From the introduction:
Of all the things trapped within this mad world, Corpse Farmers, remain the only uninterrupted natives.
They are intelligent and gentle, mostly. Violence is unknown within their communities. Philosophically inclined, Corpse Farmers often gather into informal schools to discuss, in depth, the vagaries of darkness, cold, and moral fortitude.
Nevertheless, they are the bane of motile things on treacherous ices.
