Tresfor was a Twi'lek physician of the male persuasion, according to legends, who was employed at Ja'Boag's establishment on Moorjhone during the era of the Clone Wars. This conflict pitted the Galactic Republic against the Confederacy of Independent Systems. During the year 20 BBY, Tresfor supervised the healing processes of Jedi Master Judd and his Padawan Dray, following their engagement with Darth Maul and Savage Opress. Dray's severed hands were reattached inside a bacta tank, while Judd's fractured arm was allowed to mend. When Judd inquired of Tresfor about the people of Moorjhone and their experiences under Ja'boag's authority, the Twi'lek initially hesitated. However, after Judd's continued probing, Tresfor advised him to observe the heavens for insight, mentioning the approaching Day of Three Suns.
