Mordred Deschain was the son of Roland Deschain (White Father), the Crimson King (Red Father), Susannah Dean, (Black Mother), and Mia (White Mother). Mordred was effectively a Were-Spider, able to transform at will from a boy into a deadly spider-like monstrosity. As a result of his accelerated growth, he lived with an extreme and persistent hunger, a condition worsened in his spider state by an accelerated metabolism.
