The Dark World is a world that exists only around the Dark Fountain, merging with the Light World and manifesting within it as dark places. Entering these places will transport you to the Dark World. The Dark World is home to Darkners. Darkners are unusual creatures of varied, sometimes somewhat bizarre, shapes and sizes, which appear to be ordinary objects in the Light World. They remember their existence and nature in the Light World and carry this over into the Dark World as their character, appearance, and behavior. Because of this, their unusual appearance depends entirely on where in the Light World the Dark Fountain was opened and what objects it attracted when it opened.
When the Dark Fountain closes, the Dark World disappears, and all Darkers within it turn back into objects. + If Darkers end up in another Dark World, they turn to stone.
