Hektor Heresy Chaos Forces
Even before the Emperor graced ancient Terra with his steps, the maelstrom had corrupted men's minds to feel the taint of the dark pantheon.The following is a list of the traitor forces, excluding Space marines, that exist the serve their dark masters.
Traitor Guard
Traitor Titan Legions and Dark Mechanicus
Legio Olitiau ‘Fell Bats’
Hailing from the Night Forge World of Nerezza, lit only by the fires of a thousand forges, the Legio Olitau specialized in night attacks, their titans half-glimpsed dark shapes like primeval gods destroying all who stood before them. Even before the heresy it was said they had been stained by the dark, their use of Terror tactics like chaining dead foes to their Titans and occasionally cladding their titans in the flayed hides of enemies when the fight got particularly tough to break their spirits elicited note from those who fought alongside them. This would swell to encompass the Legion as the Heresy broke out, and soon the Titans of the Fell Bats wore twisted faces and living foes chained to their armour to act as human shields as the Dark Gods took them.
Legio Yache 'Snow Stalkers'
Traitor Knight Houses
House Castus- House Castus is a band of renegades, formerly Imperial Knights, that worship Khorne. They are based in the Eye of Terror under the command of Chaos Lord Teutates.
