The reclusive Brightwell family has been corrupted by the whispers of a vengeful sorceress-turned-fiend. When this newfound master suddenly grows silent, the madness infecting the household is no longer focused, and cannot be contained. Mayhem spills across the countryside.

Meanwhile, deep below the Brightwell estate, the family’s patriarch Eldon Brightwell inflicts horrifying experiments on both servants and family...

Content Warning: Violence, death/dying, blood, supernatural horror, torture

A house of horrors-style adventure for 4-6 characters of tier 2 (levels 5-10) using the 5th edition of the world's most popular roleplaying game.

The Darkness Beneath Brightwell Manor is a creepy crawl through a noble's estate that has become the scene of ghastly experiments with oozes. Driven insane by the mad speech of a demon, the manor's patriarch has begun a terrifying plot to destroy nearby Dalentown.

Although this adventure includes everything you need to know to run it as a standalone, you can pick up DD-01 The Darkness Beneath Dalentown for additional plot threads or even to connect some of the lower-level dungeons!

This adventure features:

  • An 18 page adventure using a concise, easy to reference landscape layout to make running the adventure even easier.
  • A 40+ page appendices guide with magic items and monsters laid out so that you can easily print and cut them out for arranging as player handouts, initiative cards, or to arrange by encounter!
  • An appendix of lists to make preparation even easier.
  • Links to all magic items and monsters in the adventure text, so you can reference SRD stats and format them to your own wishes.
  • Magic items and monsters sourced from dozens of OGL releases, so you'll get use out of all those 3rd party books you own, or discover something new! Either way, you have all the information at your fingertips in this adventure.
  • Cartography by Dyson Logos and a small hex map using Inkwell Ideas' Worldographer.
  • Easily set in any fantasy RPG campaign setting, but with enough ties to Adventures in Dalentown to give you easy room for expansion, or just an easy place to start!
