No Man's Land

From publisher blurb: An Adventure for 4-7 PCs between levels 13-14 Is the party willing to delve into an outpost of Hell to retrieve two stolen holy books? The party meets with a mysterious wizard that shows visions of a hellish future. Can the party descend into an unknown part of Hell itself and return with their souls intact? This is a bit of an unconventional adventure, and is the 7th part of a 7-part adventure series. This adventure takes place in 3 major locations including a battlefield with trenches, land mines and undead strewn everywhere. A holy order attacked by a horde of demons, and an unknown (until now) outpost of Hell called Helvath Tor. The new location of perhaps the two most important holy books in history. This adventure is highly-modular, with many different options available to suit parties of weak, moderate, strong, or ultra-strong levels.
