As a leading member of the Psikoom, Erak'tabb was a natural choice to be the Oligarch's champion in the assault against the Overworld Riverlands. Indeed, this key Location would secure a foothold for the full-scale M'arrillian invasion. Erak'tabb serves as a personal advisor to the Oligarch, and his mental powers are formidable. For those who fought Erak'tabb at the Riverlands, the Creature quickly became a nightmarish acquaintance. This Chieftain effortlessly penetrated the minds of those too weak to resist- seizing their thoughts and dominating their wills.
