The Magnus Archives

He is described as ‘prematurely greying’ and ‘looking older than he is’ in “A Guest for Mr. Spider”, and he has many scars incurred from the hazards of his job. In conversation he is often rude and short-tempered at first, but meets kindness with kindness. After the events of "Eye Contact", John refers to himself only as ‘The Archivist’, having undergone a significant change. As of "Dwelling" and perhaps before, he is in a romantic relationship with Martin Blackwood. He is asexual.[5]
• Alexander J Newall as Martin Blackwood, an archival assistant at the Magnus Institute who obtained his job by lying about holding a degree in parapsychology. In "Colony" he is described as 'not exactly the smallest guy in the world' and in "The Masquerade" it is revealed that he looks exactly like his father. He is soft-spoken and generally gravitates away from social gatherings. As of "Dwelling" and perhaps before, he is in a romantic relationship with Jonathan Sims.
• Lottie Broomhall as Sasha James, an archival assistant at the Magnus Institute, mainly locating records that could set standard of proof for statements.

He assumed the role when John was promoted to head archivist, having worked with him previously in the research department. He is continually described as being exceptionally attractive. He has been in relationships with men and women, as revealed in "Across the Street" when he courts two file clerks. At first, he is kind and cocksure, but comes to resent his position within the Institute, becoming more cynical and angry in interactions with his coworkers, mainly John.
• Ben Meredith as Elias Bouchard, the Head of the Magnus Institute. The only notable visual description given has been his own assertion of having 'only two eyes'. He is initially dismissive of the concerns surrounding active paranormal activity within the Institute, but is quick to reveal some degree of intentionally withheld information when confronted.
• Evelyn Hewitt as Not-Sasha, a paranormal entity that wears Sasha James' identity. It lives in the tunnels under the Institute when not performing administrative tasks, and has a significant role in drawing John's attention to the paranormal happenings within the Institute's walls. It has issues with using technology.
• Sue Sims as Gertrude Robinson, the previous head archivist at the Magnus Institute. She was replaced by Jonathan Sims after going missing in March 2015. She is described as being 'in her fifties or sixties with reading glasses and grey hair in a tight bun'.

• Luke Booys as Michael, a manifestation of a paranormal power. Its appearance is flexible, but its base humanoid version is that of Gertrude Robinson's assistant, Michael Shelley, who was a tall man with straw blonde hair and a round face. It was bound to Michael as a part of a ritual. Its distorted version, the same appearance but thin and limp with hands as large as its torso, can be seen in mirrors. It both resides in and is a realm accessible only by a door of its own conjuring. It preys on people by luring them into its door and trapping them within an inescapable labyrinth. It was killed by and became Helen in "Another Twist".

Season 1 of the Magnus Archives ran from March 24, 2016 to October 13, 2016.

The eponymous Jonathan Sims is installed as the new Head Archivist of the Magnus Institute's Archives, his predecessor Gertrude Robinson seemingly presumed dead. As he attempts to digitize the supernatural statements, he finds that some statements can only be recorded on tape recorder as opposed to the preferred digital recordings.[7] Among these statements are mentions of paranormal books he calls "Leitners" because many of them seem to originate from a library that had belonged to a man called Jurgen Leitner.[8][9] He also records statements live from subjects, including Melanie King, a paranormal investigator who hosts a YouTube series called Ghost Hunt UK.[10]

Initially John is skeptical of the supernatural happenings detailed within each statement but eventually he begins to uncover connections between the statements suggesting that the dark forces and horrors described within them are real. Over the course of each recording, various characters make incidental appearances to speak to John, such as the Institute Head Elias Bouchard[9] and the archival staff, Martin Blackwood,[11] Tim Stoker,[12] and Sasha James.[13] In one particular episode, Sasha herself makes a statement regarding a supernatural being called Michael that seems at least slightly more benevolent than other supernatural beings that are mentioned.[14]

In particular, a woman named Jane Prentiss, a former New Age shop assistant, has become the host for a mass of parasitic worms that seem intent on attacking members of the archival staff, particularly attacking Martin,[11] and, eventually, attacking the Archives itself. In the chaos of Prentiss' final attack, Sasha dies at the hands of another supernatural being, but her death goes unnoticed as the supernatural being replaces her and assumes her identity. The body of Gertrude Robinson, the former Archive Head, is also found in one of the tunnels beneath the Institute, three bullet wounds in her chest.[15]

Notable Episodes:

• MAG - 1 - Angler Fish - Show debut streamed millions of times.

Season 2 of the Magnus Archives ran from December 1, 2016, to August 31, 2017.

In the aftermath of Prentiss' attack and subsequent death, John finds himself with a growing sense of paranoia. John is convinced that there is a greater conspiracy behind the murder of his predecessor Gertrude Robinson,[16] and he works alongside the police to investigate, most notably from Constable Basira Hussain.[17] John also begins to explore the tunnels beneath the Archives, convinced that someone is down there.[16] The other archival staff begin to worry for both John's safety and sanity, to which John only responds with suspicion. As John continues to distrust and investigate his coworkers, to the point of stalking and breaching of privacy, his archival assistants become more aggravated, Tim in particular though Martin shows more concern for John.

After taking a live statement from a woman named Helen Richardson, a real estate agent who claimed to be terrorized by a supernatural being, John finds himself confronted by the supernatural being in question, Michael. Michael implies that there are much greater forces at work and states that Sasha is "lying to him" before leaving and taking Helen with him.[18]

John continues his investigation of the tunnels and finds evidence of Sasha and an old man he's never seen before going into the tunnels.[19]

Later, Melanie returns to the Institute, stating that her YouTube crew has disbanded. She and John argue that the woman John knows as Sasha is actually "not Sasha".[20] This eventually raises John's suspicions and he finds more statements connecting a strange being called the "NotThem" that can replace people and a strange table that is sitting in the Institute's artefact storage.[21] He decides to take immediate action and destroy the table, but the creature impersonating Sasha explains that the table was actually "binding" them and then they directly attack John in their more monstrous form. John is eventually saved by the mysterious old man who'd been in and out of the tunnels: Jurgen Leitner, the previous owner of the library of paranormal books in various statements.[22]

In John's office, Leitner explains he'd been hiding in the tunnels since the destruction of his library in 1994, evading various monsters and people who sought to do him harm. He then explains his understanding of the entities behind the books (and creatures such as "Michael" and the "NotThem"): that they are manifestations of vast, powerful entities based on primal fears that exist just outside of human perception. He also relates that he believes that the Institute's Head, Elias, is the one who killed Gertrude, who Leitner had been working with to destroy the Institute, itself a place of power for one of the entities known as The Eye.

John steps out, overwhelmed with these revelations, at which point, Elias himself steps in, surprised but pleased to discover with whom Gertrude had been working. Elias then murders Leitner brutally with a metal pipe and leaves, not wanting to leave any loose ends. When John returns, he immediately flees from the bloody scene. The body is then discovered by Tim and Martin.[23]

Tim and Martin struggle to hold themselves together following the disappearance of their friend Sasha. The newly hired Melanie is acting increasingly erratic, and it is beginning to dawn on the whole team that they are all far too involved with the Archives to leave now, if they ever or even could.
