Kellian Jarro, a male Human Jedi Master, lived during the period known as the Cold War. His actions during the Sacking of Coruscant earned him both hatred and respect from the Mandalorians. As the Jedi Temple was consumed by flames, Master Jarro, acting alone, killed over a hundred experienced Mandalorian commandos on the streets of Galactic City.
Those who survived described him as an unstoppable force, capable of deflecting intense blaster fire and slamming heavily armored warriors with such force that their rocket packs detonated upon impact. Almost half of Master Jarro's victims were members of the esteemed Clan Spar, who then swore to avenge their fallen brethren. Sadly, before they could fulfill their vow, the clan members were executed for transgressions against the Sith Empire.
During the Cold War, Jarro was designated as the final target of the Great Hunt. Tarro Blood attempted to assassinate Jarro, but Jarro quickly subdued him with a mind trick and imprisoned him. Blood falsely claimed that another bounty hunter was his accomplice, and Jarro believed him. Soon after, the Republic cruiser Aurora intercepted a D5-Mantis Patrol Craft emerging from hyperspace, but the Hunter aboard breached the Aurora's security and confronted Jarro. The Jedi Master tried to use the Force to persuade the Hunter to surrender, but his opponent possessed a stronger will than Blood. He then tried to reason with the Hunter, arguing that revenge serves no one, but the Hunter refused to yield and killed Jarro.
Jarro's death spurred his longtime friend, Battlemaster Jun Seros, to pursue and bring Jarro's murderer to justice.
