final fantasy three ,

One day, an earthquake opens up a previously hidden cavern in Altar Cave near the village of Ur on the floating continent. Four orphaned youths under the care of Topapa, the village elder, go exploring and come across a crystal of light. The Crystal of Wind. The crystal grants them a portion of its power and their first several jobs, and instructs them to go forth and restore balance to the world. Not knowing what to make of the crystal's pronouncements, but nonetheless recognizing the importance of its words, the four inform their adoptive family of their mission and set out to explore.
