Dalic was a Twi'lek Jedi in training at the academy on Coruscant. Just before the slaughter brought forth by order 66 Dalic fled and sought refuge on the planet Dathomir. Dathomir was the home of Force sensitive "Witches," who were the descendants of a fallen Jedi banished to that world. With these witches Dalic was able to continue his training in the Jedi arts. To the extent he no longer needed his eyes. Dalic has since roamed the universe in search of an ancient artifact sought after by the same witches that finished his training.
