Dwarves race has lessened over the past few hundred years, this is the only remaining hall that has not been completed destroyed and raided by the demons. Reason being this is completely secret and is almost impossible to find. The place is very well fortified and for the past years Dwarves did not leave this place only grew up here and lived here, for better or for worse. They do know however that demons still rule the high land and one day they may go out and attack the Demon's however for now they are safe as it is no reason to go after another race for no reason. So, all the dwarves in the world live in one concentrated location: Domorian Hall.
