Aven Rolk

Aven Rolk was a Jedi Knight who survived Order 66, and lived into the Rebellion era. Rolk was found frozen in stasis in a decades-old escape pod, and upon awakening and learning of the demise of the Galactic Republic and the Jedi Order, Rolk put out word for other Jedi survivors to gather at the frozen world of Zissh, where he planned to build a new Jedi Temple and rebuild the Jedi Order. Even Luke Skywalker, Rebel hero and Jedi-in-training was planning to go to Zissh, but word reached the Galactic Empire, and a cadre of Force-users, led by Darth Vader himself went to Zissh. Rolk was later found dead in an ice cave, though his spirit persisted as a Force ghost.
