Azlyn Rae suffered grievous injuries after she stabbed Darth Krayt with her lightsaber. She was supposed to die but Cade Skywalker used his Force healing to keep her alive, enough to get her to Kiffex and treated by Bantha Rawk and his wife. Realizing that she needs constant bacta treatment to stay alive, they used a modified version of Darth Vader’s armor to encase her in bacta.
