You were a medical droid for a pre-Empire company, Isotech, that specializes in cyber technology. You had additional clerical duties and we’re an assistant to one of the lead techs.

As the Republic was transitioning into the Empire it became apparent that the Emperor had a particular interest in Cretala, an Arkanian. With the assistance of a Clone Wars Era veteran (Captain Rep Halso?) the cyber tech team escaped in a cruiser but suffered heavy damage just before jumping to hyperspace.
In the chaos that followed you were thrown into a message pod with coordinates of the cruiser to mount a rescue. Sadly, the pod was also damaged and you were left drifting in space for 20 years. You still rest in low power mode (nearly deactivated).

You have records/files on the team, the clone wars vet, and several technical files on both possibly revolutionary cyber tech and medical breakthroughs, but you only have a piece of those files that remain with the ship.

Obsession for Knowledge; belief that knowing the right things at the right time can make the difference. Organic-similar stress/anxiety responses to lack of or known missing of knowledge.

Despite a belief in Droid's Rights, S3N-314 recognizes a great feeling of obligation of service to his owner Cretala, an Arkanian that not only freed him from what would have been mindless medical service, but also upgraded him such that he could not only pursue his own aspirations but decide on them. It is partly this obligation that led him down the scientist track, in some deep seated desire to show his gratitude in earnest to Cretala.

Lightly modified 2-1B Surgical Droid, to facilitate clerical and testing duties in a scientific setting. Worn Jaw bolt, right side, causes a sort of lop-sided grin at certain angles. Newer metal glean to right forearm and hand, fairly obvious replacement.
