Some oaths were sworn on a mountain. Others were sworn on Mars.
When a 2,600-year-old Celtic knight with a sentient sword hears the Cydonian Oaths replay for the first time in five millennia, the war he's been fighting for centuries suddenly has a new front.
Cian mac Morna has hunted the scattered remnants of the fallen Watchers for twenty-six centuries. But when the Mars steles awaken and broadcast the original oaths of the rebel angels, he realizes the flood was only an intermission.
Now an ancient network is racing to decode the steles; a woman who survived the Flood by becoming something far more dangerous is moving pieces into place, and the acoustic architecture of reality itself is beginning to crack.
Deep in the Cydonian plains of Mars, orbital imagery has revealed something that should not exist: a sigil carved before the Flood. The mark of an oath sworn by two hundred fallen angels before they destroyed the ancient world and were imprisoned in chains of darkness. An oath that was never meant to be found.
But Naamah found it first.
She has many names across many centuries. The Watchers called her their queen. Scripture calls her the Whore of Babylon. And she has spent five millennia building the infrastructure for their release-corrupting bloodlines, cultivating power, and waiting with inhuman patience for the one thing she still needs: the key to the Abyss.
Now a private Mars mission is racing toward Cydonia. The sword Cian carries is made from the same ancient ore as the chamber on that red plain. And somewhere in Eden, the prophets Enoch and Elijah have been waiting-sustained by the Tree of Life-for the hour of their return.
The chains are weakening. The oaths are stirring. And Cian mac Morna-2,631 years old, deeply scarred, and constitutionally incapable of following orders he disagrees with-must prepare for a war that scripture promised was coming but no one believed would arrive in their lifetime.
It has arrived.
THE CYDONIAN OATHS is the first volume in The Nephilim Chronicles-a five-book biblical apocalyptic thriller drawing on 1 Enoch, the Book of Jubilees, and the prophecies of Revelation. This is not just another supernatural thriller.
This is where tactical military precision meets biblical apocalyptic fiction - where the principalities and powers of Scripture are treated as real operational entities.
For fans of Frank Peretti, Tom Clancy, and Ted Dekker-an epic series that blends high-stakes action with profound theological depth.
The outcome of the war was decided at Calvary.
The final battle begins now.
