List of references to Greek mythology in the Halo series

Greek mythology has been an inspiration for many names of locations, vehicles, ships and operations in the Halo Universe.

Locations

 * Tartarus: Tartarus was named after the worst, most cruel part of the Underworld, where the original Cyclopes and Hekatonkheires were sealed by their Titan parents, and later the Titans themselves became inhabitants of Tartarus. The worst people and things were said to go to Tartarus for eternal torture, as is referenced to when Tartarus burns the Mark of Shame into the Arbiter as punishment for failing to protect Halo.
