miners started with a much smaller power plant and gradually installed more over time.  However, when the time came to turn the unassuming asteroid into a Space Marine Fortress Monastery, the old reactors were carefully removed and sent off to Cognomen, in exchange for the components for a far higher-output single reactor.  Built in place over sever years and placated around the clock by thousands of skilled Techpriests, Tech-Adepts, lay tech-clergy, and Servitors, the Energy Control complex can put out an amount of power not far smaller than that of the primary Plasmic Reactor of a Ramilies-class Star Fortress.

Never has the Gargantuan actually needed that much energy.  Its power plant’s strain came closest to maximum output during the test-firing of its Nova Cannon battery in the buildup to the Seventh Glasian Migration.  As the station’s interior grows and grows, and ever more lights, air recyclers, and sewage treatment systems are needed, the reactor’s output will, naturally, rise accordantly.
Energy Control houses a great temple to the Machine God behind eight-foot-thick lead plates outside the Reactor Room.  Inside the temple, high and vaunted Tech-Priests and Electro-Priesthood cultists guard the massive control cogitators that direct the power of the reactor to wherever it is needed.  When the station’s weapons are firing, Energy Control oversees the process of pouring the motive force back into the capacitors that power them.
