It would be about any memorable person from any time period coming together on a massive island. The Island would have many mythical creatures on it. Dinosaurs, Giants, Ogres, Orcs. Any mythological and fantasy creatures you could think of is probably on this island. Obvious since everyone would be from different eras they would have memory of how they got here. They don't exactly wash up though. They just wake up in a straw hut somewhere in the island.

Ideas are wanted! This is just a rough idea right now.
