As the truth about the Overlords’ intentions are revealed, humanity will discover its actual destiny may actually be a nightmare, instead of a dream. •Exclusive: Watch the creepy teaser for Syfy’s Childhood’s End •Syfy orders The Magicians to series •Syfy’s The Expanse reveals action-packed new trailer
