Oh, an old map! That’s the perfect spark for a yarn. Picture a dusty scroll, ink faded, but still whispering about a vault tucked behind the crumbling stone walls of those ruins. You could spin it as a quest for a forgotten treasure, or a silly twist where the vault is just a giant cookie box left by the original builders. The best part? Throw in a few riddles or a mischievous ghost who keeps the path shifting like a prankster’s game. It’ll give the whole place a life of its own—just like a story that turns the past into adventure.

Got it—no endless riddles, just a quick twist. The ghost will pop in, say a “bake‑you‑be‑baked” line, then vanish, leaving the map’s last clue: a simple symbol pointing to the vault’s door. Inside, the treasure isn’t just gold—it's a book of forgotten jokes that make the ruins laugh every time someone steps inside. That way the vault matters, and the ghost is just a cheeky side note.
