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 be bound into service as hierarchy 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.
