Five thousand years ago, when mortals were a mere thought in the mind of their creator, Lucifer was cast out of the immortal realm of Valleyner, doomed to spend his days in the Dark Beyond. After Hanell the Creator, known as the Pale Lion, fashioned the mortal world of Thelsten, a secret concealed from mortals brought on grave consequences.

In the remote village of Heedeon, Bellwound Throvar and Arnon Helvug are visited by immortals from both shadow and light. A weapon known as the Mezar is found, believed to house the Luciferian Epistle written before he, the Dove, suffered judgement by the Regents—gods of ultimate power and parents to Hanell the Creator.

The two boys set out on a journey with a member of the Nephilim, hoping to find answers to their mysterious past. But secrets and lies do not ask for the right time to strike. A dark tale spreads: whispers that the Dove was expelled by the Pale Lion not because of rebellion, but because of their love for one another. While struggling to confess his true feelings for Arnon, Bellwound realizes that love won't be enough to save them from their own doom—not when it's caused by love itself.

As they travel across forests, deserts, and seas, they discover that the ploy of the gods will not only change their own world but will also claim lives, crowns, and kingdoms...
