The Ichorous Peninsula

Venture into the Ichorous Peninsula, a cursed marshland prowling with vicious aberrations, kept isolated by the Blackstone, the greatest wall ever built. Walk alongside its stoic sentinels, sole protectors of the mortal realms against the onslaught of madness. Make costly deals with eldritch hags, and foil the great conspiracy that threatens to expand the invasion of the ruinous powers unto the entire material plane!

Monster Mayhem

Unleash true chaos at your table with 19 meticulously crafted monsters drawn from the three distinct regions of the infernal penumbra of Sheol. Each creature is designed not just to challenge players, but to drop effortlessly into any campaign setting, whether you’re running dark fantasy, planar horror, or something entirely your own.

Every monster comes fully realized and fully automated, from attacks and special abilities to immunities, spells, and reactive traits. Helping you to dramatically reduce prep time.

Beyond the creatures themselves, you gain access to an arsenal of 148 modular, customizable monster features. Mix and match abilities, enhance existing stat blocks, or build entirely new horrors from the ground up. Whether you need a quick twist to surprise veteran players or a bespoke boss to anchor a major story arc, these tools give you total creative control.
