Damnos

Damnos is an ice mining world in the Damnos System of the Vidar Sector, the Ultramarines' Necron campaign that first broke Cato Sicarius and later brought Calgar back for a second war. This pin is that tomb-under-the-ice, not a random Ultima snowball.

The Undying rose, Kellenport burned, and Agrippan died covering the evacuation that Imperial histories still call the Fall of Damnos. Twenty-five years later Calgar returned with Guard and Deathwatch, cracked the Baleful Necropolis, and Sicarius spent a vortex grenade on a transcendent C'tan. The tombs stopped standing back up.

Damnos still matters as the named Ultramarines/Necron board. Unofficial summaries keep the damnos-system parent and do not merge this world with Antax the neighbouring forge.
