A.C.E.

A.C.E. (Automated Cleaning Entity) is a cyborg aboard The Executrix, a ship bound for some distant world. He was programmed and built to perform maintenance while the ship travels towards its destination, many of the passengers in hypersleep and cryo-pods for the journey. He’s alone, nearly all the time. The crew is kept asleep except for emergencies. So he cleans. Endlessly.
