Dolumar IV

Dolumar IV is a Fire Warrior campaign world in Ultima Segmentum, the Imperial colony Governor Meyloch Severus sold to the daemon Tarkh'ax. This low-confidence pin is that T'au/Chaos disaster, not a sept world.

Severus abducted Ethereal Ko'vash to bait a war, spilled enough blood to crack a millennial prison, and turned the Enduring Blade into a slaughterhouse. Kais, Battlefleet Ultima Primus, and the T'au recovery force killed the plot; the Navy then declared the planet too rotten to keep and issued Exterminatus.

Dolumar IV still matters as the Fire Warrior board. Unofficial summaries keep the Ultima parent and do not mash this dead rock with T'au septs or with Damocles Gulf treaty worlds.
