Hesperia

Hesperia is the northern island continent in the Great Western Sea. Its culture resembles Native American mysticism. The most prominent landmark on Hesperia is Shaman Village, which is connected to Trial Road.

History
Long before the main storyline of the Golden Sun games, Hesperia and Atteka were in a constant state of war. Though the war was not elaborated on very much, at the end of the war, a truce was declared in which the sacred treasure of Atteka, the Hover Jade, and the sacred treasure of Hesperia, the Shaman's Rod, were traded for a peace agreement. It wouldn't be until Felix's party appeared in Hesperia that the treasures returned to their rightful continents.

An often overlooked fact about Hesperia is that it was originally attached to Angara, as can be seen on the first game's in-game map. This is explained when Isaac's party returns to Vale after the Kalay bridge is repaired, where several NPCs talk about how Mt. Aleph's eruption "tore the continent in two".

Cultural references
Hesperia perhaps refers to the Hesperides, nymphs of the west in ancient Greek mythology who were daughters of Atlas. In Golden Sun, Hesperia is also in the west of Weyard.
