Antinnis Tremayne was a Human male Jedi Knight who served as a healer specializing in the study of the brain. Working with the Jedi Security Corps, Tremayne helped those Force Adepts who were arrested for crimes by the Jedi Order to return to the light and come back into Balance. The former Padawan of Dav Kylanu, Tremayne was captured by the Shadow Collective during the Clone Wars after his master was killed and was held prisoner on Byss for the rest of the war. Rescued from Byss by the Jedi following the death of the Dark Lord of the Sith, Darth Sidious, Tremayne was returned to Coruscant where he received therapy for the torture he had received on Byss.
