10 Rubric Marines
Stepping out from the fog of battle come the Rubricae. Many of these timeless warriors were once psykers in their own right, before an ancient curse damned them to an eternity as living husks – their baroque power armour now encases nothing but glowing dust. In battle, a malevolent witch-light crackles round the eyes of these traitor Space Marines as they open fire on those they would have once referred to as brothers. Their infernal weaponry spits plumes of warpfire into the ranks of the foe, flesh and molten armour exploding in all directions as salvo after salvo hits home.
