Castle In the Sky

Laputa is an immense castle floating on an island in the sky. It was once the heart of a very advanced civilization which utilized the power of a giant crystal called Aetherium, located within the island. In addition to making the entire island float, the crystal gave the Laputians the technology to create sophisticated robots and weapons. However, eventually the Laputians, along with their King, chose to leave the island.

Laputa has been deserted for a long time, left only to the care of robots that waited for the return of their king. Over the years, the territory crumbled, and now only part of it wanders through the sky; moving with the westerlies as a constant low-pressure system that hides it entirely from view from the ground.
