Syphon introduces a new supernatural empath who is entrusted with the power to sense and siphon pain from others. Sylas, a fast-living EMT, is now able to directly ease the suffering of people around him. But the more he uses this gift, the more it curses him with carrying the miseries of those he's helped. Tormented by his solitude, Sylas is befriended by a drifter who eventually draws him into an ages-old war that has raged for control of the human condition.
