The shadows were never meant to be noticed. Predators upon the human psyche, waves of a primordial Tide, they've lingered obscure beyond the opaque curtain of perception, specters with unknowable purpose, presences terrible to experience, yet easily dismissible in the light of day. In the town of Timberdam, the curtain is beginning to tear. For Cain Greyon, it tore long ago. His nightmares were once perceived as sleep paralysis. He knew they heralded something more to come, something born through him rather than from him, which he came to call the Walker-Dark. Now, from the mist wanders Roam, the Wanderer, an ancient shadow given human form by means even he does not understand. His instincts and impulses feel new, yet borrowed, and he is driven to explore them amid Timberdam's citizens as Elliot Fog. In those he meets, he finds some whom he might find easy prey, while in others, reason to worry. And in one, his ultimate reason for being ... a love which could be easily dismissed, yet terrible to experience.
