- "Nikolaos warned me about snakes in the grass, but I wasn't expecting this."

The Snake Temple, also called the Snake Ruins, was a ruined temple within the Valley of the Snake in Phokis, Greece. It was so named for the giant skeleton of a gigantic snake wound around the rocks of the ruins.
During the Peloponnesian War, the ruins were visited by the misthios Kassandra, in her quest to locate and assassinate Elpenor, a member of the Cult of Kosmos. After eliminating the Cultist guards in the ruins, Kassandra travelled to the nearby cave and slew Elpenor, recovering an Artifact Fragment, an outfit and mask from him.
