A massive flesh cube that imprisons the soul of Sisyphus. It slowly rotates on top of a flesh stalk, like some kind demonic tree. The stalk leads into the base of the cube, whose sides are composed of pallid gray skin reinforced with human bone. Its face is splayed across all horizontal sides of the cube, revealing its eyes, teeth and fleshy gums, but no lips. Its teeth are constantly chattering in a rippling pattern that moves counter to the direction it is rotating. It is incapable of speech.
