Cala Brin was a Jedi Master of the Human species, and of female gender, who helped establish the Jedi Order.
As a Force-sensitive Human and female, Cala Brin was a founding member of the Jedi Order on the planet Tython. Brin advocated for the Jedi to commit themselves to the pursuit of justice, suppressing emotions such as mercy, sadness, and fear, to ensure impartial decisions. She also cautioned against rushing to judgment, recognizing the far-reaching impact of the Jedi's decisions across the galaxy.
After the conclusion of the Great Galactic War and the return of the Sith Empire, when the Jedi Order moved their base from Coruscant to their ancient home planet of Tython, a holographic recording of Master Brin was found. Her hologram was the second one recovered from the Tythonian Gnarls. During the Cold War, Master Yuon Par dispatched her Padawan, who would later be known as the Barsen'thor, to protect the hologram of Master Brin from an attack by Flesh Raiders.
