The Umgah are a race of pranksters whose warped sense of humor knows no bounds. They are purple blobbish creatures with multiple eyes, mouths and tentacles. They foster an interest in bio-science, and amuse themselves by affixing extra appendages to their blob-like bodies.
An Umgah is believed to be responsible for condemning the Spathi to a be bound into service as heirarchy Battle Thralls. They are also guilty of impersonating the Ilwrath gods Dogar and Kazon and responsible for the war the Ilwrath wage against the Pkunk.
