The Dark Brood

The Dark Brood slithers from the fertile womb of Shub-Niggurath; undulating and hideous copious, it births strange and impossible children.

The Dark Brood offers a selection of content, bringing the fecundity of Shub-Niggurath front and centre to your game and letting her mindless progeny loose upon the world. The supplement has been edited and expanded since the original release and updated to align with changes made in the second edition of Cthulhu Hack (CH2e).

• An overview of the Black Goat of a Thousand Young and the manifestations of its presence


• Six ready-to-play creatures of Dark Brood, updated to CH2e format


• Three investigation seeds, each with three hooks to engage your investigators and a background of what they’ll uncover


• Worship and worshippers of the All-Mother, outlining six different follower types, each with their idiosyncrasies in appearance and ability


• Five new Mythos rituals associated with practitioners close to Shub-Niggurath


• Dozens of ideas on adding the influence of the Dark Brood and Shub-Niggurath into your investigations, which you can use as hooks, flavour, or creative sparks for your next investigation

Written for use with Cthulhu Hack, the simplicity of the system and light mechanics mean that ideas and content can easily be adapted to other investigation horror systems.

Publisher Note: This investigation is written for Cthulhu Hack 2nd Edition but can be used with the first edition with minimal changes.
