The Fortress of Iron Will is a Casterwill family stronghold located in the Great Rift Valley of Africa. This place is where the Casterwill Elders meet. It is also the location of the Ring of the Legendary Titan of Valor, Mythras. The Stronghold houses many Icarus and Feyone Titans, as well as a Coralgolem Titan, within its statues in order to defend the stronghold. Only the Rune Guardians can activate the guardian Titans through using a long ritual.
