Adept

An Adept is a person in the Golden Sun series who can use Psynergy. There are four types of Adepts, one for each of the elements: Venus (earth), Mars (fire), Jupiter (wind), and Mercury (water).

Generally an Adept can only cast Psynergy of his or her element. However, the elemental spirits known as Djinn (singular: Djinni) can affect an Adept's Psynergy, either granting them Psynergies of other elements (if the Djinni's element is different than the Adept's) or making their existing Psynergy stronger.

Adepts are scattered throughout Weyard, although most tend to be located near sources of great Psynergy. Often this source is a deposit of Psynergy Stones, such as those within Mt. Aleph and the Elemental Rocks. Another possible source is the Elemental Lighthouses, giving birth to the Mercury Clan and explaining why everyone in Prox is a Mars Adept (Prox is just south of Mars Lighthouse) despite the cold climate. The most notable exception is Lemuria: all Lemurians are Mercury Adepts, yet there is no obvious source for this Psynergy.
