One of the three entities collectively known as The Triat in the White Wolf game Werewolf: The Apocalypse. The Wyrm is the entity of corruption that is bent on destroying Gaia. The Wyrm was originally the force of balance in the world, but it was corrupted by The Weaver, another member of The Triat. The Wyrm is directly opposed to the Garou, who are the protectors of Gaia. A large, multi-national corporation, known as Pentex, consorts with the The Wyrm and provide much of the physical force for The Wyrm.

Wyrm is also a term used sometimes to refer to older (usually dangerous) dragons.
