Temple of the Ancient

Located on a small island, the Temple of the Ancients is a large structure into which the Ancients transformed the Black Materia to prevent its use. Whoever wishes to turn the building back into the Black Materia must sacrifice his or her life by solving a series of puzzles that shrinks the temple back to its original size, crushing whoever is inside.[13] To the south-east of the Temple of The Ancients lies the only other inhabited island on Gaia, Mideel Island, a sub-tropical area where the Lifestream sometimes breaks through from inside the planet.
