Terek Kelrune was born into a wealthy mixed-race family on Corellia approximately 27 years before the Battle of Yavin. He received a traditional civilian education and upbringing, and when he was just 17, he went traveling in his personal Z-95. Shortly after beginning his travels, though, he encountered a Jedi Master, in hiding. Kr-Ant Jooraw recognized the massive force potential in Terek, and took it upon himself to provide Terek with accelerated training in the ways of the Jedi, and the Force.

At 22, Terek joined the Corellian Defense Force Academy where he proved to be an amazing fighter pilot. A few years after joining one of the Corellian Sector Fleets, he joined the Corellian Special Forces, and earned his Bloodstripes. Shortly before the Battle of Yavin, Terek was granted a leave of absence from the CSF, and secretly joined the Rebellion.

12 years after the Battle of Yavin, Terek was granted entrance to Luke Skywalker's newly-created Jedi Praxeum on Yavin IV. Just a year later, Terek Kelrune was officially Knighted in a private ceremony.

For almost a year, Terek undertook missions for both the Jedi and the New Republic. A little while later, Terek dubbed himself a Jedi Ranger; something of a cross between a traditional Jedi Guardian, and a Jedi Shadow. His missions were mostly of a military nature, and he soon built himself a second lightsaber.

Terek usually wears Jedi tunics very close to the colours and styling of the Jedi of the Old Republic, in honour of his first Master. Terek always carries one lightsaber in a thigh holster on his right leg, and sometimes a second one on his left leg. Terek almost always wears his custom kortosis-armoured bracers and greaves, too.

But in this new age, he also has optional equipment, including a DL-44 heavy blaster; he even has his own starship and fighter, both custom built at Supernova Prototypes R&D.
