Well, at first I was considering going with "do it or die" type things, you know? Like, you're forced to move on because if you don't find a way out, how do you expect to live? But I'd rather leave that as a fallback and I'm currently working on a few other solutions. For a certain few characters, I'd like them to be motivated by the want/need to kick Galileo's ass for ripping them from their world, or maybe even a greedy type actually being in this for the wish Galileo is offering them. I'm still kicking around a few things, but even if a person were to decide not to move on and live off of the natural parts of the labyrinth, I have a little part that kinda makes that impossible. 

Again, hoping I don't have to use that fall back. One of juggled ideas will likely be used, but if you guys have anything to fit there to prevent me from having to use a fallback or prevent railroading, I'm all ears.
