Murder Maul's were used by members of Ukur Thog-Rommor's band of mercenary killers. Ukur Thog-Rommor was finally killed by the Master of Glass - and both sides rejoiced. Remaining members of his band spread to the outskirts of the world, where most of them disappeared. This version of the Murder Maul has been attached to an Inertial Adjustment Processing Unit, allowing all breeds to wield it.
