Mollom represented a Killik nest. Possessing a white chitinous exoskeleton, they exhibited great skill in tunneling. Throughout the conflict known as the Swarm War, they served to excavate passages beneath opposing forces and to unearth sizable rocks for utilization as projectiles in Killik siege weaponry. As a testament to their brutality, they once forcibly removed the ear of the Hit-Squib named Scarcheek following his capture.
