Re-engineering was a process of genetic engineering employed by the corporation Arkanian Microtechnologies to make both sentient and non-sentient beings stronger, more docile, and less intelligent. In the process, the subjects also gained a strange Force signature that made them feel "wrong" or unnatural to Force-sensitives, and which made them frighten non-sentient creatures, such as banthas. The Gand Findsman Vaskau Farg encountered several re-engineering subjects in an Arkanian Microtechnologies facility on the planet Arkania while trying to claim a bounty on a Sakiyan scientist—a "witch" to him—who was consulting on the project.
