Gaia Rock

Gaia Rock (known to the locals as Mt. Mikage) is a mandatory dungeon in Golden Sun: The Lost Age. It is one of the four Elemental Rocks scattered across Weyard, and one of the few locations visitable in Weyard's would-be northern hemisphere in TLA. Gaia Rock is east of Izumo and is home to the Serpent that has terrorized it's people. Gaia Rock is the elemental rock of Earth and as such the Psynergy found in the dungeon is Sand. It differs with the three other Elemental Rocks quite a bit in how it is traversed and that it is the only one that holds a boss fight at the end. Gaia Rock is also more relevant to the overall plot of TLA as it is entwined with the people of Izumo.
