Black Water

The mysterious and deadly water that covers the world and appeared at the same time the Sundered Ones, four hundred years before Harry Iskinder comes onto the scene. It covers the whole planet apart from islands, which are few and far between. It kills in a frightening way: if touched, it pulls its victim into the water, and they never resurface. Not even Sundered Ones (who can touch the water) can bring them back. The only time it’s safe to touch black water is if it’s been separated from the main body of water, as if that separation makes it inert.
