About as simple and straightforward as you can get.  This plugin simply removes the lame little chair of Norenen-dur, and replaces it with a cool looking Daedric throne, similar to the one in Kora-dur.  I've also placed a Daedric amulet on the throne to teleport back to the citadel whenever you desire.  I just love the atmosphere of this cell, and wanted a way to get back to it easily without having to run all around the dwemer ruins.
