This book of dungeon geomorphs gives you everything you need to map out exciting underground adventures. The geomorphs are modular map segments designed to be combined in a variety of ways. There are 124 map segments, encompassing mazes, dungeons, underdeep caverns, monstrous lairs, castles, ruins, halls, and many other intriguing places to explore. Together they combine to make thousands of possible maps!

A short adventuring interlude focusing more on encountering something unusual, rather than fighting anything. The PCs come across a tree and a pool inhabited by elves. The nearby brook fizzes with "energy gas" that grants a temporary HP boost. The players can explore, but there are no real "answers" just a weird thing they found on the way from somewhere to somewhere else. Rated for between 1 and 4 characters, this could easily be run for solo play, but it is short and a little weird. There are roleplaying opportunities with the elves, but there's scant data here, the elves are flighty and capricious. Pgs. 38-41
