he depths of the Surface world's lakes and oceans are home to many strange places, just as are the domains of the land. Castle Aquarius beneath the Crystal Lake is one such, a fortress built of coral and seastone, guarded by proud sea-horse warriors clad in coral armor and ruled by the wise King Aquarius. All manner of other sea creatures can be found in this realm, from the tiny guppies to immense whales. In between the extremes are vicious sharks, playful dolphins, ravenous jellyfish, semi-mobile starfish, and many more creatures.
