Dare to cross the threshold!

The restless spirits of the dead scream and ghouls roam the streets at night. In abandoned places, portals open between our world and the horrible Underworld, and in the vicinity of the infamous French Hill, the Order of the Silver Twilight weaves its own plan in the hope of even greater power.

Board game Terror in Arkham In the Secrets of the Order add-on, they ventured into new worlds! Four new detectives confront the ghosts of Arkham's past with new scenarios, map tiles and hundreds of cards introduced in the expansion.

Only an add-on, not a stand-alone game.
