The Grey often attack people, young and old, by driving them mad through their dreams. The mysterious man known only as the Dream Catcher has discovered a way to combat this insidious threat. Just like the Grey, he hunts at night, leaping across roof tops and clambering fire escapes. As he stands guard over the sleeping, he can exorcise nightmares, conjure them into real, physical monstrosities, and then he battles them. His fights are brutal, and he finds himself frequently in great peril, but he will not rest, and he will not quit.
In the world of New Gaius, creatures from the Grey have invaded, and humans are a dwindling species. Beings of magic and myth have manifested to protect and integrate with the last survivors. But still, the fate of humanity is uncertain in this strange, beautiful new world.
