Today, all the Primarchs are either damned, lost or dead. As mentioned before, Sanguinius died at the hands of Horus, who in turn later died at the hands of the Emperor. [[Ferrus Manus]] of the [[Iron Hands]] died on [[Istvaan V]] at the start of the heresy.

Over the next thousand years, the other remaining loyalist primarchs died or disappeared one by one. [[Lion El'Jonson]] of the [[Dark Angels]] returned to his homeworld to find it in ruins and the Dark Angel marines he had left rebelled to Chaos. He led a strike force of his own Space Marines against the traitors on the surface and he fought with a burning hate for his lost sons. He was lost amongst the inferno as the world was blasted apart by both a [[Warp Storm|warp storm ]] and a bombardment from his ships in orbit. Whether he stills lives is unknown.
