In all of Centasi history, from the mythical prehistory of the Old Kingdom to the countless wars and petty conflicts of the modern age of the Hundred, there is no figure so feared, so influential, so historical, as the Howler.
The Sark-Hound is a basic form of Sark which is created for a very specific purpose, to wit, the hunting and killing of the necromancer’s enemies (in Centas, the place of the banal zombie is taken by these creatures).
A group that wished to be 'ever-living' instead was cursed with 'never-dying'. Thier flesh rotted and fell fromthier bones but still they lived on. Now as skeletons they continue thier quest to remove thier curse. As skeletons they differ in that they do not need controlled or summoned. They are fully fledged NPCs with drives or ideas of thier own. Stabbing and slashing weapons would not affect them.
