Overview in 60 Seconds

Arkham Horror: Secrets of the Order is the third major expansion for Arkham Horror Third Edition, published by Fantasy Flight Games in 2021. It brings one of the Arkham Horror Files universe's most iconic antagonists to center stage — the Order of the Silver Twilight, Arkham's secretive and dangerously powerful secret society led by the enigmatic Carl Sanford.

What makes Secrets of the Order stand out among Arkham Horror 3rd Edition expansions is the introduction of traversal to other worlds. For the first time in this edition, investigators can pass through thresholds into alternate dimensions — the ghostly heights of French Hill and the monstrous Underworld — adding a vertical dimension to the investigation that fundamentally changes how scenarios unfold.

Players who experience Secrets of the Order consistently describe the moment investigators first step through a threshold into the Underworld as genuinely unsettling — the rules shift, the environment becomes alien, and the cosmic horror of Lovecraft's universe suddenly feels much closer than it did in Arkham's familiar streets.

What Does Secrets of the Order Add?

How Does It Play?

Secrets of the Order uses the same Arkham Horror 3rd Edition engine — investigators work cooperatively to complete scenario objectives while managing mythos cards that spawn monsters, advance doom, and trigger narrative events. What's new is the threshold system: certain locations now serve as gateways to other dimensions, and passing through them transports investigators to entirely different boards with their own encounters, monsters, and rules.

The three new scenarios are tightly designed around the Silver Twilight theme. One has investigators chasing ghosts through the storied French Hill neighborhood. Another sends them into the Underworld itself — a realm of monsters and madness beneath Arkham's streets. The third brings the Order's conspiracy to a dramatic confrontation with Carl Sanford himself.

The four new investigators are among the most interesting in the 3rd Edition lineup. Winifred Habbamock's agility-based playstyle and Agatha Crane's parapsychological abilities both feel authentically tied to the expansion's themes — and both provide meaningful new options for experienced players looking to vary their investigator combinations.
