For decades the Watcher had scanned the depths of space for the Invaders. Their conquest of devastated Earth meant the end of the Guild, so he travelled to the ancient holy city of Jorslem where he hoped to regain his youth and claim the Flier he had come to love.
But the slim young girl who soared on luminescent wings held the keys to Earth's freedom and for the Watcher a new purpose.
