The Demian Wasteland(s) is a dangerous and very life unfriendly country primarily known to be the home of the Demian race.
Geographically speaking, the country consists mostly of stone and lava, making it a volcanic desert. Very few life forms survive under such extreme conditions, there is barely water, let alone food. The few animals and plants that do survive mostly live underground and are small.
Almost all plants found in the Wasteland have been classified as shrooms, most of the specialized to survive on stone or near strong heat sources. Most animals are reptiles or insects, the largest life-form are the Magma Elementals, which aren't life per se, just magic gone wrong. There have also been sightings of very large reptiles, not unlike Dinosaurs, they are however, unconfirmed so far.
