Citadel of the Machines

Aeons pass. A lightning strike causes the ships computer to awaken at last. The only functional mechanical device is a lowly service robot. The HEXADROID. The computer issues a command: go forth onto the planet and explore, to discover a power source that will allow the ship to return home.
