After the success of Dark Horse Comics and Studio Hermitage’s comic series Our Brilliant Ruin: Horror at Crane Mansion, the original TRPG rulebook for the gilded-age-inspired, eldritch-horror-themed tabletop role-playing game is set to arrive from Dark Horse Books. Our Brilliant Ruin TRPG Rulebook is a hardcover edition of the guide to running your very own role-playing game within this carefully crafted upstairs-downstairs drama-filled world.

Our Brilliant Ruin is set in the Dramark, a place where the last fragile remains of society burn with excess and intrigue in the shadow of a dying world. The Ruin, a preternatural force befouling everything it touches, has ravaged geography and culture alike, wreaking destructive havoc and transforming both people and animals into monstrous creatures. With the world plunged into darkness, how will you spend the time you have left?

Dive into the dramatic world of Our Brilliant Ruin with the official tabletop role-playing rulebook, created by Studio Hermitage and now available from Dark Horse Books. This full-color hardcover tome will be your guide to the Dramark, its inhabitants, and the horrors that lurk in its shadows as you launch your next saga.
