The most important place in the Evil Master's abode. You'll spend most of the time here. The Throne Room is a place where you can look through available quests and chose the areas where you want to get to by the teleport. You can save the game there. All these options are available if the Overlord sits on the throne.
What's more, the Throne Room is something like the junction. You can get to other rooms from the Throne Room. You'll find stairs behind the throne. They lead to the Overlord's apartment. The passages to the Forge and Burrows are opposite the throne.
In Nodrberg Sanctuary you'll find the harp. Thanks to it there will be a band which will give a concert of sung poetry on demand of the Evil Master.
