A Theelin Jedi served the Jedi Order during the High Republic Era. On the astronomical object Blarrum in 231 BBY, the Theelin and an Aki-Aki Jedi searched for the wanted beast-trader Triv Blago in Kul Kenada Spaceport. The Theelin and the Aki-Aki confronted Blago while the trader was having a disagreement with the monster hunter Ty Yorrick, who fled and left them to the Jedi.
A Force-sensitive Theelin was a Jedi of the Jedi Order during the High Republic Era. In 231 BBY, the Theelin, alongside an Aki-Aki Jedi, sought to apprehend the Faust beast-trader Triv Blago, who was wanted for the illegal capture and transportation of dangerous animals. The two Jedi searched for Blago in Kul Kenada Spaceport on the Outer Rim astronomical object Blarrum.
The Jedi confront Triv Blago and their guards on Blarrum.
While the Theelin presented a hologram of Blago to a human, the former Jedi–turned–monster hunter Ty Yorrick, who was returning to the trader after killing an escaped prize gundark they had sent her to capture, attempted to sneak past without the two Jedi sensing her, although the Aki-Aki glanced in the direction she had traveled. Shortly afterward, the two Jedi confronted Blago as the trader was about to have their guards shoot Yorrick for her failure. The Theelin ordered Blago to surrender, and the two Jedi deflected the blaster fire of the trader's subordinates. As the Theelin and the Aki-Aki fought the guards, Yorrick escaped on a speeder and abandoned Blago, and the two Jedi apprehended the beast-trader.
As a member of the Jedi Order, the Theelin was a Force-sensitive trained to wield the Force. They were able to utilize a lightsaber.
The Theelin Jedi wielded a green-bladed lightsaber. They wore Jedi apparel consisting of a brown cloak over a light brown tunic and dark brown pants, as well as a brown belt and black boots. The Jedi carried a holoprojector to display an image of Blago while searching for the beast-trader.
The Theelin Jedi appeared, albeit unidentified, in the first issue of the comic miniseries Star Wars: The High Republic Adventures — The Monster of Temple Peak, written by Cavan Scott, illustrated by Rachael Stott, and published by IDW Publishing as part of the Star Wars: The High Republic multimedia initiative's Phase I on August 11, 2021.
