Yep, lots of ways they could do it too. An earlier line lends itself to him having hubris about a power existing on the planet that others were too weak to go in search of. They could definitely use that. Maybe he discovers a cave that's an incredibly ancient temple. Being that he's underestimated the amount of power from this long undisturbed source, it overpowers him, consumes him! When he emerges, he's not the same person anymore in more ways than one. His power in the force is much stronger but the surge of force (I dont know winging it) through his body almost kills him. When Shin finally finds him, he has to spend months in side of a top of the line Boba Fett signature series Bacta Tank. His body does heal from his wounds but he's unrecognizable afterwards.
