12 BRIDGE. This walkway is open to the air and the four foot high walls are crenelated. Anyone peering over the side will be able to see down into Room 16 of the First Floor, because that room has a glass ceiling. To the south is the bulk of the Southwest Tower, rising high into the sky. To the north can be seen the mountains of the Crim Zif. Astute adventurers will realize that it is quite possible to levitate, fly, or climb to Areas 3 and 16 of the Fifth Floor.
