Season 1

In 1991, while filming a short film, a cameraman phases into the ground, finding himself in a strange dimension of infinite corridors. While examining graffiti on a wall, a creature that begins to pursue him. The cameraman escapes to a lower floor, experiencing various architectural anomalies before being led back up. He is shortly after pursued yet again. He hides from the Lifeform in a narrow wall gap leading to a steep slope, at which point the creature charges at him, grabbing him and causing him to drop his camera down the chute, which phases back into reality and falls from the sky in 1996.

An opened .tar archive displays images of the Complex and redacted personnel.

On 2 July 1988, the Async Research Institute conducts the third test of their "Low-Proximity Magnetic Distortion System". A synthesized voice explains that in April of that year, a press conference was held where the vice director of Async, Ivan Beck, stated the goal of the project was to offer a cost-effective solution to all future storage and residential needs and save millions of dollars in property management and construction.

On the 17th of October 1989, Async performs the sixth test of the Low-Proximity Magnetic Distortion System. The experiment results in the opening of a gateway into the Complex, but it coincides with the 1989 Loma Prieta earthquake.

3 February 1990. Reported missing person cases begin to skyrocket shortly after the opening of the Threshold (the name given to the gateway created by Async in "First Contact"). While on a routine expedition, several Async employees discover a dead body sitting against a wall covered in a dark mold-like growth.

5 February 1990. An autopsy is conducted on the body found in "Missing Persons". The medical examiner determines that growth is a malignant form of hay bacillus. The examiner asks Ivan Beck where the body came from. The scene then suddenly cuts to a TV that flashes through numerous images before settling on the Threshold, with the sun overlaid on top.

1 March 1990. Async employee Peter Tench gets separated from his expedition group while investigating strange noises. After seeing his group vanish in front of him, Peter begins desperately searching for them, but he finds a dark, small room that features the facade of a house on the other end. He finds his way back to the entrance only to find an observation room that was absent when he initially entered. He accesses the room, sounding an alarm in the process.

5 March 1990. Async sets up motion-activated cameras in the Complex. A compilation video is made from all available recordings. The first clips are inconspicuous, featuring employees passing between pillars, the Threshold barrier closing, and microphone failure. The final recording catches a dark mass peering from behind a distant wall.

10 May 1982. A test of the "Low-Proximity Magnetic Distortion System" is conducted at the Oak Ridge National Laboratory.

6 May 1990. During a Complex expedition to a room with pits on the ground, labeled 14D, human voices lead Marvin to encounter a creature that begins to chase him.

Higher-ups at Async review the footage recorded by Marvin in "Pitfalls". Startled by the existence of hostile life in the Complex, they seal off access to the portion of the Complex that leads to where the lifeform was encountered.

Black and white highway surveillance footage shows a car disappearing into the road.

8 May 1990. Async proposes plans for the potential commercialization of the Complex. A meeting with the head of the Department of Energy, James Watkins, is abruptly interrupted when a distressed Peter Tench, revealed to have traveled forward in time, finds his way back to the observation outpost.

Over a phone call, Async supervisor Clyde questions Ivan Beck about Peter Tench, who had been recovered from the Threshold outpost following "Presentation".

19 August 1995. A girl who fell into the Complex through the floor of her garage finds large rooms, furniture with unusual proportions, structures in a state of disrepair, indoor pools, and a home with a painting where a creature will begin to chase her. She is eventually cornered in a room before glowing green cracks form in the walls around her.

A compilation of inconspicuous VHS recordings and pictures are shown before attention is given to painting in the background of one of the photos, which is the same one seen in "Found Footage #2".

25 May 1990. Async reopens access to room 14D. Three researchers, including Marvin Leigh and Mark Blume (who is now armed with a shotgun), are sent out to assess the room leading to room 14D, where they are then suddenly ambushed by a man who Marvin recognizes to be Peter Tench. Peter, holding the team at gunpoint, reveals that Async faked his death, lamenting that his family thinks he is dead. Mark requests armed assistance from the team in the other room, before being shot by Peter.

After shooting Mark Blume, Tench flees and exits the premises of the facility. The next day, Async holds a meeting where they provide context to the events that happened the day prior. It is revealed that after escaping the facility grounds, Tench was found dead, seemingly from falling and bashing his head on rock. The video ends with brief flashing images and a phone ringing in an empty room.

2 August 1972. A machine system experiences a power overload. A green glow gradually fills an office room. Attention is given to a document clipped to a bulletin board, which displays the signature of Ivan Beck.

14 November 1989. Roughly a month after the events of "First Contact", Async employees remove a ceiling tile and a fluorescent troffer light from the Complex, with several noting the apparent absence of an external power supply to the light. Dr. Julia Meisner reports the preliminary results of the analysis.

A man, Ravi, falls into the Complex after investigating a noise coming from his basement. Ravi navigates the labyrinthine network of rooms and halls until finding himself in a dark disheveled room where an unknown creature begins to pursue him. Ravi runs, crossing a skywalk that overlooks a red-lit city before continuing further into the Complex. He uses a radio transmitter to call for help when, after investigating radio chatter, a humanoid figure darts towards him; Ravi barely escapes. Later, Ravi discovers a house placed in the middle of a large room. Inside, he hears a man speaking on the other side of a wall. Both try to look for each other when they realize that neither can see the other. An unknown amount of time later, a defeated Ravi talks to the dying camera, stating he has forgotten what the sky looks like.

29 May 1990. Following Tench's death, Marvin and George Levy debate the events; Marvin suspects that Peter was murdered, while George remains skeptical, persuading Marvin to take time off. Researchers return to Room 14D to document the room Mark found. George, who is now handling the camera, records stretched wallpaper, irregular floor depth, and furniture phased into the walls and flooring.
