From the introduction: This adventure can be can be easily customized to a party of any size or level, or run as a level 1 adventure for 5 players. It can work as a small side adventure in an existing campaign, as a standalone one-shot, or the start of a new adventure. ... Flex your open world and improv muscles by running a goblin adventure! An all-goblin party is a good fit for open world since they're naturally mischevious, tend to not be very welcome anywhere, and in case they get into TOO much trouble and end up with a TPK, well everyone expects it since they're just goblins.
