I'm very sick and have had a rough time sleeping, so I just decided to spend some of that time awake doing concept art. There is a lake in Kiwigonia filled with a special kind of holy water that rejects all impurity, but much like a magnet, will pull in anything pure. It will mercilessly drag the holy under and drown them to death. Those beings that are regarded as unclean are capable of walking right across the water's surface. And with a little practice. They can even manipulate the water around them as it rejects their bodies.
