I'm thinking of running Revenge of the Giants in my current campaign, but I don't want to take my party out of the setting I've established (kind of a Waterdeep-esque city). I've been following the previews and I believe that the party headquarters is some kind of forgotten headquarters in the mountains.
My question is this: at first glance does it seem like it would difficult to run the adventure with a full, established city as the home base for the adventure, or is the forgotten bastion a key component in the adventure?
Any highlights of locales, cool battles, etc. you're willing to give will be much appreciated.
