'The Mountain Door' is recreated here, rotated 90 degrees clockwise, and surrounded by new areas:
Dumps (Outside)
Before the fortress proper lay a great number of narrow arms and armors, indicating the presence of an army. The party should take note and tread carefully.
Stockpiles (West)
Rooms are filled with centuries old loot, most of which rotted with age. The party may still get lucky and find the odd gold or platinum goblet in here.
-Roll random treasure as if for a small hoard. Or, open the save file and look around whatever room the party's in, roll randomly among items found there.
-For the classic experience, edit out the doors to this area and blank it out.
Secret Passage (In Fortification hall North of stockpiles)
-These stairs are hidden and lead to the Crypt, which is a new addition.
Dormitories (East)
Rooms are garrisoning an army. Doors are barred shut from the other side, but party could either force their way in (DC 20 Str) or find a secret passage to the back entrance. Roll randomly to determine which rooms are occupied and with what; Rooms contain random treasure, can use game save to identify what specifically is in rooms. Alternately, edit out the door to preserve the classic dungeon layout.
Fortified Hall (Replaces Chasm)
The rope bridge over the chasm has been moved to another area of the dungeon. In its place is a hallway with arrow slits. A secret room gives passage to a hidden compartment where archers lie in wait.
Before reaching the bridge, the party may spot the alcove in the southern section. There is a 25-foot gap between the path the party is on, and a ledge with a ramp that goes up to a secret room. This room contains a bag with some treasure, and a passage into the Secret Tunnels below.
