Bromoch

Bromoch is an Imperial hive world whose surface was once covered by vast oceans teeming with life. In 765.M41 a mechanised tomb complex awoke beneath it, draining its seas within days and leaving half the world a quagmire of salt mud and rotting biomatter, from which legions of Necron warriors marched on the hive cities. The Iron Hands of Clan Raukaan, accompanied by Kardan Stronos, covered the evacuation of Hive Primus and destroyed the tomb complex, and the planet fell into a new dark age as its orbital silos detonated. Its position is not recorded.
