Dark Mirror

"The Dark Mirror shows near future. If your reflection is clear, then perhaps good luck is coming. If it is opaque, then braze yourself for some bad luck in your way..."

- Daniel Blake to Steve

The Dark Mirror is a magical item that can replace an object, person, or animal from the real timeline of worlds, to their mirror counterparts from the Mirror Timeline and vice versa. It is known as one the very few ways to transport between timelines.
