No home, no family, no name, and hardly a pony, E-R3 wakes up to find herself a possession of a pony who happened to be on an airship.

Landing in the unfamiliar wasteland, E-R3 finds herself with absolutely no leads on her identity, assuming she was ever a living pony in the first place. Will she discover her identity and work as an agent of peace in the unforgiving wasteland? Or will it break her first, and turn her into a psychotic killing machine?
