Ryza

Ryza once fuelled the larger Imperial war effort, but since Waaagh! Grax descended, those days are long past. Now Ryza’s Tech-Priests turn every second of the planet’s industry to the business of survival alone. The greenskins made planetfall upon Ryza in the hundreds of billions. That number soars and dives with every hour, defying even the ability of the Magi Logis to quantify it. The Imperium has met the greenskin assault with over twenty Astra Militarum regiments fighting alongside Skitarii macroclades, Legio Cybernetica war cohorts, even Titan Legions, yet the Orks attack afresh with every new dawn. The Tech Priests of Ryza have turned to more inventive measures: virus bombs rain down across the Obduras continent, laying low lesser greenskins by the million as hermetically sealed Kastelan Robot Maniples thump phosphor rounds into those Orks tough enough to survive. Above the polar metropolises, Ork fighter craft are harried by Onagers modified to crawl up the sheer hive walls. Salvation teams reclaim fallen god-machines, piecing them back together with ritual and supplicant incense even as Ork mekaniaks resurrect their Gargants with little more than welding torches and foul language. Upon Ryza it is not attrition that will carry the day, but invention – a quality the Adeptus Mechanicus considers all but heretical.
