In the Dungeons & Dragons role-playing game, Ygorl is the Slaad Lord of Entropy. He is the second oldest slaad lord, after Ssendam, and is considered the de-facto ruler of Outer Plane of Limbo. He is said to have created the Spawning Stone that is the focus of the slaad race, forcing them to take froglike forms rather than their original, purely chaotic shapes.
