Kolloma Ree held the rank of captain within the Jedi Order, specifically leading the Jedi Temple Guard.
The initial appearance of Kolloma Ree was as an audible voice, created through the combination of a yellow kyber crystal and a Jedi holocron acquired from Star Wars: Galaxy's Edge. The precise spelling of Ree's name was later disclosed by Leland Chee from the Lucasfilm Story Group on the social media platform, Twitter.
