The Adventure said:Adapting the Adventure
If you plan to run The Festival of Dreams as a standalone adventure, Gate Pass can be any embattled city caught between two opposing forces. You can simplify things with the trillith, making them into nightmare monsters summoned by the Ragesians, with no ulterior motive.
If you run the adventure in your own campaign, we encourage you to replace NPCs
in the resistance with ones your players will be familiar with.
