The Witch of Izalith is a powerful Lord and receiver of one of the four first Lord Souls, along with Lord Gwyn, Gravelord Nito, and The Furtive Pygmy. Her soul, the Soul of Life, allowed her to embody all that was heat and life. Before this, however, she was the mother of the Witches of Chaos, and thus, upon receiving her powers, she created Pyromancy.
During the ancient war with the Everlasting Dragons, the Witch melted the great stone archtrees, home of the dragons. It is known that after this, eventually, it was feared that the flame of her soul would fade- and thus she, along with her daughters, all of whom held a piece of her soul, attempted to create another, with their magic and souls combined. This ultimately failed and birthed the Bed of Chaos, creating demons in the world.
It is known she is the mother of the Chaos Witches, as well as Ceaseless Discharge, her only son.
