Depa Billaba (Earth-2042)

"You're lucky I'm not my Master. She'd never let you get away with— All the things you tried to get away with?"

- Rahm Kota, to Luke Skywalker

Depa Billaba was a female Force-sensitive Human Chalactan Jedi Master serving the Jedi Order during the final decades of the Republic Era. Trained by Master of the Order Mace Windu and appointed to the Jedi High Council, Billaba was considered one of the most enlightened Jedi of her time and had earned her seat on the High Council. Having mastered the difficult Vaapad lightsaber form created by Windu, she became one of its few practitioners and one of only three masters of the form.
