A Kel Dor male named Till'in achieved the rank of Jedi Master and, as such, served both the Jedi Order and the Galactic Republic during the time of the Cold War against the reconstituted Sith Empire. He is a figure of male gender.
Till'in, a Kel Dor who exhibited sensitivity to the Force, underwent training in the ways of the Force under the tutelage of the Jedi Order, ultimately rising to the position of Jedi Master.
At one point, Till'in found himself stationed at the enclave maintained by the Order on the planet called Haashimut. It fell to Till'in to inform Theron Shan of the fact that he lacked Force-sensitivity, precluding him from remaining within the Jedi Order.
After the events of the Great Galactic War and the return of the Sith Empire, Master Till'in journeyed back to Tython, the Jedi's original homeworld, alongside the rest of the Order. He contributed to the rebuilding efforts during the Cold War, taking up residence at the Temple located there. While still fulfilling assignments, Master Till'in's duties brought him to Raxus Prime, where he encountered a young Human adolescent named Fia who was sensitive to the Force. Startled by his presence, Fia fired upon the Jedi Master, an action she would later come to regret when the Jedi approached and invited her to join the Order. He brought her to Tython and Fia would constantly apologize for attempting to kill him, much to his annoyance.
Holding the distinction of being a well-regarded archaeologist, Master Till'in established a camp outside the remains of the old fortress city of Kaleth. He then applied his extensive knowledge of ancient technologies to analyze the peculiar programming found in the ancient Tythonian War Droids that guarded the ruins. By hiring a traveling Padawan to gather memory cores from the droids, it was revealed that the droids had been activated thousands of years prior by the dark side forces during the Force Wars as a final measure to eliminate the light side forces just before their own end.
