I like the idea of the PCs being stuck. Try this, the PCs are lost in the mountains being chased by nasty mysterious humanoids and, not knowing the city is mobile, seek cover/shelter in a fortress and trigger the end of a spell that anchored the city in place.

Do you think the set up is fair-ish or too railroad-y?
