From the back of the book:
Prepare for Harley Stroh’s sword-and-planet fantasy epic!
Your characters are cast across the cosmos to a foreign world. Left to die beneath a weirdling sun and its sickening rays, their survival depends as much upon a quick wit as a quick blade. Even the finest chain hauberk must fail beneath the crush of an alien horde.
DCC RPG Tome of Adventure Volume 4 is a level 4 exploration-style adventure spanning scores of leagues. On the Purple Planet, your characters cross hundreds of miles of alien wasteland, where they face predatory creatures, deadly mushroom jungles, and thousands of factious savage man-beasts locked in an endless war.
In the course of the sprawling hex-crawl, characters have the opportunity to assume mastery of their own warbands, pit faction against faction, plumb ancient burial mounds, respect the age-old taboos, and experiment with deadly artifacts – the remnants of the Last War.
How characters meet each challenge determines whether they discover the secrets to returning home, or slip beneath the sands of the wastes, succumbing to the perils of the Purple Planet.
For those few with the courage to remain, we offer a world for the conquering.
