- "If you were to brave the Cave of Nyx and battle Cronus, Athena says there is no telling what secrets you might learn from him!"
- ―Erytheia[src]
The Cave of Nyx was a location within Tartarus, named after Nyx. It was where Cronus, spirit of chaos and hunger and father of Zeus, Poseidon, Hades, Demeter, and Hestia, was sentenced to be trapped forever. In the cave, the Wizard dueled Cronus as part of a challenge given by Athena for the Immortal Games.[1] After Cronus was released, the Pirate and their crew later fought Alecto in the cave.[2]
