MSE-X-PR6 was a customized iteration of the MSE-6 series repair droid, specifically a Rebaxan Columni model, stationed at the research station orbiting Binaros. Originally a typical MSE-6 unit, his role as an inter-personnel courier within the station necessitated alterations: his skill matrix was taken out, and a vocabulator was added. Furthermore, to create a compartment for carrying datapads, his holocam and manipulator arm were removed.
Nevertheless, a malfunction in MSE-X-PR6's software caused him to start committing minor thefts, pilfering intriguing items and stashing them away in the facility's storage area. A thermal detonator and a fragment of DarkStryder technology were the two things he valued most.
MSE-X-PR6 was abandoned when the station was evacuated. Upon the arrival of the FarStar's crew, he volunteered to work as their messenger, driven by loneliness, boredom, and a desire to escape the facility. He was even willing to use the thermal detonator as leverage, or offer the DarkStryder artifact in exchange for transport.
