Inside you’ll find rules for four new types of angel, the fell-handed messengers of the Heart Itself which infiltrate and smash apart havens. You’ll also enjoy in-character ramblings on them from washed-up pulp fiction author Gris Hannemann who, potentially, invented them to sell more copies of his books.

But they’re real now.

• Build fantastical, tragic settlements under threat from within and without
• Do your level best to defend them and keep the people inside alive and prosperous
• Watch, broken, as an emissary of a vast alien consciousness arrives and tears apart the walls like paper

A copy of Heart: The City Beneath is required to use the rules and advice in Sanctum.
