R5-J1

R5-J1 was an astromech droid who worked in the droid maintenance shop in the Retreat during the Galactic Civil War between the Galactic Empire and the Alliance to Restore the Republic. The Retreat was a settlement on the planet Cholganna, created by the surviving crew members of the Confederacy of Independent Systems Munificent-class star frigate Sa Nalaor, which crashed on to the planet whilst trying to escape Republic space at the end of the Clone Wars. R5 aided Rewna, the Human survivor in charge, whilst in the shop as much as possible, although its usefulness was limited by the fact it often broke down due to excessive wear.

Behind the scenes
R5-J1 first appeared in 2013 in Beyond the Rim an adventure module written by Sterling Hershey for the Fantasy Flight Games roleplaying game, Star Wars: Edge of the Empire. It was included as a character that players could potentially meet with whilst exploring the Retreat.
