You've stumbled upon an abandoned castle, one that hasn't been used to many years. Taken over by the surrounding plants. Exploring this place takes you to an old room, which can only be assumed to belong to a long dead king by the looks of it. You stumble upon a seemingly normal mirror, but touching it causes to glass to magically disappear, and a being that looks exactly like you steps out.
