Here is an example 5 Room Dungeon to inspire your contest entries. In your campaign, you’ll need to flesh out some of the details, but this skeleton format is perfect for GMs to pick up and customize for their own memorable sessions.
The Mad Pope is a wandering mercenary. He is very well deranged as he considers himself to be the pontiff of the dominant faith. His robes are tattered, his mitre has seen better days and there are surely lice in his long ratty beard. What sets him apart from most addle-pated would be holy men is that he has armor under his robes and carries a large crossbow and several one-handed swords. While many would discout him as just another lunatic, for some reason, he inspires others around him and has demonstrated the ability to lay on hands and heal the wounded.
