Legion of the Damned

The Legion of the Damned is a chapter of Space Marines which mysteriously appears to help overwhelmed Imperial forces, then vanishes just as mysteriously, leaving behind only the destruction which it has caused. The troops that make up the Legion of the Damned do not have strict uniform armour like other Space Marine chapters, instead having a variety of flames, bones, and skull patterns on their black armour. The Legion of the Damned is believed to be the remnants of the lost Fire Hawks chapter of Space Marines.
