Tales of the Outer Planes is an anthology of short adventures set throughout the many Outer Planes for use with the AD&D Manual of the Planes. Some of gaming's best designers have contributed adventures to this set, which includes scenarios set in the Seven Heavens, Olympus, the four Elemental Planes, the Nine Hells, and the Astral and Ethereal Planes. Tales of the Outer Planes is a perfect collection for powerful characters who have it too easy at home and are looking for new challenges. Many of the most fearsome monsters are even more dangerous on their own planes - can you take them on and live to tell the tale?
As far as all the mystery and wonder of the planes goes, this book doesn't do a very good job at getting it across. The adventures it offer are all fairly banal and mundane - and all too often the party is borrowed magic items to allow them to even survive in their destination, which doesn't help at all. Let the players come up with their own solutions, take them on a quest, or at least have the solution come from a strange and novel place (such as the nymph kiss in the Dungeon adventure Peer Amid The Waters).
