When the mysterious Gauntlight, an eerie landlocked lighthouse, glows with baleful light, the people of Otari know something terrible is beginning. Evil stirs in the depths of the Abomination Vaults, a sprawling dungeon where a wicked sorcerer attempted to raise an army of monsters hundreds of years ago. The town's newest heroes must venture into a sprawling dungeon filled with beasts and traps to prevent a spiteful spellcaster from rising again!

This complete compilation of the original Adventure Path campaign has been adapted to the newest version of the world’s oldest RPG. You’ve heard about the quality and depth of Pathfinder campaigns for years—now explore the Abomination Vaults yourself without having to learn a new game system!

Content Warning: While Abomination Vaults contains typical Pathfinder action and adventure, it also presents themes of suicide, ableism, body horror, and human experimentation. Before you begin, understand that player consent (including that of the Game Master) is vital to a safe and fun play experience for everyone. You should talk with your players before beginning the adventure and modify descriptions or scenarios as appropriate.
