In the rotting port town of Harrow's Point, Kael Varanis - a hunter of horrors born from the Void - sets out for the Sunken Library of Calthyr, where ancient knowledge may hold the key to a sickening world. But the road south brings a detour he cannot ignore: a grey beast prowling the marshlands of Val-Normarie, leaving behind slaughtered flocks, missing children - and the possibility of a new Void Stalker.
Soon everything goes sideways, as Kael is being forced to find and destroy a strange beast that leaves its victims untouched, while he tries to find a mysterious woman that flees in his apearance. Hunter and Prey, Beast and Victim are nothing but roles that keep changing in an endless pantomime.
What can be the truth in a place where Mercy is forced to create beasts?
