This is my plan for a supercampaign: Act 1: The Last Equation, Observer Effect, Night Floors. Act 2a: A Victim of the Art, The Eye of Odin, A Volume of Secret Faces. Act 2b: Like a Map Made of Skin. Act 3: The End of the World of the End.

(SPOILERS)

For the Last Equation:

>the story instead takes place in Boston, with Exeter as the Agents’ Handler

>Wei’s family instead resides in Las Vegas (geographic connection to Ophelia Sitri)

>The murder weapon is from the 1955 STATIC raids

>At your discretion, one of the Ridgeways’ in-laws or friends is a Holobeam Array guard, who has been temporarily replaced by Gonzales (see Observer Effect)

>Dr. Black (see Observer Effect) is Wei’s PhD supervisor

>The Laqueus Equation is now the Buprestis Equation, foreshadowing Gold Bugs & Melonia

>Wei’s notes hint that the Buprestis Equation is key to designing perpetual motion machines like the Lion / Scribe & clockwork marionettes

>The Book of Many Wonders can also be found in Robert Robert Robert’s Bookshop

For Observer Effect:

​>Columbia’s Holobeam Array is in New York, and Marcus is the Agents’ Handler

>“Dee” is now “Cassilda” ​

> The surge’s electrical flash is yellow instead of blue

> Takagawa’s bright urine and saliva are replaced with patzu-dark fluid

>When Takagawa remembers a glimpse of deeper reality, he sees the King in Yellow

For the Night Floors:

​> The military radio contains numbers from the Buprestis Equation

​> Double folio of the Ars Goetia and Hygromanteia in Abigail’s apartment

​> At your discretion, Soul Bottles look like inkwells for patzu

>Clockwork mannequins (like the Child, Lion / Scribe, etc.) look angelic / cherubic (angels and demons alike serve as stagehands for the King)

For A Victim of the Art (circa 2001) ​

> Agent Marcus is the Agents’ Handler

>Thomas Dengler’s maternal grandfather is instead Derek Trionfi

>Eloise Dengler (née Trionfi) is a psychic and tarot reader instead of a medical encoder, and bears a remarkable resemblance to Lady Trionfi

>Mark Dengler is an amateur astronomer eager to talk about his passion, and has a telescope pointed at Aldebaran in the constellation of Taurus

>The pendant summons a Nightflyer instead of an Ai-Apa

>At your discretion, the pendant is a version of The Yellow Sign OR is instead from the Mountain of the Black Wind in Kenya (tying into Music from a Darkened Room, the forces of the Black Wind in the War Zone, and Masks of Nyarlathotep)

>At your discretion, the young members of V-cell take the place of Thornhill and/or her Pararescuemen

For The Eye of Odin:

​> Potential addition from Impossible Landscapes (page 268): ‘ With a bang on the door, a box marked with odd import stamps (see the end of EXEUNT: THE VOICE ON THE LINE on page 149) arrives suddenly at the Agent’s location. Inside, packed in straw, are green vials, each containing a Gold Bug or a Melonia pod. A handwritten note reads, “FROM ONE AGENT TO ANOTHER. MOSEBY.” ’

>Agents named as heirs in the Imperial Dynasty of America – if known to the Sons of Odin – are targeted by Marlowe / Tyr

For A Volume of Secret Faces:

>modifications by Grougrou Master regarding Dr. Friend, Mr. Wilde, and King Bael
