Keep moving

Worried about what might happen if the demon returned, you decide to keep moving, heading for the door at the other side of the room. It is cold and metallic to the touch, and when prompted, the handle turns cleanly and the door slowly swings open, with the loud sound of metal scraping against stone.

Entering into the room, it appears to be some sort of medical facility, with medical tables strewn about among operating equipment, bags of fluid, and other unidentifiable machines. Outside of the sounds from your entrance, the halls are completely silent, and the sound of your footsteps echo through the room. It's large and circular, almost as if it's an entrance hall. There are three hallways leading off of the room, each at a 90º angle from the door you've entered through. Each hallway has a word written above it, likely describing it's location. Directly ahead leads to the Supervisor's Office, the left hallway goes to operating rooms, and the right hall is labeled simply "Experimentation."

A large desk is directly in front of you, rectangular and unattended. One machine in particular sticks out- it's bigger than your body, made mostly of metal, and tucked away in a corner nearby, between the door you exited and the operating rooms. Opposite of the machine, there's a small patch of green where foliage has broken into the facility, complete with a small pool of water.
