Editing Imperial Purgators (section)

===Triassos===
Triassos is an old world orbiting and old star; it is a damp, sweltering world, networked with small seas where the bulk of the land consists of vast expanses of undulating hills with slow, silt choked rivers wending lazily between them, and all overgrown with verdant decadent green canopy.

Upon the few mountains, higher, where the air is cooler, away from the endless decaying tentacles of vegetation the hive cities perch. The only mountain not surmounted by a hive city is the last great volcano thrown up by the planet's listless core, a great cone of basalt that who'se sides still smoke and ooze lava and upon which the chapter has established its fortress. The hives are where the people live, occasionally sending out drilling teams to extract the planet's deposits of promethium, sometimes drawing the attention of feral orks spawned from some long-passed WAAAAGH!; the larger infestations require the attention of the Purgators to be cleansed before the promethium extraction can resume. 

The n'Tabi were found centuries after the planet's colonization. Where the hives were built up to avoid the jungle the monstrous xenos had gone down, living beneath the surface. As the hives grew up, they also grew down, acids and chemical wastes seeping into the hearts of the mountains, finally into the lairs of the n'Tabi. Their blind wormlike heads could sense the movements of air currents and catch the softest vibrations and so they struck at the sumps first climbing out of the depths and slaughtering gangers. When they reached the first arbiter wall the Telepathica sent for help, and the Chapter arrived. 250 years of fighting beneath the skin of the world. 250 years of flame filled tunnels, melted earthen bunkers and gene-seed lost to cave-ins both intentional and not. After driving them back to their last great city, the Purgators strapped engines to a great adamantine pillar and punched it straight through the crust, boring a hole that would flood their underground city with magma, and give rise to the great volcano that would serve as both the tombstone of the species, and the fortress monastery of the chapter. Atop the pillar are six words, "Suffer Not The Xeno To Live".

The n'Tabi were not buried- they were cremated.
