In a quiet corner of the Natural History Museum’s instrument gallery, you find an unassuming object, graphite grey, small enough to fit in the hand, on a small pedestal. The placard reads: “Musical Instrument? Date: Unknown. Provenance: Unknown.” The placard directs you to hold it up to your ear. When you pick it up, a small wave of nausea washes over you. You hear a faint humming sound coming from the object. You attempt to hum a matching note. Suddenly, darkness closes in around you and you fall to the floor. You awake to find yourself in a field near the edge of a forest. Standing up, you see a small group of men approaching, all armed.
