The Demon's Light is a powerful source of pure, red, glowing energy owned by the Demon. It has kidnapped Messenger, driven Baroness mad, and not yet touched Korra or Chase McFly. It possibly did something to Scarlet when he was young. It may like the team, as it saved Messenger Deception. It dragged Michael into the woods. It is actually the Demon's lost soul that was stolen by Kaz Heater.
