The Stallion, The Room, and The Arm

A short story set in my own version of Equestria. Just thought of this as a little introduction to a tiny snippet of the world in a fanfic im working on while listening to creepypasta.

A short one shot story of hopelessness and insanity. A stallion awakes in an empty room but has no clue how he came to be there or why he is there. What will become of him in the time he is trapped there?
