Old Dominion: Kataphraktoi (pronounced "cat-a-fract-tee")

Armored from head to toe, Cataphracts were the precursors to the noble ideal of the knight. Raised in undeath these horsemen become a terrifying force on the battlefield, their effectiveness compounded by the fact neither the horse nor the rider know fear or pain, allowing them to slam into enemy formations with a ferocity no mortal foe could match.
