Before you opens an underground lake larger than any you have ever seen. A black sand coast lays littered with tiny sparkling gemstones, and the ever-present light of radiant crystals overhead is nearly as blinding as the sun itself. Dotted with small rocky outcroppings almost like underground coral reefs, the lake stretches on far past what you can see. But beware, amongst the glowing corals and gently stirring waters are the wrecks of many a ship built to travers this underground ocean. Sirens live here, as do all manner of other threats, both seductive and terrifying.
