Gorth is a character in Warcraft: The Sunwell Trilogy, known for his role as a brutish orc mercenary. He is part of the forces aligned with Dar'Khan Drathir, aiding in his dark plans. Gorth is depicted as physically imposing and aggressive, serving as a minor antagonist in the series. His loyalty to Dar'Khan and his ruthless nature make him a threat to the protagonists, though his role is more of a supporting villain, contributing to the conflicts surrounding the Sunwell's corruption. Despite his strength, Gorth ultimately falls short in the face of the greater powers at play in the story.
