Sigma-Ulstari is an Imperial Forge World and the only Warden Planet that lies within the Cordon Impenetra, which borders the Ork Empire of Octarius.[1]


Overview

Some three-quarters of its surface is covered in kilometers-deep oceans of toxic waste. These are so corrosive, that the world's Magi have determined that draining the oceans, to make room for additional structures, was too inefficient a task to countenance. As a result, Sigma-Ulstari's forgefanes, mechashrines and foundries have been built into colossal tower-factorums. These structures resemble the spines of an armored animal and many are so high, that they scratch the world's upper atmosphere. Each bristles with thrice-blessed defensive-weapon stations, and squadron after squadron of Adeptus Mechanicus Frigates, Cruisers, Battleships, Factory Ships and Forge Tenders, dock there at any given time.[1]

History

Since the Octarius War began, Sigma-Ulstari has suffered no fewer than three full-blown invasions from both the Orks and Tyranids. Such is the Sigma-Ulstari's output of tanks, munitions and weapons of all kinds, that the Imperium cannot allow it to fall, however. As a result, the Warden Planet has survived each invasion, thanks in no small part to the massive Imperial reinforcements, that have been sent to defend it. While the cataclysmic Xenos invasions failed, though, they have left millions of Orks and Tyranids alike stranded on Sigma-Ulstari' tower-factorums. The Xenos now fight for survival against Adeptus Mechanicus, Adepta Sororitas and Space Marine kill teams sent to destroy them. The Astra Militarum is also present, with the Tempestus Scions and the Death Korps of Krieg being amongst its forces. Despite their purging efforts, however, those who defend Sigma-Ulstari, believe it is only a matter of time before the next all-out invasion begins.[1]

During the later stages of the Octarius War the final Tyranid and Ork push on Sigma-Ulstari came. Despite its formidable defenses under Fabricator-General Einrekh Phlagustok, the world nearly fell and was saved only thanks to the arrival of an Indomitus Crusade taskforce under High Marshal Helbrecht. The situation on the world now is stable but perilous.[2]
