Shadromancer's world named Shado and includes Empty lands and Shado-city.
This place is in "parallel world" and you cannot find it on maps. Nevertheless, shadromancer, who lost his host always find a way to come here. Also Shado has contact with lots of worlds and other species, due to the fact that all of us need sleep.
Due to the fact that outside of Shado-city are only dark lands with black burned ground, these lands called Empty by other shadro. There also lives lots of bit-thing-beasts, "wild shadromancers", and these lands are dangerous. There live only brave shadro, who know, how to fight and protect himself, or simply ones, who don't know about Shado-city and used to survive in these lands.
So, bigger part of shadromancers live in Shado-city. To tell it shorter, they call it just "Shado"...
