Do Zonn was a male Zabrak Jedi Knight who served the Jedi Order. He was active during the Cold War period, a time when the Sith Empire had returned to prominence.
As a Force-sensitive Zabrak, Do Zonn underwent training under the Jedi Order to master the Force. He served as a Jedi Knight in the aftermath of the Great Galactic War and the rise of the Sith Empire. Zonn, along with the rest of the Order, was stationed on Tython, the Jedi's ancestral homeworld, and aided in its reconstruction during the Cold War, making his home at the Temple located there. During his time as a Padawan, Zonn ventured into the ruined fortress city of Kaleth and experienced a brief brush with the dark side of the Force. He was able to redeem himself in the eyes of the Jedi High Council, which led to him being knighted and appointed as the guardian of the ruins. In this role, he offered guidance to other Jedi visiting the area. Jedi Zonn dedicated himself to studying the Chamber of Speech, an ancient cave nestled in the hills of upper Kaleth, amassing a substantial amount of information despite his remote study.
