Coldfire

Coldfire is a dark science fiction and fantasy series set on Erna, a seismically active world colonized by humans but plagued by the fae, a natural force that manifests people's dreams and nightmares. Twelve centuries after settling, humankind maintains an uneasy stalemate, with some manipulating the fae for profit, unknowingly empowering demonic forces.

The series begins as dark fae multiply and four individuals – a Priest, Adept, Apprentice, and Sorcerer – are drawn together to face an unimaginable evil. Their mission will jeopardize not only their lives but also humanity's fate. As the series progresses, enemies must unite against an evil greater than anything known. A warrior priest and an undead sorcerer must confront a powerful demon named Calesta threatening to enslave mankind and remake humanity to sate an unquenchable thirst for suffering. Their battle will take them to the depths of Hell, risking everything to save humanity's soul.
