Out in the Wisconsin woods is Daniel dragging back a large wooden crate he found sticking out in the dirt. He brings it back to his backyard that ends where the treeline begins, and opens the old crate. On the inside he found a collection of occult looking books, the biggest and most peculiar book was titled "The Tome of Summoning".
As he read it he learns that with this book he can essentially summon fictional characters from their universes. He additionally found a map that he would have to figure out for later. What setting will Daniel pick first to bring out characters?
