Are there any Shadow World adventures set on one of the Moons?
I don't think so (or maybe in one of the TotL ? I didn't read them all). But it's fairly easy : have a portal open under their feet, get them portalled to any inhabited moon, preferably Charon, and enjoy watching Inis or Moralis slap them around
(with the rationale that if you're here, you must *like* that, right ?)
