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).
"Yn these landes, theye do ryde upone greate flowtinge beastes alike as those thate ye fyshermen do calle nawtilus; Ande these beastes, callede 'pyky-pyky' because of ye noises thate the beastes make, are troubelsome ande beastlye mountes, withe fowle temperes." -Telliamed ap Ynris, "Ye Westerne Landes".
(A levitating giant nautilus that makes a noise like "piki-piki" and is thus called a Great Piki-piki.)
