Hundreds of years before a comet hit Earth and created a cold dark world ruled by vampires...

A wandering Roman centurion saved a woman from being sacrificed by druids. Honor bound to return Fionnuir to her homeland Rook embarked on a journey across ancient Britain where all manner of human and inhuman creatures dwelled...but none more dangerous than the demon he'd sworn himself to.
