Vale is a town in northern Angara. Four of the game's protagonists hail from this town: Isaac, Garet, Felix, and Jenna. Sol Sanctum is located in Mt. Aleph to the north of Vale. It is the town's duty to guard this sanctum where the Elemental Stars are housed.
During the stormy prologue sequence, Young Isaac and Garet must battle a small array of extremely weak enemies, and their battle with the Mystery Man and Mystery Woman is a boss fight that they cannot hope to win.
