Yenjai Sedbin

Yenjai Sedbin was a Jedi Master in the Order leading up to the attack at the Jedi Temple, where he abandoned the jedi after killing Jedi Knight Cass. He is one the main characters in the Retribution series.

Early Life
Not much is known about Yenjai's childhood. He was born in Alderaan around 30 years before the Great Galactic War. He was then taken to Coruscant to complete his Jedi training by Master Tobi.

Jedi Knight
Sedbin became a Jedi Knight at age 22. He and his master, Tobi were known widely throughout the council and Coruscant, especially after saving Senator Mancer from an assailant known as Fresamop.

Great Galactic War
At age 29, Sedbin became a Jedi Master, with his own padawan, Cass. They served in the battle of Korriban, which ended in defeat for the Republic. They also battled in Second Battle of Bothawui, the Republic's first win. Sedbin, without Cass, fought in the battle of Alderaan, his home planet. The Republic, again took a win from the Sith and Imperials.

Sacking of Coruscant
Yenjai, one of the members of the council who had stayed while few negotiated with Imperials, came to shock to find that a Sith fleet approached the temple, lead by Darth Malgus. A bloody battle began: Sith vs Jedi. Yenjai found himself and Cass fighting Sith Lord Rydan. While fighting, Rydan jumped up as both Sedbin and Cass attacked him. Sedbin had stabbed Cass through the chest killing him. His anger grew and he began wailing on Rydan, until he had sliced of his arm. Rydan hit the ground but 7 more Sith, including Lord Skandar arrived to his aid. Sedbin evacuated to temple, leaving the other jedi to die. Before the Imperial fleet could blockade the planet, Sedbin was able to escape in his ship, deserting the order.
