City of Steel - Brotherhood of Steel
The City of Steel is a cross between Sci-Fi and Medival architecture. Large towers are around the place, and COS streets are always crowded with people.
The Great Palace is where ArchLords convene. It is large and grand and the place will be taking inside Burns office, which is similar in size to the Great Dome meeting room.
