The Castle's Oath

Book One of the Blood and Creed Saga

The storm began the night Astra Potter learned she was never meant to live in chains.

Rescued from the Dursleys by her mother's uncle-a shadowed Assassin who reveals her true legacy-Astra is thrust into a world far older and more dangerous than Hogwarts or the Ministry. The Evans line stretches back to Egypt, the Potters to the Norse, and both bloodlines are bound to the Brotherhood of Assassins, sworn to fight the Templars who weave their chains across the world.

But freedom comes at a cost.

As Astra trains under Armand and joins a hidden circle of heirs-Draco, Theo, Blaise, and Luna-she learns to bleed, fight, and kill in shadow. Together they uncover ancient chambers beneath Hogwarts, walk memory's paths to awaken their bloodline gifts, and name their first missions as Creed. New recruits are tested, shadow-names chosen, and blades sharpened against the ever-tightening grip of the Templars.

Yet Astra is torn between Stormborn, the name the Creed gives her, and Astra Potter, daughter of Lily and James. When Remus Lupin and Sirius Black resurface in her life, teaching her instinct and rebellion, Astra must choose whether blood is a chain or an anchor.

And when Dolores Umbridge rises as the Ministry's hand inside Hogwarts, her decrees binding the school in new shackles, Astra and her triad are given the Brotherhood's deadliest order yet: an assassination that will change Hogwarts forever.

In the shadows of freedom and fire, Astra must decide who she truly is-Potter, Stormborn, or something more.

No chains. No masters. Only freedom. Only Creed.
