After the Clone Wars, the Empire siezed all remnants of the Separtist Army, shipping everything off to various storage facilities. A decade later, a project to retrofit several of the old droids to function in the new Empire began. Most of the larger droids have been deemed impractical, due to all of the Empires forces being humanoid. B1-412 is in the first batch of prototypes, all of which were B1 units, due to their simple hardware designs and the vast quantity of them.

B1-412 is programmed to enforce the Empire's laws, and protect his charge.

Oath- Programmed to protect Inquisitor at any cost.

B1-412 looks like a standard B1 battle droid. His shell is painted Imperial black, with white accents, and an Imperial symbol on his right shoulder.
