The goblins in Goblins of Gourm share a number of traits with "typical" goblins. They are malicious, creepy, little guys. As the adventure progresses, however, the PCs will run into goblins who are increasingly unlike the stereotype. Goblin farmers aren't a huge stretch. Goblins need to eat, and - despite D&D's tropes - raiding is not a sustainable method of food gathering.
What about a technologically advanced goblin civilization? A goblin bureaucracy? Goblin artists? There's definitely an underlying creepiness to the whole thing, and the civilization is fairly alien, but can this still work with goblins?
I hope so. Sometimes I worry.
