Antaeus' Arena

Antaeus' Arena is an arena owned by Antaeus in the Labyrinth. The arena has skulls everywhere which Antaeus supposedly dedicated to his father, Poseidon. Luke and his army needed Antaeus' permission to go through it to make it to Camp Half-Blood.

The Battle of the Labyrinth
After Percy and Annabeth recruited Rachel, a clear sighted mortal, to help guide them through the Labyrinth, they ended up in Anteaus' Arena. It was revealed that the Arena is a crossroad in the Labyrinth, similar to Triple G Ranch, in which users of the Labyrinth must pass through in order to get to Daedalus' workshop. Percy defeats a Scythian Dracanae, Ethan Nakumura, and Antaeus in the arena. But in order to defeat Anteanus, Percy must get Anteanus off the earth as he regenerates where ever he is hit when he touches the earth as he is Gaea's son. They then run out of the arena by creating a distraction in the form of summoning Mrs. O'Leary. Chris Rodriguez mumbled about it, saying, "A thousand skulls..."
