Straghess

A corpse fiend comprising countless bodies and discarded detritus. However they are torn apart or pulverized, their communal resentment writhes with determination, outwitting every form of annihilation.
This obsessive mound of flesh, unlike any form of life ever to exist, has no obvious weakness.
