After the life support system on the Laputa (orbital space station/city) fails, the peoples of the Laputa revolt against the Human Council, and an armed conflict ensues. As a result, the Laputa's engines explode and the city is destroyed, killing almost everyone on it. The few survivors escape in space shuttles and find another deserted Laputa in space. This Laputa is equipped with a landing pod to Earth, rumored to be long lost. Now you lead the remaining survivors of the Laputa and re-establish contact with Earth and the mysteries within.
