FINAL FANTASY CRYSTALCHRONICLES is an action role-playing game developed and published by Square Enix.

It is the fourth main title in the series. It was released on the PlayStation in 1999. The story is set in the world of the same name, a hostile world that the player can travel through. It is the world of the air-ship-like Jindo, where the main character, Hylos, is the captain of the Crystal Caravan.

The story begins with the death of the previous leader of the Crystal Caravan, which causes a civil war between the tribes that inhabit the world. As the war continues, the tribes gradually become more hostile to each other, and it is only a matter of time before one of the tribes is destroyed.

Hylos is the captain of the tribe that is the most powerful of the four, and he sets out to save his people from the other tribes. He does this by finding the hidden truth behind the myth of the goddess Asdivine, the origin of the world, and the reason why the world is falling into destruction.
