Vesper, the Amazon of the Knights of Nyx, is a formidable warrior versed in the practice of Etheric magic. She uses her talents in the service of Prince Crimson Nyx, with whom she shares the dream of a kingdom where people of all races can live together. But in the midst of celebrating an important victory for their kingdom, the two heroes are ambushed by the Ekklesia, a religious order that sees in them the manifestation of dark forces that must be stamped out... A fast-paced first entry of a thrilling fantasy series not to be missed.

Accompanied by Zarak, a mischievous familiar who doubles as a deadly weapon in battle, Vesper sets a course for Valestiel, where Prince Crimson Nyx is thought to be imprisoned. She knows she cannot free him by herself, however, so she decides to call upon the help of her former companions, the Knights of Nyx. But she will have some convincing to do, given the steep losses the Knights have already incurred. Beyond that, a crucial question remains: is Crimson even still alive? And if so, in what state? More than their own lives will be at stake when Vesper discovers the truth, as she is moved in her desperation to an act of folly...

To save Crimson Nyx, Vesper makes a pact with the Archimerist, creator and master of Novicus. Only, when the latter discovers the prince's noble origins, he betrays Vesper by fleeing with Crimson's soul. Vesper then discovers the existence of her half-sister, Vanea, whose aura has mysteriously disappeared. Accompanied by her faithful chimera Zarak and a surprising crystal child, Vesper races against time to find Vanea and discover the Archemist's true intentions. This manhunt leads the group to the dark ancestral temple of the Aurora Crux, where a cursed and bloodthirsty warrior awaits them.
