Great Dungeon of All Timelines

Possible Shortpaign Idea: Great Dungeon of All Timelines (or GDoAT)
LORE STUFF ------------------------------------------------
The GDoAT (probably has an actual name that's less of a mouthful) pulls random souls to live inside of it, giving them effectively a new chance at life. It sort of "clones" their spirit, meaning that their original timeline isn't interrupted, and it either powers up or powers down those that come into it - a god that was just pulled in is equivalent to an office worker that was just pulled in.

Inside the Dungeon, there's multiple floors, which one can travel to through teleportation circles found in just about every single city. There's 6 floors in total, each of which has its own sort of "biome" of sort. Settlements are generally found on each floor, and each floor is a sort of "default" for various figures; the first floor might be the "default" for people from medieval time periods, while second might be for "villainous" figures, etc. (Haven't figured that out yet) People who first come in enter a sort of "tutorial" place, which has the Guardian Spirit of the Dungeon show them a bit of the ropes, though not everything.

On each floor, mini-dungeons pop up all the time, which contain secrets of the Dungeon, as well as summoned spirits of much more monstrous/malicious natures; you might see past foes pop up, like the dreaded Crystal Guardian, or legendary beasts like Cerberus. Most spirits that are summoned to this world will jump at the chance to conquer these mini-dungeons, for the secrets that lie within are usually worth dying for.

It is believed that the Guardian Spirit of the Dungeon is the sort of "deity" of this world, and that whomever discovered the ritual that made it will be able to become a deity themselves, letting them rule over the populace, as well as pull anyone they want from any timeline into the Dungeon.

MECHANICAL STUFF -----------------------------------------
You guys will be beginning at 5th level, and I expect the campaign to end at 11th or 12th level (with a final boss fight at that level).

Thematically, any char concept can work: you can be a sci-fi robot if you like, or you can be very medieval, whatever you like. Any race, class, subclass, etc. is fine (provided it's balanced, of course). Go ahead and make a fucking Isekai protagonist if you want.

You're free to make a new original char, use a past char, or even interpret figures from culture if you want; if you wanna be the Hollow Knight, you can, or if you wanna go George Washington, you can. If you're interpreting figures from culture, I'll let you do Fate-style, where you can change up and interpret them in weird ways, like how that computer guy, Babbage, had a fucking mech suit.

Each character will get a sort of MOBA passive and ultimate. Passive will (usually) be always on, and the ultimate will typically be a 1/rest ability. Some ultimates might not be, like they might be a second passive, or they'll be like an Elise thing, where it's a form change without a cooldown. Some might also be more Corki-esque, where they're just an ability with a shorter cooldown, or more uses per rest.
-------------------------------------------------- FLOORS ---------------------------------------------------
Floor 0: The Tutorial. You guys might experience this or not, we'll see. It's basically a very blank place where everything is made out of bluish-green light outlines, and the Guardian Spirit is there.

Floor 1: The Wild Woodlands. The center of this place is akin to a generic medieval town in grassy plains, but the deeper you get out, the more that plants sort of rule over shit - eventually, it's just jungle that is so incredibly thick with vines and vegetation that you can't easily get through without burning a lot of shit down. Most people start here, provided they don't meet the conditions of other starting areas.

Floor 2: The Misty Mountains. The center of this place is filled with large mountains, each one connected to by bridges. Some settlements, dungeons, etc. are built on top of the mountains and plateaus, while others are inside of the great rocks. The further out you go, the more spread out the mountains are, to the point that in the furthest reaches, some towns are just straight-up built *on* the bridges. This is the starting place for people that are either used to dwelling underground (or an equivalent, like Hades), and those that are used to the skies, such as deities of storms.

Floor 3: The Corrupt City. Sometimes called the "city of smoke and lamps", this place is just a giant civilization that is made out of architecture from all parts of history - you might find a 1920s casino right next to a robot repair shop and an entrance to the Labyrinth here. The skies usually have smog covering them, meaning that most of the light comes not from the sun, but from streetlights. The further out you go from the center, the more dense that the buildings get, eventually having it so that structures fuse together; you might enter a bathroom in a supermarket and find that it leads to a Roman coliseum. This is the starting place for figures that are associated heavily with civilization (such as politicians), as well as most criminals.

Floor 4: The Glitched Graves. A world that doesn't follow the rules of reality quite as precisely, this floor is made out of digital laws and creations personified through the magic of the Dungeon. The center appears to be a Vegas-esque city made out of game pieces with various videogame and board game symbols, but the further you get, the closer that it gets to just being 100% digital, and the more "glitches" that appear - a "glitch" can include things not functioning as properly, or they might be laws of reality that are changed for a duration. This is the starting place for figures that were fictional and created in digital mediums, such as video games - although, some movies will also count. It can also include beings associated with games, such as mafia men known for gambling, or deities of games and fun.

Floor 5: The Frozen Fields. The center of this floor has a great kingdom made entirely out of true ice, and the grounds are always covered in snow - however, the further you go out, the more that the "cold" manifests, as the auroras that constantly streak across the dark skies seep into your mind, and intensify your negative feelings. At the very ends of this place, there are hundreds of red eyes glowing past a wall of darkness, which occasionally form auroras from their pupils - though, almost nobody knows of this, as most are consumed by their emotions before they reach it. This is the starting place for those who are famous for being flawed, such as "villainous" characters, or many Greek "tragic" heroes.

Floor 6: The Unknown. The center of this place has a small town, which appears to be in the style of the Wild Woodlands - however, outside of its walls, there's just endless darkness. If you step into the darkness, you--as well as anyone else touching you--will be transported to a random mini-dungeon in any of the floors - this can rarely include ones found on floor 0, but in most cases, the Guardian Spirit will just banish you back to floor 6's town if you do, unless you promise to help her in teaching some new spirits.
-------------------------------------------------- GUILDS ---------------------------------------------------
Being in a guild does *not* restrict you to the specific floor of its headquarters (unless of course the guild says it does); rather, that's just where the HQ is.
FLOOR 0: literally none. Guardian Spirit might temporarily make one for a test, but it won't last.

FLOOR 1: The Greenshields, owned by Quetzalcoatl, the Aztec serpent deity. They are a pretty generic group for the most part, focused on employing adventurers to defend the Woodlands from some horrors that crawl out of the mini-dungeons, or just "spawn" out of nothing. Also hosts a festival annually, with a lot of alcohol made from some grapes found in the deepest jungles, which its members have to go collect.
STARTING ROSTER: Beroot, Hollow Knight (Pure), Artoria (Queen Arthur), Dionysus

FLOOR 2: The Sky Brigade, owned by Zeus except he's a woman for some reason. They ride on stormclouds and such, and are primarily concerned with handling natural disasters, rogue creatures in the skies that would seek to destroy bridges (like hostile dragons), and sometimes fighting other versions of Zeus that seem to pop up a lot.
STARTING ROSTER: Jaegar, Apollo, Hornet, Mannequin

The Zeus Brigade. It's like the Sky Brigade, except it's just formed of 20 different versions of Zeus, including him as a goose. You can't join unless you're a Zeus.
STARTING ROSTER: Zeus, Zeus, Zeus, Zeus, Jupiter

FLOOR 3: The Cult of the Grimmchild, owned by a partnership between Troupe Master Grimm and Nightmare King Grimm, as the two have separated into different entities inside of the Dungeon. They're mainly concerned with creating more "Grimmchildren", which will eventually grow up to create more Grimms - the Dungeon means that they won't actually need to die to do so, so they're more so concerned with making a lot of them. Members can either become Grimmchildren themselves, or just be exclusively people that spread their message - sometimes forcefully. They might also just be like favored mercenaries, which take jobs for the cult, but nothing more.
STARTING ROSTER: Umarin, Gilles de Rais, Stone Mask of the Vampires, Count Nebulae

FLOOR 4: The Dice Delvers, owned by Mister King Dice. They are mainly a gambling industry of sorts, but they also seek to understand why it is that the glitches of their floor happens - many of their members will work in their casinos (both on floor 4 and floor 3) at night, but during the day, will head out to the further reaches of floor 4.
STARTING ROSTER: Zote the knight of great reknown, Scazz (Original), Jin of the Thousand Blades, Gashadokuro

FLOOR 5: The Torchbearing Blades, owned by Ra. They are concerned with trying to fight back the auroras that spread negative emotions, and are sort of like the 'paladins' of the floor. Also, they want to spread a lot of light and burn some things sometimes, but it's more like a "burning man festival" rather than "actual fucking arson".
STARTING ROSTER: Harox, Umikk One-Arm, Jeanne D'Arc, Dhalsim

FLOOR 6: also none. There's little reason to really form any here, as it's basically just where parties go out to find a random dungeon, without having any fear.
ROSTER: Plot Bonesman. He's just kind of there.
