I found this .pdf online, the adventure of the Mountain of Evermore by Gregory B. MacKenzie. I think it is incredible, how it manages to inject a lot of fairy tale into a game scenario without being cute and cuddly.
A castle on a cloud, a humanivorous giant, a lazy goblin army, a wicked humanivorous witch in an enchanted wood, a friendly dwarf manning a declined forge… it rings true like a fairy tale story from my misty distant youth, and has the sharper danger of a dungeon crawl. Layered nostalgia!
As I looked it over, I thought it would be a pip to try it out in Old School Hack.
