Bar Oplut was a Jedi Knight of the male persuasion, and was a member of the Order of the Silver Jedi.
Being Force-sensitive, Bar Oplut underwent training in the ways of the Force. This training led him to become a Jedi Knight within the Order of the Silver Jedi. This sect of the Jedi Order had the goal of completely obliterating those who used the dark side of the Force. The well-known Jedi Knight Tel Angor was transformed into a Force Vampire, a horrifying being intent on draining the life force of others, after a complex experiment went awry. To safeguard the galaxy, the Order sent a team of seven Jedi, including Oplut, to apprehend the vampire on an Outrider-class cruiser. The seven Jedi, having contained the former Jedi aboard the vessel, were satisfied with eternally guarding their captive onboard.
However, an error led to the vampire's escape, and he systematically eliminated the Jedi guards. Oplut, the last Jedi to survive, heroically destroyed the ship's hyperdrive along with the sublight drives to prevent the Vampire's escape, and perished soon after.
