Great Old Ones

Nyarlathotep: The Big Bad. Also known as The Liar, The Liar From Beyond, The Crawling Chaos, Nephren Ka, the Black Pharaoh, the God with a Thousand Forms, the Mouth, the Thing With A Thousand Mouths, and the Herald of Azathoth. Nyarlathotep is a trickster god with thousands of forms, called Masks. 

In his Mask as the Thing With A Thousand Mouths, Nyarlathotep manifests in the form of mouths. Minor Mouths are the side of an ordinary mouth and appear on walls, floors, or the bodies of his followers; they can hiss and spit acid. Major Mouths appear on walls and are larger than a human being; they drool Nectar. Nectar is a drug which makes you sharper and cleverer and harder working and more ambitious and more insightful and generally on top of the world. It is addictive.

The Mouths and some cultists speak the Tongue of Lies, a nonhuman language that rends the sanity of those who hear it. 

In His Mask as Nephren Ka, Nyarlathotep has been regularly visiting Zoe's acrobatics performances and making cryptic, ominous, and plausibly hallucinatory visitations. 

Gol-Goroth: Ramon Echavarria told the outer circle of the cult that they worshiped Gol-Goroth, but this is probably wrong. 

Azathoth: Also known as The Watcher (only by the PCs) or the Blind Idiot God. A giant terrifying Eye that Zoe had a vision of; Nyarlathotep is his Herald. 

Cult Leaders and Second-In-Commands

Samson Trammel. Former leader of the Los Angeles cult. Smug, condescending, and the walking human embodiment of Dunning-Kreuger. Abusive foster father of Lacie and Oswald Ferrier. Has achieved the dubious honor of having raped every single person that Oswald cares about even if you make the implausible assumption that he cares about himself. Voted "most deserving of being devoured by a Mouth" fourteen years running. 

Captain Walker. Former second-in-command and current leader of the Los Angeles cult. Knows Mordred's name. 

Savitree Sirikhan. Current head of the Bangkok cult. Terrifyingly good at her job.

Daniel Lowman. Second-in-command of the Bangkok cult. Best known for paying the cult's network of informers. Savitree's boyfriend, who is from Lev's perspective both unfairly pretty and unfairly monogamous. 

JB. Current head of the Mexico City cult, which has been producing too little Nectar but has been producing some very interesting mind-control music. ABSOLUTELY going to do his job AS SOON AS his band gets their big break. You just don't BELIEVE IN HIM. He is FOLLOWING HIS DREAMS. 100% has ADHD. 

Cristobal de la Luz. Birth name Cristobal Vega. Like all Chrises in a cosmic horror setting, absolutely up to something extremely normal and good that 100% does not involve destroying the world even one little bit. JB's boyfriend. Weirdly short and has a high voice? Who knows what's up with that. 

Montgomery Donovan. Head of the Malta cult. Nectar production spiked in February 1934. Apparently "understands with the bitter black dregs of wisdom" that "with magic, the greater the sacrifice the greater the reward," which is literally zero percent ominous. 

Significant People of Investigators

Oswald Ferrier

Lacie Ferrier. Sister who was kidnapped by Samson Trammel and convinced to join the cult as his second-in-command/lover/daughter. Her current whereabouts and fate, given Samson's death, are unknown and Oswald prefers not to think about it.  

Lev Aarons. His boyfriend, with whom he shares certain otherwise unique experiences like being abused by Samson Trammel and having a loved one who has joined the cult because it is so beautiful, and with whom he is vaguely groping towards some concepts such as "it is bad when people rape me."

Mordred Orkney

Gale Dulac. His best friend, who is a devout Catholic and Known Very Good Person. Mordred is a little bit in love with him and will never admit this to anyone.

Agravaine Orkney. His older half-brother, known best person to help you hide the bodies while complaining that really you should not be murdering anyone in the first place. 

Morgan Marsh. His aunt, who told him the occult existed and immediately vanished without a trace. 

Lev Aarons. Mordred rescued him from an asylum and considers himself responsible for his well-being. Fortunately, Lev is also really cute and enjoys infodumping about anthropology. Mordred has some conflicted feelings about this fact.  

Zoe Aletheia

Ralph Haas. Her best friend, an antiquarian who collects strange and unusual items. When she's in New York she swings by his place to do erotic photography. She feels like she has to stay away from him to keep him safe.

Anemone Silverstring. Her rock and a source of sanity in the world. 

Anemone Silverstring

Thomas Octavian Silverstring. Anemone's younger brother. She worked hard to take care of him after the death of their parents.

Zephora. An old woman of unknowable age who did fortune telling and magic tricks near the circus before her health began to deteriorate. Currently lives with her grandson in NYC.

The Librarian. Anemone's monstrous childhood imaginary friend. It eats stories. If you're helpful it will tell you some.

Magnificence. Her trained squirrel monkey. He gets treats if he brings her interesting things.   

Other Important Characters

George Ayers. Former boyfriend of Lev and current corpse. Member of the Inner Circle of the 1924 cult. In 1924, went to Dallol for a dig to find out more information about the Mouth and disappeared. Presumed dead. 

Ramon Echavarria. Former abusive boyfriend of Lev and current corpse. Film producer and original founder of the cult, who died tragically in 1924 when his ritual to summon Nyarlathotep was interrupted by a crew of meddling investigators. Fascinated by the beauty of the Mythos.

Janet Winston-Rogers: The funder of the expedition. Daughter of one of the men who attempted unsuccessfully to stop the cult from summoning Nyarlathotep.
