Each one looks almost completely different, bearing a wide array of limbs ranging from extra arms to tentacles, eyeballs on stalks, patches of fur or scales, and other inane combinations.

Some say that simply looking at a demon of madness can break one's sanity.
Madness demons haunt the minds of mortals and attempt to drive them to insanity, speaking in riddles and twisting reality to sow confusion. Their deepest desire is to cause the minds of their victims to snap, driving them to a destroy themselves and others.
