Now, this campaign is still a work in progress. The idea may be kind of over the top, but I still think it would make a good, fun campaign for more experinced players.
Years ago, during the days of the really old Republic, in the times of the Mandalorian Wars, there was a small band of adventurers. They all came from separate pasts, but int the end found themselves all caught up in the plans of the nefarious ZI- ZO (I believe that was his name: he's the evil floating droid from KotOR 2). ZI-ZO had the adventurers go and try to find him some of the ships from the recent Sith War, and possibly the remnants of the Star Forge. However, though the players indeed found a large stash of ships on an out of the way planet, they tried to get away and sell the ships themselves (or give it to the current regent, or do something else along those lines). ZI-ZO was furious, of course, and as punishment, had the adventurers frozen in carbonate, where they have remained up until this day...
... That is, before they were discovered by another group of adventurers, hidden in an underground base on some distant planet.
The actual story is still at large (what do they do know?) but the basis is that the players are now 2,000 years in the future. The reason why this would be for more experienced players is because they'd need to remember that they are from the past and now they are in the future.
Anywho, it's just an idea, and I'm just spit balling here. If anyone wants to add some input, I'd appreciate it.
