Tres Osos Caves (Earth-6531)

The Tres Osos Caves ("Three bears" in Spanish) are a system of caves located deep in the northeast Peruvian jungles, and the location of the seal placed upon the Enchantress.

History
The site was originally home to an Inca tribe that worshiped the Enchantress and her brother Incubus were hailed as gods. However, after several years of oppression, this tribe went to revolt against the siblings, being able to seal the Enchantress within an artifact and hide her in a tunnel system within the caves.

The cave system situates in what became present-day Peru, and was explored by American archaeologist, who became lost and released the Enchantress for her torment, who possessed the young woman and used her as a vessel to release Incubus and plot to conquer the world.
