House Mortan is a Knight House of the Imperium.[1]


By the time the ancestors of House Mortan had arrived upon Kimdaria, the mysterious nebula known as the Black Pall that surrounded the planet had grown unexpectedly dense. Fell creatures, already accustomed to the world’s dim light, roamed the ink-black landscapes, and it was only through the skill and dedication of the colonists’ Knights that the beasts were driven back and the first settlements established. For millennia after the Great Crusade, the Black Pall lingered over Kimdaria and its star system – not until late M35 did the impenetrable shroud partially dissipate, letting in a few diffused rays of sunlight and allowing the long-lost planet to be rediscovered by Mankind. What they found was a bleak and ritualistically ordered world, a place where soaring walls separated civilisation from the monster- haunted darkness that lay beyond. From heavy gates the black Knights of House Mortan would regularly emerge, their constant patrols keeping the encroaching predatory behemoths at bay. The towering war machines had become as accustomed to the endless night as the beasts they hunted, the darkness of their home world seeming to cling to them even when standing in the light, and so as to better fight their obscured enemies, the Knights of House Mortan placed a premium upon close combat. It is a tendency that holds to this day.[5a]


House Mortan stayed loyal to the Emperor during the Horus Heresy and sent their Knights to fight the Chaos forces of the traitorous Warmaster.[3]

Millennia later, they and the Knights of House Althalos and House Thalmus, came to the aid of the Hive World Hexis Alpha, when a Warp rift spawned a tide of Daemons across its surface. More than 100 billion lives were saved, due to the Knight Houses successful efforts in defending the Hive World from the Daemons.[1]

Knights of the House Mortan took part in the Siege of the Fenris System in 999.M41.[4]
