Because the project is going quite well now, I made a small picture that will explain the different levels of Barad-Dûr. Notice that I used the Movie version of Barad-Dûr, because it looks in my eyes better.
Red: Place where the eye will be located
Blue: throne-room and personal rooms for the Lord of Mordor (Aidan)
Purple: Topmost: rooms for the Witch King (Er_Murazor) and Mouth of Sauron (Shockblaster)
Mid-level: rooms for high ranking commanders and leaders of other evil-factions.
Lower level: most important commanders of other factions will have their room here.
Yellow: Uppermost farm area, and rooms for guests and the ones who worked on Barad-Dûr, as a way of saying Thank You.
Red: Farms for Barad-Dûr
Brown: Training camps for recruits, smaller houses near the third wall. All recruits must atleast train one week here.
Orange: The Pits: if you don't do what your commanders order you, you might end up here. Also location of the main Storage area.
There will be optional rooms ofcourse, but these are the things that must be included. If there is too much rooms, we always can add storages, brewery's, armory, etc. If you have ideas to add, please leave a comment!
Anyway, near Barad-Dûr will come a wall where you can put up a sign with your name on it, so we can look who helped and who deserves his/her personal room in the tower.
