Rust is located in the Karipti Nebulas system, adjacent to Artery's system, although it was not identified until about ten years ago. Prior to the Conflict Wars, Rust was just a small human civilisation that called itself Resuna and had slowly starting to evolve useful technology. Unaware of the conflicts all around them they started to slowly advance to a computer and communications age. Just as they completed their first space craft, SLA Industries took over the World of Progress and stopped the Conflict Wars.
