The Keeper

The Keeper was a machine with an artificial intelligence located on Keeper's World. It was accompanied by four android children. Built by a non-violent civilization to preserve their homeworld in a time of war, the Keeper drew its power from its home planet's core, which allowed it to survive long after the people had fled. The Keeper was installed to restore the world to its former status for its makers, so that when they would return years later, the planet would be suitable for them to live on.

Shortly after the Battle of Yavin, Rebel Alliance agents Luke Skywalker and Leia Organa landed on the Keeper's planet seeking shelter from an Imperial fleet. Battling their way through the wilderness with the aid of their two droids, R2-D2 and C-3PO, they stumbled upon the Keeper's Temple, and in turn met the Keeper's four android children. The Keeper was convinced that the Rebels were of good faith, and decided to help them by forcing the Imperial troops that had landed to flee offworld. Skywalker and Organa then left the Keeper in peace to continue her task of building a civilization.
