The Earth Crystal can be found in the Ancients' Maze surrounding the Crystal Tower in Final Fantasy III and it is the fourth crystal visited by the Warriors of Light. After all of the elemental shards are obtained, the Warriors of Light gain access to the area where the Ancients' Maze is located and engage Titan, who kept the Crystal corrupted as ordered by Xande, in battle. After restoring the Crystal, it grants the Warriors more jobs, Shaman, Warlock, and Summoner in the NES version and Black Belt, Devout, Magus, Summoner, Sage, and Ninja in the DS version.
