In a parallel universe of indescribable beauty, the kingdom of Eterno is governed by the most powerful deities, whose power derives from human faith. However, with technological progress on Earth, humanity has ceased to believe, weakening the deities and strengthening an ancient threat: Abaddon, the Destroyer Angel.
Alessandro Corvin, a brilliant Italian scientist, develops the Etheric Energy Generator (EEG), a device that accidentally opens a portal between Earth and Eterno. Transported to the divine realm, Alessandro discovers that his invention could be the decisive weapon to combat Abaddon.
Guided by the Pantheon of Gods, Alessandro must learn to control the EEG and collaborate with the deities to rekindle humanity's faith. Meanwhile, on Earth, spiritual disconnection fuels the negative emotions on which Abaddon thrives.
In a race against time, Alessandro and the deities unite to confront Abaddon in an epic battle that will determine the fate of Eterno and Earth. Through courage, faith, and collaboration, they seek to restore universal balance and save both worlds from imminent destruction.
In the epic conclusion to the Devil's Deal series, Freya has one final chance to discover the full potential of her own power, and to use it to restore balance in the universe - once and for all. After the destruction caused by Roisin, Ferya and Torix come to terms with their losses and mistakes... And prepare for a final battle that will change everything.
