Keerko was a Rodian Jedi Master who served as battlemaster for the Coruscant Jedi Temple from 532 BBY to 480 BBY. After he retired from training, Keerko roamed the galaxy in search of lost fighting traditions and ancient weapons. He discovered several forgotten sword fighting methods from the pre-Republic era, including an entire miscellany of techniques from the Chatos Academy. After his travels around the galaxy were finished, Keerko returned to Coruscant and wrote a comprehensive lightsaber training manual called The Dance of Light which became an influential text for generations of Jedi.
