Plot: A Not!Dwarf from Not!Hobbit (Dorf?) discovers how to make crude gunpowder weapons. He outfits a small team and ventures (with great success) to fight Trolls. But when they return, they are accused of dragon-worship by the elders (guns make fire and smoke, just as dragonbreath).
Idea: Why science is not working in most fantasy worlds?
