Rur

Rur was a Force-sensitive male human who lived long before the Galactic Civil War. He led the Ordu Aspectu, a splinter group of the Force-using Jedi Order that sought to achieve immortality. After waging war against each other for some time, the Jedi and the Ordu ended up signing a peace treaty.

In an attempt to create a copy of his intellect, Rur embedded his knowledge on a computer, creating a being known as Eternal Rur. When the orthodox Jedi came to the Citadel of Rur to inspect the computer, the AI took control of droids who started slaughtering everyone on sight. Before the computer's rampage was complete, however, Rur powered it down, causing Eternal Rur to lose consciousness, sacrificing himself in the process.
