The Magnus Archives

• Jonathan Sims as Jonathan "Jon" Sims, the head archivist at The Magnus Institute, a title with which he announces himself at the beginning of each statement he records. 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", Jon 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 on some varying degree of the asexual spectrum.[4]
• 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. She is described as tall and having long hair and glasses. In "Human Remains" she was replaced with by an entity known as 'Not-Sasha', which wore her identity with a different body.

He assumed the role when Jon was promoted to head archivist, having worked with him previously in the research department. He is continually described as being exceptionally attractive.

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 Jon.
• 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 the administrative tasks, and has a significant role in drawing Jon'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 'an elderly woman in her fifties or sixties with reading glasses and grey hair in a tight bun'. She appears in some episodes in past recordings of statements as Jon and the other assistants work to understand her role at the Institute. Her demeanor is brusque and she is very serious about her work.

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 with 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 24th, 2016 to October 13th, 2016.

The eponymous Jonathan Sims is installed as the new Head Archivist of the Magnus Institute's Archives. Initially he is skeptical of the supernatural happenings detailed within the statements, though eventually Jon uncovers connections between the statements suggesting that the dark forces and horrors described within them are very real indeed.

Specifically, 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 and, eventually, the Archives themselves.

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

In the aftermath of the attack Jane Prentiss mounted against the Archives, suspicion is everywhere. Jon is convinced that there is a greater conspiracy behind the murder of his predecessor Gertrude Robinson, and he investigates alongside the police to attain answers. The other archival staff begin to worry for both Jon's safety and sanity.

Other pieces begin to move between the mysterious "Powers", and Prentiss' attack has left the Archives significantly more vulnerable than any of its staff know. Jon has spotted a figure moving within the Archives at night, and Tim is struggling with his scars, mental and physical. At least "Sasha" seems unchanged...

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.

As a wanted man, Jon goes from hiding with his friends, to being kidnapped by a sinister circus, to travelling the world trying to piece together what information his predecessor had put together on the mysterious ritual of "Unknowing"...
