DEITY
Known as the Fecund Mother and the Black Goat of the Woods with a Thousand Young. A Chaotic Evil Outer God of the Elder Mythos, dedicated to Fertility, Forests, and Monsters.
An Outer God, a monstrous fertility deity said to have spawned a thousand young. Typically understood to exist as a roiling cloud of mist that constantly forms and absorbs hoofs, mouths, eyes, tentacles, and other portions of anatomy, but sometimes when she has to be depicted in a stable form, she is (and/or her spawn are?) depicted as an elephant-legged, multi-mawed aberration.
