The god of sleep and dreams is content to give you nightmares. All so he can go home (the other gods kind of left him behind on Earth). He teams up with a vindictive bitch (who is not Lilith) in order to spread Shadows across the Earth. The Shadows taint Others and kill humans. They’re just a bunch of fun, really. Morpheus appears and subsequently disappears in the book In the Time of Toba, but he’ll be back… As soon as you close your eyes.
Even the god of sleep has to be held accountable. Count the sheep if you dare.
