Pathfinder Adventure Path Abomination Vaults (P2) Volume 03

Death lurks in the darkness! The deepest levels of the Abomination Vaults contain massive caverns and a relic left behind by one of the Outer Gods. The heroes must negotiate the ruthless politics of insular drow, vampiric urdefhans, and stranger creatures for the tools they need to vanquish Belcorra Haruvex. Yet even as the heroes grow nearer, the undead sorcerer's power increases, and the heroes must put her to rest before she claims the full might of her malevolent patron.
