The Witch of Izalith attempted to duplicate the First Flame from a soul, but instead created a distorted being of chaos and fire. Its power formed a bed of life which consumed the witch and her followers: The Bed of Chaos, source of all demons.
The Bed takes the form of a huge, gnarled tree, with a humanoid body shape. It attacks with two arm-like limbs, and eventually sprouts flaming limbs that resemble wings from an apparition on its back, with which it also attacks. An insect-like creature is seen to scuttle into the tree upon the player's approach, and must be slain to defeat the boss. The insect-like creature contains the Lord Soul belonging to the Witch, suggesting it is what remains of her after millenia spend in the Bed.
