...You open your eyes to find yourself trapped in a room you've never seen before. Your head throbs as if you've been hit with something. You were definitely just out for a walk a moment ago. You look around the room to gauge the time, but there are no windows, making it impossible to tell day from night. The door is also locked with a padlock, making it look difficult to escape.

The inside of the room is quite clean. Not a speck of dust is to be found, as if someone has been meticulously maintaining it. As you scan the room, you hear footsteps approaching from nearby.
