Pathfinder leans into horror with Bastion of Blasphemies adventure path

If your table wants Pathfinder horror with a real campaign spine, Bastion of Blasphemies is the kind of Adventure Path that asks for buy-in before it asks for dice. Paizo has positioned the new James Jacobs campaign as a complete run for characters levels 5 through 13, with a late July 2026 release and preorder availability through local game stores, Paizo, and Amazon. That makes it less a lore stop than a practical next step for groups coming out of Paizo’s recent beginner-to-mid-level path.

The cleanest setup runs straight through Troubles in Grayce. Paizo described Bastion of Blasphemies as the follow-up to that adventure anthology, and forum discussion added a one-page bridge called The Road to Bastardhall to connect the two books. James Jacobs also said established groups do not need to treat the transition as locked in place, since GMs can let players retrain or swap backgrounds between the two adventures. In table terms, that gives the campaign a built-in on-ramp for returning characters while still leaving room for a fresh party.

The hook is pure gothic Pathfinder. Florin Kindler lost her parents to the Black Coach of Bastardhall, and she is searching for answers tied to a centuries-long curse. Bastardhall itself sits in Ustalav and is framed by Paizo as one of the most infamous haunted castles in the Inner Sea region. The castle is not presented as a moody backdrop alone: Paizo says it is actively hostile, and that those who enter are doomed to vanish forever unless the heroes break the curse. That premise makes the AP a strong fit for groups that like pressure, investigation, and a slow-build descent into a haunted stronghold.

Paizo is also treating the release as a product shift, not just a story beat. Forum posts in 2026 say all Adventure Paths are now being issued as a single physical book, and Paizo’s subscription page says the company normally releases four Adventure Path products per year. The Special Edition will add faux leather, metallic debossed cover elements, and a ribbon bookmark, underscoring that this is being sold as a premium campaign book rather than a serial installment.

That context matters because Bastardhall has been a fan topic for years. In 2019, Jacobs said a full Bastardhall megadungeon was pretty unlikely. Bastion of Blasphemies is the opposite of that old hesitation: a direct, full-length return to one of Golarion’s most memorable horror sites, built for tables ready to spend a whole campaign inside the curse instead of just visiting it.
