Centaurs are a demi-humans race in Drifters,
Centaurs are quadrupeds, possessing the lower torso of a horse and the upper torso of a man. Their faces are somewhat equine in shape.
The Black King sent a squad of centaurs under the command of Minamoto no Yoshitsune to harass the mass of refugees so that they would be driven to Orte. This was to concentrate the majority of the human populations that escape their ruined countries so that the Ends and their allies could wipe humanity in a single swoop.
