Adept

An Adept (エナジスト Energist) is a person in the Golden Sun series who can use Psynergy. They were called Jenei (ジエネス Jienese) in the ancient past. There are five types of Adepts, one for each of the elements—Venus (earth), Mars (fire), Jupiter (wind), and Mercury (water)—and a fifth non-element class called "Dark Adepts" or the "Umbra Clan" (Umbra being Latin for shadow).

Characteristics
As mentioned, Adepts are people with the ability to use Psynergy. Adepts are usually aligned with a specific element, and thus can be classified by that element, such as a Venus Adept or a Mars Adept. Generally, Adepts can only cast Psynergy of their own elements, but spirits known as Djinn (singular: Djinni) can grant Psynergy of other elements if the Djinni's element is different from the Adept's.

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, like those within Mt. Aleph and the Elemental Rocks. Elemental Lighthouses are also possible sources, giving birth to the Mercury Clan and explaining why everyone in Prox is a Mars Adept (Prox lying just south of the Mars Lighthouse) despite the frigid climate. The most notable exception is Lemuria, where all the city's denizens are Mercury Adepts, yet without an obvious source for this Psynergy.

History
In ancient times, Adepts were known as Jenei, and were said to rule the world. With their powers, they created various machinery that harnessed the power of the elements. One tribe of Jenei, known as the Neox, was noted to specifically watch over the Ei-Jei region, and was allied with the Exathi, a race of skilled craftsmen. However, when Alchemy was sealed away, the Jenei as a race largely vanished, leaving only small groups of Adepts located near powerful sources of Psynergy.

By the time of Golden Sun, Adepts as a race were unknown, as many Adepts specifally made a point of hiding their powers. One such group of Adepts was located in the village of Vale, near the foot of Mt. Aleph. Adepts came to the attention of the world due to the efforts of the Warriors of Vale, a group of young Adepts who journeyed the world in an attempt to revive Alchemy. During their journey, the Warriors of Vale met up with other groups of Adepts around the world. They also found out that as a result of the eruption of Mt. Aleph, random humans became Adepts via encounter with Psynergy Stones.

Following the Golden Sun event, Adepts became known throughout the world, with several countries attempting to hire Adepts as mercenaries to assist in their countries' expansion efforts. In addition, another type of Adept came to light, Dark Adepts, who could wield Dark Psynergy. Furthermore, it is implied that a sixth type, Adepts who could control Light, also appeared as a result of exposure to the intense light of the Apollo Lens.

Once Isaac and his friends defeat his angered self and revive his kind self, he uses his Psynergy to free the people from the curse. His element is never mentioned, but he's assumed to be a Venus Adept, since he has the power to turn people into trees and the attacks he uses in battle are Earth element attacks.

Laurel - One of the guardian spirits and "mother" of Kolima forest. Along with Tret, she was struck by Psynergy stones and was granted Psynergy, but unlike Tret, Laurel was filled with sorrow, this being the reason why her powers are different from Tret's.
