Having picked up a couple of the other products by Necromancer Games/Sword and Sorcery Studios, I decided after glancing through Rappan Athuk that this had possibilities as well. First off, let me say that the only disappointing thing about this product is the long wait between part 2, where more info on the lost Temple of Orcus will be presented. This is a good, basic dungeon crawl with several tough encounters. There are enough hooks available so that it can be dropped into any campaign that you are running. Plus, there is plenty of room for a creative DM to add to the dungeon or make it a part of his or her campaign. The toughest creatures that the party will encounter is this module are the Skeletal Warrior (who is a Blackguard), Purple Worms and the Spectral Lich, who resides on a level that the PC's will have to work hard to get to. The treasures are commensurate with the encounters, so the PC's will be happy. Overall, the product is great, it is presented well and easy to follow.
