1. That part, we're still figuring out. I think what we told the Piter apper was that he'd be able to get synthetic spice in limited quantities, but there's no real source of spice on the station or on the planet. (There are magmaworms, but they're not true sandworms.)
2. Other Memory should be okay; it's been a while since I read the books so I'd have to check up what all it entails but iirc it wouldn't cause a problem. Precognition would definitely be limited, but we'd be happy to work with you to figure out what would work for both the character and the game.
3. Tentatively no, at least as far as it succeeding, but again, we can work with you to figure out a plot if that's something you're interested in.
