Turn of Fortune's Wheel Prelude (spoilers)
Hi I'm planning to DM Turn of Fortune's wheel and I'm thinking of starting my players at level 17.
Heavy spoilers ahead.
In the module, the players wake up in Sigil at level 3 with their memories erased. They find out at the end of the campaign that Shemeshka captured them and their new forms are a due to a universal glitch.
I think it'd be fun to have that showdown happen in the campaign as Prelude. That way they can make connections in Sigil first and during that time I can figure out a good reason for the glitch. The module, as written, is pretty weak on Shemeshka's motivation and the reason for the glitch. Also, why is she making them seek out the modron? Doesn't make much sense. I'm hoping to fill in all that information with some level 17 adventures in Sigil.
Any advice on this? Is that a good idea? Should I just wing it in Sigil adventures or is there a high level adventure that you would recommend that would eventually link well into Turn of Fortune's wheel?
