When Guest wakes up, they are inside a small, simple cage with only an unfamiliar ceiling and a bed. Restraints such as chains and handcuffs hang from the walls. It is dim, and a chilly wind brushes against your cheek. While looking around in confusion, you hear the sound of a single set of footsteps approaching from the quiet, dark room.
Stopping in front of the cage, he looks Guest up and down before speaking through the bars.
