== Biography ==
=== Early life ===
Around 2018, a couple of software developers, named David and Jane, created thousands of simulations filled with sapient simulated humans. Larry McBain, presumably with memories of a full life, was created in a simulation of Los Angeles in the late 1990s. By 1999 in the simulation, McBain was a detective in the LAPD.
=== The Thirteenth Floor ===
Around June 18th, 2024, David, who had grown increasingly delusional and murderous, swapped minds with Douglas and used his body to murder Hannon Fuller, a simulated human who had created another simulation within the 1999 simulation, and was on the verge of discovering the truth of his own world. Douglas woke up the next morning with no memory of the previous night, finding his clothes covered in blood, but Detective McBain already discovered the body outside the bar. Douglas was the police's first suspect, as he had the most motive to kill Hannon due to Hannon listing him as the heir to the company and his fortune. McBain and another detective, Zev Bernstein, met Douglas in the station, and Douglas took McBain and Bernstein to Fuller's apartment within the company's building. There, they were met with Jane Fuller, who had entered the simulation under the guise of Hannon's estranged daughter, claiming to have just arrived from Paris. McBain, while suspicious of her sudden arrival, eventually left the building after finding no evidence implicating Douglas.
Sometime later, a bartender who witnessed David kill Hannon tried to extort Douglas for money, before being murdered by David in Douglas' body just as he was about to give the information to the police. Linking the murder to Douglas, McBain had him arrested and jailed by a SWAT team, although he was promptly bailed out by Jane. After investigating further, and attempting to contact the supposed Paris authorities, presumably from a separate simulation, McBain found no evidence that Hannon Fuller had a daughter. When Douglas attempted to find Jane in a hotel she had been staying in, he was met by McBain, who told him the truth. Douglas, confused, tried digging deeper, finding the simulated woman whose body Jane had been using, and soon discovered the truth of his world by attempting to drive to Tucson, seeing the world dissolve into wireframe. McBain, presumably following him, also discovered the truth some time later, just in time to be called by Jane Fuller, who had reentered the simulation. McBain arrived at Jane's location, Hannon's company's office, just in time to see David, in Douglas' body, about to murder her in the lobby. McBain promptly drew his gun and shot through a window, hitting David in the chest and killing him, allowing Douglas' conscious to awake in David's body in the world above.
Despite knowing he was just a computer program, McBain kept his sanity, unlike other simulations, and only had one request for Jane: to leave him and the other inhabitants of the simulation alone. Jane agreed, and then returned to her world, and McBain presumably stayed in his profession.
