An ancient people built mystical fortresses made of melted stone; from the wall’s these fortresses defenders appeared to burn with a powerful energy and strike at their opponents with a supernatural force. Today most of these forts are abandoned and the art that made them lost.
A certain tribe in a valley believes that the soul remains trapped in the body after death and is aware of it. So they treat their dead as if they are alive, talking to them and keeping them at home. They are used to the stink and for some reason are also immune to the diseases that this practise causes but outsiders are not so lucky.
