Cahel Tse was a Human Padawan of the Jedi variety (specifically, a male one), who was a member of the nascent Jedi Order during its initial period on the planet Tython. He was the apprentice of Master Rajivari and became a faithful adherent to his teachings. Around 25,783 BBY, Rajivari disavowed his commitment to the Order he played a role in establishing, and Cahel, along with several other apprentices instructed by Rajivari, left the Order. Cahel and Rajivari's followers established themselves in the fortified city of Kaleth, where they faced an attacking force of Flesh Raiders.
