From publisher blurb:
Heed the Signs and Beware
The seals of the Abyss are sundered and demons walk the earth again, claiming souls as they vie for dominance across the globe. Hidden within their ancient sanctums, the Earthbound stir after millennia of sleep, summoning their scattered worshippers and forging chains of slavery for fallen and mortal alike. Now come the words of Lucifer himself, lost Prince of the Fallen, warning of the terrible cataclysm to come.
The Days of Fire Are at Hand
Demon: Days of Fire presents a vision of the world on the brink of apocalypse, as ancient powers clash and the future of mankind hangs in the balance. Will the fallen destroy the threat of the Earthbound forever, or will the mad gods of legend bring about eternal night? Will the world be destroyed or reborn in the dawn of a new age?
