Like the Harpies, Centaurs are Beastmen, created by the Wizards of the Seven Cities in the year 512 YSD. Half-human and half-horse, they served their masters honorably as scouts and mobile archery in their armies. But those days came to an end when the Wizards replaced them with their new creations, the animated constructs. The various Golems, Gargoyles, Titans, etc. were simpler to manage, cheaper to keep, and unfailingly obedient. The Centaurs were given less and less noble tasks, and ended up carrying messages and pulling carts. Disgruntled at their loss of prestige, they willingly joined the Revolt of the Beastmen and scattered across the face of Ashan, seeking space, dignity, and freedom. They soon met with the Orc tribes and became their allies, out of common interest and like-mindedness.
