Sixth Brother

The Bil Valen was a fallen Jedi Knight who joined the Galactic Empire as the Inquisitor Sixth Brother under the command of Darth Vader.

He was present at the Works when the Grand Inquisitor introduced Vader as their new trainer and master. The Sixth Brother's training under the Dark Lord of the Sith earned him a dismembered arm, which was meant to teach him "loss".

The Sixth Brother later followed Vader and fellow Inquisitors on their hunt for Jedi Knight Ferren Barr, who was advising King Lee-Char against the Empire. At Vader's orders, the Inquisitors went alone after their main target. Cornered, Barr revealed his pursuers' identities as former Jedi, which caused the Purge Troopers to enact Order 66. To flee the clones, the Sixth Brother unceremoniously cut off the Ninth Sister's leg to leave her behind, in order to slow the Purge Troopers down.
