Light Priest, Necromancer's Soul

When Ivan awakens in a fantasy realm with a crystal skull fused to his very being, fate plays a cruel joke—he becomes a priest of the Church of Light. Now he must navigate a world of warring professions, exotic races, and a magic system on the brink of collapse, all while hiding the dark power that thrums beneath his holy robes. But when a second crossing shatters reality itself, Ivan's dual nature may be the only thing standing between salvation and oblivion.
