The Tower of Atan is a gigantic structure on Tower Island that is known primarily as the location of the Eye of Atan. Its exact date of construction is unknown, though the Sethai claim the Eye of Atan did not become visible until after the Great Cataclysm
A single Tower Guardian stands guard at the tower, though it is said the tower has other defences. An attempt by the Lakhta Hegemony to gain control of the tower failed spectacularly, with their entire force obliterated, and the Tower Guardians subsequently tearing down their embassy.
