Mugusu was the unfortunate result of an experiment made the Bloodspeaker of the Monastery of Quiet Earth, to create a "superior" form of life. It consisted of several undead bodies stitched upon a living one emerging as a mangled ball of limbs and faces. It moved on six combined legs and attacked with four arms, possesed with supernaturally strength. It attacked by grasping opponents in its limbs and drawing them towards one of the mouths to be bitten.
