Biography
Isaac was born in the secluded town of Vale at the base of the dormant volcano Mt. Aleph, and for his first fourteen years he lived a tranquil life there with his parents Kyle and Dora and his friends Garet, Jenna, and Felix. Like his parents, Isaac is a Venus 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. Isaac was very reliable and was well-liked by the populace; as an individual, he is virtuous and caring yet not to a fault, and Dora describes him as being so much like his father at his age, including his stubbornness. Isaac used to visit the cottage of the scholar Kraden a lot as well before the elderly alchemist was kidnapped during Saturos' second raid on Sol Sanctum.
Having lived at Vale his entire life, at a mountainous area not close enough to the Great Western Sea, Isaac has never seen an ocean before, like his friends at that point. He, Garet, Ivan, and Mia first see an ocean at the end of the original Golden Sun before setting sail in the Lemurian Ship given to them by Lord Babi.
