- "A Jedi seeks to improve himself through study."
- ―Wettle to Jedi students
A Force-sensitive Twi'lek, Wettle was trained in the ways of the Force by the Jedi Order, eventually attaining the rank of Jedi Master. Following the Great Galactic War and the resurgence of the Sith Empire, Master Wettle returned to the ancestral Jedi homeworld Tython with the rest of the Order and helped rebuild during the Cold War, residing at the Temple there. A heavy-set man, Wettle was a trained Jedi Consular and trained Jedi Padawans in martial arts, a practice he was very knowledgeable at, according to Padawan Hallen.
