Return to The Scarlet Keys

The Secret War has grown wider, stranger, and more dangerous. Scarlet Resurgence expands The Scarlet Keys campaign with new keys, new factions, expanded travel, and fresh ties to both classic and recent Arkham Horror lore.

Upcoming: Soon?

A New Beginning

The campaign offers a second Prologue, reminiscent of The Miskatonic Museum: a daring heist in which the enigmatic Red-Gloved Man steals the deadly Plague Stone after Ursula Downs returns from her Amazonian expedition. From there, the globe-spanning investigation spirals into ever more perilous encounters. You can now start your Campaign in Arkham, or in London.

New Keys of Power!

Resurgence unveils 11 additional keys, drawn from across the Arkham mythos:

The Supernal Prism (Call of Cthulhu LCG)
The Plague Stone (Call of Cthulhu LCG)
The Key of Ys (Aconyte: Song of Carcosa)
The Silver Sword (Aconyte: Song of Carcosa)
The Mask of Rakinui (Call of Cthulhu LCG)
The Xiamen Bi (Aconyte: Secrets in Scarlet)
The Coronal Prism (Aconyte: Secrets in Scarlet)
The Sextant (Call of Cthulhu LCG)
And more…

Each brings new paracausal risks and rewards into play.

New Faces in the Red Coterie

The roster of the Coterie members expands with two official members:

Monsieur Cinabre: a crimson-clad mastermind with an impossible library.
The Crimson Cavalier: the masked idealist of Venice, wielder of the Silver Sword.

Tuwile Masai and Abarran are fleshed out a bit more in the campaign.

Expanded Files and Secrets

The Foundation files and communiqués released outside the core game are now fully integrated. Players also gain access to an expanded Codex—a growing archive of interlinked entries that evolve across the campaign. It tracks all Coterie members, fresh leads, and paracausal phenomena, offering even more choices and branching paths.

New and Integrated Scenarios

Standalone Arkham Horror LCG classics are woven directly into the Scarlet Keys world tour:

Fortune and Folly
The Midwinter Gala
Curse of the Rougarou
Murder at the Excelsior Hotel
Guardians of the Abyss (set in Cairo, tied to Monterrey Jack’s brush with the Supernal Prism)
Film Fatale

Brand-new global scenarios expand the map. They all are based on existing classic AH LCG scenarios:

Shanghai: Secret societies, Lily Chen’s past, and the Jade Emperor’s curse (based on Threads of Fate).
Kathmandu: The mystery of Aliki Zoni explored, (based on To the Forbidden Peaks).
Paris & Venice: A Carcosan masque of swords, masks, and fate, with Cinabre, the Cavalier, Mr. Lapp, and new outcomes for Alessandra Zorzi (based on A Phantom of Truth, The Pallid Mask and War of the Outer Gods).
Amazonia: Ursula Downs’ legacy with the Plague Stone in the deep jungle (based on The Untamed Wilds).
Arkham (I): A Midnight Masks–style pursuit involving Eryn Cochwyn, Marcus Jamburg, the T’tka Halot, and the Mask of Rakinui (based on The Midnight Masks).
Arkham (II): A showdown between Commissioner Taylor and Ryan Davenport over the Coronal Prism (based on At Death’s Doorstep).
Antarctica: Dyer’s expedition closely monitored by The Foundation (based on City of the Elder Things).

The Black Chamber and The Outsiders

The Black Chamber emerges as a rival to both the Red Coterie and the Foundation, its ties to Cinabre and the Crimson Cavalier revealed. The Outsiders step further into the light, with Virgil Gray himself appearing at last to blur the line between fiction and truth.

The Outsiders related plots are also fleshed a bit more. I always felt like the Dr. Irawan arc was the most disconnected of all. That's why I tried tying the Dr Irawan arc to at least one scenario, as part of the many new ways you have to hop around the map.

New Ways to Travel

Investigators can cross the globe with greater freedom:

A new scenario aboard the Trans-Siberian and Orient Express (based on Essex County Express).
Consternation on the Constellation (by MythosBusters’ Ian Martin), adding ocean travel to the campaign.

New locations (Kingsport, Antarctica, Paris, Amazonia) and new scenarios in existing locations (Arkham, Shanghai, Kathmandu, San Francisco)

Green Destinations

They now have a slighlty different meaning now that I've included a fair amount of standalones in the Campaign.

New Ways to Travel

You have certainly notice some rail station, port and rail tracks iconography on the map:
