Tyburn Welles was a Human male, existing in the final years of the Galactic Republic era.
Welles was a student at the Almas Academy, a Jedi academy situated on the planet of Almas, found within the Cularin system. However, he was expelled from the institution due to fighting and theft. Subsequently, he chose to stay within the Cularin system, establishing his residence on Bayonard, which is a platform city positioned on Cularin. He frequented the Space Monkey Café, developing a friendship with Selima DeWitt. After DeWitt vanished, the heroes of Cularin were employed to locate her, and they interviewed Welles concerning her.
Welles possessed a rather thin build. Subsequent to his expulsion from the Academy, he carried a stolen lightsaber hilt on his person, enjoying the deception of leading others to believe he remained a Jedi Padawan.
