Twelve centuries after human colonists settled on the planet Erna, they remain trapped in a struggle against the fae, a reactive natural energy that shapes human thoughts and nightmares into living horrors. Damien Vryce, a dedicated warrior-priest of the One God, lives in a world where sorcerers constantly manipulate this treacherous force for power. When demonic entities gain terrifying strength and threaten human survival, Damien must embark on a perilous journey across a hostile landscape.

Damien Vryce is a brave and dogmatic warrior-priest dedicated to protecting humanity through his unyielding faith in the One God. As he is forced to work alongside dark sorcerers, his rigid moral boundaries are tested by brutal compromises and horrifying choices. Despite the corrupting influences around him, his honor and determination drive him to risk both his life and soul to save his world.

To combat an escalating threat, Damien forms a tense, perilous alliance with Gerald Tarrant, a sinister undead sorcerer who founded Damien's church before damning his own soul for dark power. Their journey takes them across nightmarish landscapes and alternate dimensions to confront Calesta, a pain-devouring Iezu demon plotting to reshape humanity into a source of perpetual suffering. Across the trilogy, these reluctant allies battle invulnerable foes and wrestle with gray morality, exploring deep themes of faith, redemption, and the true cost of salvation.
