Surely the rumours couldn't be true?, You thought to yourself as you walked down the corridor holding a letter you had received from a so-called "administrator".

As you follow the notes' instructions, stepping into a broom closet and pushing the toolbox that was lying on the shelf against the wall, suddenly the floor opens up and sends you sliding down some kind of tunnel

You find yourself in Site-19's hidden basement, getting up and glancing around until you come face to face with a person basked in shadow.

"You actually came, good."

A light, feminine voice comes from the person, whom you now know as the "Administrator", who invited you here.
