Archived: Sons of the Leviathan

The Sons of the Leviathan, also called Medraut's Chosen, are those Renegade Space Marines who followed the X Legion's Knight-Commander of the 5th, Medraut, when they split off from the Knights Azure Space Marine Legion ten-thousand Terran years ago in the aftermath of the Great Sundering. The surviving upper echelons of the Legion's Loyalist remnants swore that so long as even one of the traitor Knights remained alive and unrepentant, the Knights Azure would be unforgivable, and so a Crusade of Vengeance was called.

The Sons of the Leviathan have led this crusade for over ten-thousand standard years, constantly remaining on the move with their other forces in a vast armada. They are known to mysteriously appear and give aid to both Imperiums, though they never take part in any inter-Imperial bickering or skirmishes, and never stay too long. Their goal is the total destruction of Chaos, the Archtraitor Molos brought to trial and execution, and to those with the knowledge of what happened to him, the liberation and redemption of their Primarch, Lotan.
