Percy Jackson and the Olympians: Legends

The Cave of Trophonius, also known as "The Cave of Nightmares," was a deep chasm home to the oracle, Trophonius, and is located in Bluespring Caverns, an underground cave in Lawrence County, Indiana. It is approximately eighty miles south of Indianapolis.. In order to enter the cave to the oracle, one must first drink from the two fountains of Memory and Forgetfulness. Along with the spirit of Trophonius himself, the cave also contains dark ghostly bees, his sacred animal, and Water moccasins because snakes represent prophetic wisdom from deep in the earth.
