Find somewhere to build a dungeon

"So here's the deal," you say to Daisy, who's skipping along merrily by your side. "You know how the world we live in is full of dungeons? Underground labyrinths full of traps and monsters, that adventurers delve into in search of experience and treasure? You know how that's a major part of our economy?"

"Sure. It's pretty normal in a fantasy world like this."

"I think I'd like to build one. I'd construct a huge subterranean maze, put a bunch of traps and monsters in it, find something priceless to put at the bottom and set up a big boss monster to watch over it. Then, we'd get to watch as adventurers came from all around to try their luck at getting the treasure. Doesn't that sound fun?"

"Gee, I don't know, Raider. Sounds like an awful lot of hard work."

"Did I mention what kind of traps and monsters I'd have?"

"I don't think you did, Raider."

"I'd have stripping traps and pervert monsters."

"So where do we start?"

"Well, first we need to decide what part of the world we're going to put our dungeon in. Do you have any suggestions?"
