The Circle Undone

Death Is Only the Beginning

“The hidden cults to which these witches belonged often guarded and handed down surprising secrets from elder, forgotten aeons; and it was by no means impossible that Keziah had actually mastered the art of passing through dimensional gates.”
– H. P. Lovecraft, The Dreams in the Witch House

The Circle Undone is a campaign for Arkham Horror: The Card Game for 1–4 players. The Circle Undone deluxe expansion contains a prologue scenario, “Disappearance at the Twilight Estate,” and two full scenarios: “The Witching Hour” and “At Death’s Doorstep.”
These scenarios can be played on their own or combined with the six Mythos Packs in The Circle Undone cycle to form a larger nine‑part campaign.

Additional Rules and Clarifications

Tarot Slot

Tarot slots are a new type of asset slot introduced in this expansion.
The following symbol indicates that an asset fills a tarot slot:
As with other slots, tarot slots limit the number of asset cards of that slot type an investigator is permitted to have in play simultaneously.
By default, an investigator has only one tarot slot available. All other rules governing slots apply to tarot slots, as usual.

Haunted

Haunted is a new ability that appears on some locations. Each time an investigator fails a skill test while investigating a location, after applying all results for that skill test, that investigator must resolve all “Haunted –” abilities on that location.
A location is “haunted” for the purposes of other card effects if it has at least one “Haunted –” ability (printed or otherwise).

Alert

Each time an investigator fails a skill test while attempting to evade an enemy with the “alert” keyword, after applying all results for that skill test, that enemy performs an attack against the evading investigator. An enemy does not exhaust after performing an alert attack. This attack occurs whether the enemy is engaged with the evading investigator or not.

Prologue Investigators

The four investigator cards depicted here (Gavriella Mizrah, Jerome Davids, Penny White, and Valentino Rivas) are marked with the Disappearance at the Twilight Estate encounter set icon and can only be used in the prologue for The Circle Undone. They cannot be used in other scenarios. Keep them with the rest of the scenario cards for Disappearance at the Twilight Estate, and do not integrate them into your collection of player cards.

Story Cards

Story cards are a new cardtype in The Circle Undone campaign. These cards serve as an avenue for additional narrative and typically appear as the reverse side of another scenario card. When you are instructed to resolve a story card, simply read its story text and resolve its game text.

Joe’s “Hunch Deck”

As a private eye, Joe Diamond has learned to follow his instincts, and therefore he has a separate hunch deck, which is constructed during step 4 of the setup of each scenario. The cards in this hunch deck are chosen from Joe’s 40-card deck and therefore count toward his total deck size. With the exception of these setup instructions, all references
to Joe’s “deck” refer to Joe’s standard investigator deck and not his hunch deck. Joe’s hunch deck has no discard pile; cards from your hunch deck are discarded to your standard discard pile when played.
