Seliorus

Seliorus, otherwise known as The Hollow Domain is a corrupted marshland that very few call home. If contact with the tainted water is made, there are two outcomes. One of said outcomes is the far more common one; a disease that turns organic tissue to stone. Unfortunately, this is the fate of the majority of those who attempt to explore these lands in search of myths and legends. However, there is another outcome, albiet much, much more rare. On occasion, when a living creature touches the water of the marsh, they are not turned to stone. Rather, they are transformed and molded by the water, effectively creating a new species. Each seperate race that touches the water has the chance to birth a certain species (ex. Elves turn to Yr'ihr, Humans turn to Dor'mun, etc.). The overall landscape is fairly unhabitable as well, not counting the corrupted water. The few plants that are left alive within the marsh are withering, often glowing abominations, and the few splotches of wet land are often seperated by the tainted water, making traversability difficult, if not impossible.
