The Palace of Ontoncle, softback adventure for DragonQuest
“A fantastic role-playing adventure for 4 to 6 players and a Gamesmaster.
- Complete floor plans
- Hundreds of room descriptions
- Briefings for Players and the Gamesmaster”
1980 adventure for DragonQuest, which was SPI’s rival to D&D before the company’s assets were acquired by TSR. This is actually a pretty decent dungeon crawl.
