Shul Vaal, a Jedi Knight belonging to the New Jedi Order, was a male Twi'lek in his middle years. Functioning as a Jedi healer, he worked alongside Jedi Master Cilghal at the Jedi Temple; it was during this time that Jedi Knight Sothais Saar arrived, afflicted by the same illness that had plagued a number of other Knights.
Vaal possessed a comforting demeanor, projecting tranquility even amidst surrounding turmoil.
