Garet was born in the secluded town of Vale at the base of the dormant volcano Mt. Aleph, as the second of three grandchildren of the Mayor of Vale. For his first fourteen years, he lived a tranquil life there with his family and his friends Isaac, Jenna, and Felix. Garet is a Mars Adept, and all the townspeople of Vale are Adepts to varying degrees because they live their lives under the influence of a giant Psynergy Stone formation near the town's entrance. Garet is described as somewhat oafish and eats a lot. Garet bore witness to the Mt. Aleph boulder disaster when he was fourteen: Mt. Aleph and Vale were beset upon by a terrible thunderstorm, and a giant boulder located somewhere on Mt. Aleph became dislodged and descended upon Vale, crashing through Jenna's house and pier - where Kyle, Felix, and Felix and Jenna's parents at the time were located. All four of of them seemed to disappear right before the eyes of Garet, Isaac, and Jenna. Lost and confused, Garet and Isaac wandered off on on their own, and the two boys were soon accosted by a duo of menacing strangers, Saturos and Menardi, who used their powerful Mars Psynergy to knock Isaac and Garet out cold so they would forget their memories of the duo. The pair of Mars Adepts immediately left the area.
It goes without saying that the period of time following the disaster was very trying for Garet's friends, especially Jenna who had lost her entire family. Garet joined Isaac as they resolved to study the art of Psynergy over the next three years, with the scholar Kraden guiding their toils, to become stronger both for themselves and for everyone else.
