As an idea for a new area: a ship! It could be a pirate ship, but I'm imagining a Flying Dutchman-type ghost ship that drifts around and would be accessible from different coastal and island regions at different (possibly random) times. There could be barnacles and rigging-climbing and a view from the crow's nest and a funny figure-head, and ghosts (pirate ghosts!) and different light-heartedly spooky things, and secrets and treasure (maybe pearls to go with the gems we already have?). Well, I don't know what all should be on it, but I like the idea.
