In our last session, the PC's were used as unaware and unwilling bait to rescues some Rebel VIP's from an Imperial Prison/workcamp. They pulled out an old NPC friend from our previous campaign, as well as three Rebel VIP's, including Crix Madine (canon smanon) from the solitary confinement wing. They also rescued from this area of the prison the only other prisoner there, an Ugnaught. He kinda tagged along with the group, and they didn't look into his history or why he was imprisoned. In fact, one player said, "He's with the other Rebs, so he must be helpful!". Eventually, this Ugnaught got into a scrap with a PC's recently acquired 'pet', one of the bird-lizards from the Onslaught at Arda I module, and he lost his hand to a bite. And with the flip of a destiny point, the Ugnaught now has a cybernetic hand with swiss-army like tools built in (the group has decided he's there new mechanic), courtesy of the Rebellion.
I think this is all amazing and I'm going with it. Here's my request: What was he in prison for? I want to have some small quirk with this new NPC that suggests what he did to get into prison and in solitary confinement, but am not sure where to go with it. Thoughts?
