Yog'vhus'chuul, Harbinger of the Deeping Void

A lowly worm from the depths of the unconscious leads a tide of alien madness into the world. This supplement presents the creature as a druid of the deep, along with a menagerie of augmented aberrations created to serve elder gods. Designed for use by Game Masters, it includes history, motivations, secrets, dreams, and complete game statistics for low-, mid-, and high-level play. New templates, magic items, feats, and traits support the creature and its servants, with particular use in the Coliseum Morpheuon setting.
