Unidentified Imperial major

A male individual served as a major in the Imperial Military Sith Empire. Sometime before 3,643 BBY, he encountered the Sith Lord Praven, and the Sith Pureblood took offense to what he saw as a lack of respect on the officer's part. As punishment, Praven choked the major with the Force, breaking the man's neck after forcing an apology out of him.

Behind the scenes
The Imperial major was first mentioned in the 2012 reference guide Star Wars: The Old Republic Encyclopedia, though the guide did not specify the man's name or species.
