Manus, Father of the Abyss

Manus, Father of the Abyss is a final boss of the AotA expansion. While something of a demon in appearance when encountered by the player, Manus was in fact once human. He became the Father of the Abyss when his humanity went wild, but it is not known what caused this. According to both Marvelous Chester and Hawkeye Gough, an unidentified Primordial Serpent (whether it was Kaathe or Frampt is uncertain) urged the citizens of Oolacile to go delving in the dark of the Abyss, where they awoke this primordial man. Upon awakening, he became enraged and set to expand his domain while seeking out his precious Broken Pendant. The Abyss consumed the citizens of Oolacile, whose humanity went wild in turn, mutating them into ghastly creatures. With inhabitants maddened, Oolacile was left to fall to ruin. Nothing remains in present day to mark the passing of Oolacile, save Dusk.
