Fantasy RPG Rulebook by Onyx Path Publishing
You must dig. You must explore. You must map. You must build. You must defend. The World Below provides, but only to the worthy. The unworthy fall, consumed by bugs, lava, acidic fog, the vagaries of Kaos, and the World Below’s convulsing tunnels.

The World Below is a game of adversity, heroism, terror, and awe. Your characters will overcome or be defeated by terrible beasts, environmental calamities, and Kaos storms ravaging their surroundings and the souls they encounter. They will chart their journeys, chronicle their tales, and pass their stories down to their descendants, who will, in turn, become your characters when your old ones perish or retire.

The World Below is a complete tabletop roleplaying game. It includes:
- Numerous playable options, some from the traditional fantasy mold, others unique to the World Below.
- The complete Storypath Ultra System, allowing you to play this game straight from the book.
- Myriad settings, monsters, powers, and abilities for use in your stories, which you can play as minimalist dungeon crawls or World Below-spanning expeditions.
The World Below Core Rulebook is available through DriveThruRPG in Print and PDF.
