Ophelia MacDermothGregor's daughter, gifted with psychic abilities at birth.
- Blessed with Suck: While her psychic sensitivity is certainly useful, they can prove to be rather problematic and overwhelming when she picks up even the faintest vibrations.
- Catch-Phrase: "I must concentrate."
- Cool Old Lady: In the present day, she aids Bishop in finding out how the Elder Star was defeated.
- Deadpan Snarker: Rarely, but noticeable when she does.Ophelia: (flat monotone, after seeing Alvin Carter's corpse in the wardrobe) There's a skeleton in this closet.
- It Amused Me: She pretends to be senile to annoy her nurse.
- Missing Mom: Her mother was driven mad and institutionalized for the rest of her life. Ophelia never met her, except in a vision.
- The Ophelia: Played with. Despite sharing the trope's name and having strong psychic abilities, she's actually quite sane. However, she inherited her powers when her mother was driven insane.
- Psychic Powers: She frequently has visions that give her glimpses of the future and aid her in finding clues.
- You Gotta Have Purple Hair: In her younger days, just like her mother.
Dr. Gregor MacDermoth
Ophelia's father, and the chairman of the Department of Anthropology at Southwick University.
- Badass Bookworm: Is fluent in obscure and occult knowledge, which helps immensely in his quest to defeat the Great Ancients and their servants.
- Badass Grandpa: At 63 years old, he's still hunting the Great Ancients and their servants. Not to mention it was him that destroyed Shub-Niggurath with an incantation.
- Catch-Phrase: In The Miller Estate, he uses "Blast my light" and "Hell's bells" on a semi-regular basis.
- Guttural Growler: In The Stone Circle.
- Nice Hat: Wears one on his expeditions to St. George's monastery, and again to Stonehenge.
- Occult Detective: More so than either of his companions, his focus is primarily on finding hidden knowledge and collecting relics to help solve the mystery.
- Old Soldier: He's 63 years old, and dedicated his life to banishing the Great Ancients from the universe for good.
- Roaring Rampage of Revenge: Why he hunts the Great Ancients and their worshipers. His wife was driven insane on an expedition after witnessing a tribe summon Cthulhu.
- Agent Scully: Despite having personally witnessed many supernatural manifestations, he remains a skeptic.
- Badass Longcoat: In the second season, he wears a gray one.
- Badass Normal: Unlike Gregor, who's fluent in occult knowledge, or Ophelia, who is aided by her psychic powers, he's just a normal man. This doesn't stop him from killing or incapacitating several members of the Elder Star.
- Catch-Phrase: In The Miller Estate: "My detection equipment is infallible." Though notably, he only says this twice.
- Deadpan Snarker: Given his skepticism on the paranormal in a setting where its existence is well-established, it's only inevitable that he'll make the occasional sarcastic quip.Prescott: (after Ophelia shows him a sculpted head of a monster) Nice artwork.
- Empowered Badass Normal: When he wears the Amulet of Mnar, which protects him from being brainwashed by Brother Barnstable.
- Flat-Earth Atheist: Firmly refuses to believe in any supernatural experiences he faces.
- Genius Bruiser: He's big and strong, but capable of making his own technology to aid him. He's also debunked many frauds who claim to have witnessed paranormal activity. Though notably, he's more likely to use his wits than his strength to take out various threats he faces, with the one exception of his Traintop Battle with Brother Barnstable.
- Nice Hat: Also in The Stone Circle. It compliments his Badass Longcoat quite well.
- Occult Detective: A paranormal investigator who makes a career out of debunking frauds.
- The Witch Hunter: Not one himself, but he's descended from one of the executioners from the Salem Witch Trials.
The Elder Star
- Badass Baritone/Evil Sounds Deep: Has a very deep voice and is the leader of the Elder Star cult, hellbent on dooming the human race.
- Badass Longrobe: Wouldn't be a Cardinal without one.
- The Bad Guy Wins: Twice. First when the heroes activate the Duncan Creek node, then the Stonehenge node. However, it's implied that if the series continued, then he would have eventually been beaten at his own game.
- Big Bad: As the leader of the Elder Star, hellbent on world domination, this comes naturally. Though he shares this duty with Alicia Blackwood as of The Stone Circle.
- Card-Carrying Villain: He knows full well that the Great Ancients are pure evil, and willingly takes their side, believing that there is no real good in the universe.
- Everyone Calls Him "Barkeep": He's only ever called "the Cardinal". Although a book in the Miller Estate's library on the theory of Leys is written by one Cardinal Kardec, who may or may not be him.
- Evil Is Hammy: Of the Large Ham variety in the first series, but mellows out (slightly) in the second and becomes more of a Cold Ham.The Cardinal: (in one of Ophelia's visions) FOOOOOOL! Are you too dumb to understand my intentions? EVEN if you choose to close your eyes, YOOOOOOOOUUUU will have CHOSEEEEEN!
- Evil Old Folks: Around the better part of 700 years old, is immensely powerful, and wants to release the Great Ancients upon the world.
- Faux Affably Evil: He congratulates the heroes on dispatching the Guardian and Shub-Niggurath and thereby activating the nodes, calling them "partners" and "friends", thanking them for their unintentional help. However, his tone is condescending and he has every intention of restoring the reign of the Great Ancients for his own benefit.
- It's All About Me: Seemingly. He doesn't really have much other motivation for wanting to bring the Great Ancients back other than for his own empowerment, despite knowing full well what it would mean for the rest of humanity.
- Knight of Cerebus: The series is already undeniably dark as it is. But whenever he shows up, things get a hell of a lot worse and nightmarish, changing the narrative from the standard Lovecraft Lite where the good guys seemingly triumph over the Great Ancients and their servants into a Cosmic Horror Story where their efforts only helped hasten the doom of humanity.
- Manipulative Bastard: Oh, so much. Everything the trio and the gods did to try and beat him at his own game was all according to his plan.
- Omnicidal Maniac: His goal is to unleash the Great Ancients upon the world.
- Puny Humans: "Poor little creatures ..."
- Really 700 Years Old: At least 700 years old.
- Sinister Minister: There's a reason he's called the Cardinal.
- Third Eye: Has one painted on his forehead in the first season, and in a couple episodes of the second. It's strangely absent in the final episode, though.
- Touched by Vorlons: He is thought to have tapped into the Great Ancients' power to some extent, which would explain his own power and his advanced age.
- Xanatos Gambit: It doesn't matter what course of action the heroes take, or if the new gods are assisting them. Thus far, he's beaten the heroes both times, although his winning streak apparently didn't last forever.
Alicia Blackwood, aka Baroness Alicia Vonaburg
- Asshole Victim: She's been playing with the heroes throughout the whole story, and is hellbent on world domination. One can be forgiven for thinking that she deserved to die gruesomely.
- Beware the Nice Ones: She is kind and hospitable to her guests, even looking after Ophelia while she recovers from her journey through time. This, of course, is all a ruse.
- Big Bad: Of The Stone Circle, although she shares this duty with the Cardinal.
- The Chessmaster: Under the guise of Baroness Alicia Vonarburg, she invited Ophelia, Gregor, and Prescott to London for Ophelia to play at the London Philharmonic Society, leading them to find the remains of Shub-Niggurath scattered across England. This was all part of her plan to awaken and enslave the demon and assume the mantle of the master of the Elder Star.
- The Ghost: We only get to read her letters and hear her voice on a phonograph. That is, until she's revealed to be Baroness Vonaburg.
- HeelFace Door-Slam: In The Stone Circle, she turns against the Elder Star and asks Prescott and his companions to find the relics, and dies shortly afterwards. Or so we're lead to believe.
- I'm Melting!: How she dies.
- Ouroboros: It's on her tiara.
- Rewarded as a Traitor Deserves: After awakening and trying to enslave Shub-Niggurath, she melts and her blood feeds the beast.
- Rich Bitch: Comes with being a baroness and a member of the Elder Star.
- Shout-Out: Her surname is likely one to Algernon Blackwood, who served as a major inspiration to Lovecraft's works.
- The Starscream: She wants to overthrow the Cardinal.
- You Gotta Have Purple Hair: A darker shade of purple than Ophelia's.
- Badass Longcoat: Black trench coats.
- Brown Note: Simply revealing the Elder Sign in their hand will instantly drive someone irrevocably insane.
- Dark Is Evil: They wear black trench coats and hats, with most of their facial features obscured. And they're members of the dangerous Elder Star cult.
- The Faceless: Their facial features aren't discernible, except their eyes.
- Good Smoking, Evil Smoking: One of them is encountered smoking a cigarette on the boat.
- Knife Nut: Brother Barnstable chases Prescott to the top of the train with a knife.
- Nice Hat: Like Prescott, it compliments their trench coats.
- Prophet Eyes: White sclera with no pupils or irises.
- Put on a Bus: After two episodes of confronting them, they are never seen again. However, since one is last seen being knocked overboard into the River Thames by Prescott and the other is left stranded and unconscious on a decoupled train car somewhere in the countryside, it's very easy to excuse why they aren't seen again.
- Wake-Up Call Boss: Maybe not really bosses, but in case you were getting used to just avoiding aimless clicking, they came in and became the first physical threat you have to face.
The Great Ancients and servants
The Great Ancients in general:
- Adaptational Villainy: H.P. Lovecraft portrayed the Great Old Ones as not so much evil as they are beyond simple morality as we know it. Here, they are stated to be truly malevolent, and their only goal is to restore their reign of chaos, and of terror.
- Adaptational Wimp: The Book of Yhe says that the Talisman can be used to enslave or kill them, whereas they are usually portrayed as either being Nigh Invulnerable or having Complete Immortality.
- Always Chaotic Evil: A good deed done by the Great Ancients has yet to be shown.
- Devil, but No God: The new gods that had defeated the Great Ancients don't have as much earthly influence as them.
- Eldritch Abomination: It goes without saying. After all, theyre an interpretation of the Trope Codifiers.
- Evil Is One Big, Happy Family: Averted. They seem to have no qualms with sending their own out to Earth if it means a hastening of their return.
- The End of the World as We Know It: What else would happen if a vengeful race of Eldritch Abominations were unleashed upon the earth?
- Greater-Scope Villain: None of the series' events would have happened if it weren't for them.
- Primordial Chaos: In the beginning, only chaos existed
- Sealed Evil in a Can: Most of them are trapped somewhere outside time and space as we know it, while Cthulhu slumbers in the city of Rlyeh and Shub-Niggurath had his dismembered remains scattered across England.
- Adaptational Wimp: Unlike the cloudlike abomination s/he is often portrayed as that can spawn an endless number of its horrible Thousand Young at will, this interpretation of Shub-Niggurath is limited to swatting and headbutting, and is subservient to (and can be destroyed by) the Talisman of Yhe, and an incantation. Not to mention that he's painfully easy to beat.
- Artifact of Doom: His dismembered body parts. When the monks tried to bury them on holy grounds, they were almost always met with a catastrophe of some sort.
- Gender Flip: Many authors after Lovecrafts time depict Shub as female. Thats not the case here.
- Good Wings, Evil Wings: Evil, of course.
The Guardian of the StoneA servant of the Great Ancients, responsible for the disappearance of many of Duncan Creeks denizens.
- Blob Monster: Although it sometimes assumes a more humanoid shape.
- Eldritch Abomination: Like its masters, albeit a lesser one.
- Generic Doomsday Villain: Not much is really known about it other than that it's a powerful and dangerous monster that's responsible for a rash disappearances in Duncan Creek.
- The Heavy: It's responsible for the events of The Miller Estate, and is more prominent than the real Big Bad of the series, the Cardinal.
- Humanoid Abomination: It sometimes looks roughly human in appearance, although it's still really obvious that it's not.
- More Teeth than the Osmond Family: If the game over screens for The Miller Estate episode 4 are anything to go by, it has rows upon rows of sharp teeth.
The ShadowAn unnamed creature that assumes a shadowy form. It appears in a few episodes with every other pointless click of the mouse, and will either drive the player character insane or kill them if they click in the wrong place too many times.
- Eldritch Abomination: Assuming that it doesn't devour you outright, it's too horrific to be comprehended, as it can drive Prescott mad with a single glance at what's likely its true form in episode 1 of The Miller Estate. It also appears to have some sort of Reality Warper abilities.
- Nothing Is Scarier: You never see its true form, though one can assume from their reactions that the protagonists do.
- Ultimate Evil: All that can ever be seen of it is its shadow.
- The Unfought: It cannot be fought or killed. You just have to be cautious about clicking aimlessly.
A young man who comes to visit Ophelia for guidance in the nursing home where she resides.
An elderly museum curator and an old friend of Gregor.
Ophelias mother and Gregors widow.
- Go Mad from the Revelation: She witnessed an African tribe summon what is implied to be Cthulhu, and was so traumatized that she lived the rest of her days out in a mental hospital.
- The Lost Lenore: To Gregor.
- The Ophelia: Ironically, more so than her daughter.
- You Gotta Have Purple Hair: Just like her daughter.
Ophelia's ornery nurse.
- Fiery Redhead: Has red hair and a bad temper.
- Jerkass: She's incredibly rude and easily annoyed by Ophelia's (supposed) insanity.
- Lack of Empathy: Regardless of Ophelia's Obfuscating Insanity, you'd think someone of Janet's profession would be a bit more sensitive to people suffering from mental illness.
The Miller villa's last tenant and a penpal of Alicia Blackwood.
The New Gods/The Elder Gods
Benevolent deities who fought the Great Ancients and banished them beyond the frontiers of the universe.
- Adaptational Heroism: The Elder Gods, according to Lovecraft, were really no better than the Great Old Ones themselves. But here, they're allies to the human race, and want to save them. Justified, because that's August Derleth's vision of them, and his interpretation of the Cthulhu Mythos is especially prominent in this series.
- Big Good: They leave artifacts scattered throughout time to help humanity to defeat the Great Ancients.
- The Ghost: They're never encountered in-game, and are only spoken of or represented by idols.
- Nice Job Breaking It, Hero!: As with just about everyone in the game's universe, the aid they offer is completely compatible with the Cardinal's schemes.
