The Abomination Vaults of Otari: Into the Gauntlight Tower

About the adventure

Nestled along the foggy coast of the Isle of Kortos, the quiet fishing town of Otari hides a dark secret. Just beyond its cliffs rise the crumbling ruins of Gauntlight Keep — a sinister lighthouse that hasn’t shone its beacon in centuries. But now, strange lights flicker in its tower once more, and whispers of haunting voices drift on the sea breeze. Beneath those ruins yawns a vast, ancient dungeon: the Abomination Vaults, where forgotten magic and monstrous creations stir in the dark. In this campaign, you and your companions will descend into the Vaults’ many levels — each more dangerous than the last — to uncover the truth behind the Gauntlight’s awakening. Along the way, you’ll battle twisted horrors, navigate cunning traps, solve age-old mysteries, and recover treasures thought lost to time. The choices you make will shape Otari’s fate, for the evil slumbering below is patient… but no longer content to sleep. While the Abomination Vaults provide a rich foundation, this adventure will also feature homebrew elements tailored to your party’s backstories, choices, and playstyle. Expect unique encounters, side plots, and surprises that make the story feel like it was built for your characters — because it will be. This game blends rich exploration with tense combat and a thread of mystery that runs from the town’s tavern cellars to the deepest vault chambers. It’s perfect for adventurers who love a good dungeon crawl, crave dangerous encounters, and enjoy piecing together the story of a forgotten past. Whether you’re new to Pathfinder 2E or a seasoned player seeking a challenge, the Abomination Vaults offer a clear path to adventure — and the thrill of seeing how deep you dare to go before the dark swallows you whole.
