How easy is it to "port" the Lure of the Lost adventure to a group that isn't using the beginner game? I introduced a group to the game a few weeks ago, using the beginner game and Mountaintop Rescue, and they liked it, but they wanted to make their own characters, and didn't have interest in keeping the pre-built ones. However, the little bit I've skimmed through Lure of the Lost seems interesting, and I'd hate to have that adventure go to waste :)
Obviously, I'd need some kind of tie-in to get the players to Spintir to move forward (they don't really want to do the same adventure again), but I noticed throughout Lure of the Lost were references to the pre-built characters. Can those easily be ported to other characters? Would the story lose a lot by having non-Beginner Game characters go through it? Any ideas or suggestions? (I'm a pretty green GM for the game, still learning all the rules myself, but the group was pretty eager to move beyond the limits of the Beginner game, and we'll all be learning things together).
