This product is a pretty bare-bones affair, and that is exactly why you want to get it. You get 7 pages of "Blue" maps and 7 pages of black and white maps covering over 210 rooms. The rooms are labeled but that is all the description you get. There are sheets for you to detail the rooms with monsters, occupants, and treasure. This is perfect if you want to create a mega-palace for our mysterious Vampire Queen and stock it full of her undead minions. At just under $2.00 it is a steal.
