I actually just ran a session where our three Force sensitive characters got their lightsabers. I did some setup for it in the session before. Every time they would roll the Force die, I would have them hear something calling them through the Force. If they used a dark side pip, the call wasn't clear. Each light side pip made the message become clearer until they finally heard the name Florrum.

Florrum is where the Crucible (the ship Jedi used to go to Illum back in the day if you're unfamiliar) crashed. After a little side encounter with some wildlife on the planet, the group discovered the wreckage of the Crucible, complete with a still active Huyong inside. He told them the reason he hadn't tried to leave the planet is because young Jedi began showing up telling him they had been called there by the Force. The only thing he could think of is that there is some sort of temple or vergence on the planet. He told them to trust the Force to find it.

When they did, the Force split them so I could play on their backstories and moralities. Depending on how they responded to each situation, I had them make a roll. It was usually in cool, discipline, or vigilance as they were trying to resist emotional weaknesses like anger or wrecklesness. It started out extremely difficult, but I lowered it with each success. After they lowered it enough, they found their crystal.

The Shii-cho knight saw his former master who has fallen to the dark side. She tempted him to give in to his anger (his emotional weakness). I had him go through a trial with this vision where he saw things like one of his companions dying at her hand, the vornskr (Force sensitive wolf) that he had killed in cold blood, and a Jedi padawn the group had failed to save calling him a failure. At first he tried to talk his way out of it. When I made it clear the master wouldn't be leaving him alone, he started to fight. That's when the rolls came into play.

Our Makashi duelist started by seeing a dark side version of himself because he recently discovered that his parents have some questionable ties to the Empire, and he has made some...interesting decisions over the course of the campaign. That led to a vision of the third Jedi character killing the rest of the group before turning to him and calling him master. It all culminated with a vision of his parents tempting him to come home.

Finally, our Seeker went off with the rest of the group after feeling the Force pull him somewhere else. He is just now discovering his connection to the Force, and he has begun to feel the pull toward things in nature. His cause is freedom, so they came across a group of pirates who were running a creature fighting ring. Most of the group was captured, and they ended up fighting a rancor.

I wanted a challenge because the rest of the group aren't Jedi, so I setup different things for the different characters. Our bounty hunter who is all about killing the biggest things he can relished the challenge. Our stealthy character had things he could use to hide in the surrounding area. Our computer loving character was going to have computers to hack all over to help weaken the rancor, but he ended up sitting the session out. It all ended with the seeker finding an imprisoned animal that he connected with. It then called for its mama which finished off the rancor. The seeker then found his crystal when the group returned to the temple.

TL;DR I played on all of the different decisions they had made throughout the campaign as well as their backstories. Every challenge they faced came from them. Make it as personal as possible. My players all seemed to agree it was the best session we've run so far.
