Set 100,000 years before the events of the original series, three incredible children were born to Duke Aurelius Garcia, a noble who served in King Arthur's Camelot. These three siblings were triplets, but their lives couldn't have been more different.

Azrael Orkney Garcia, the youngest triplet, and his sister Eon have always been outsiders in their own home. While their eldest brother Raphael got all their father's love and attention, Azrael and Eon were pushed aside. All they wanted was simple: either get their father and all relatives to love them like they loved Raphael or find a way to leave their father's control behind.

But life had bigger plans for these two inseparable siblings. Strange events begin to unfold, pulling Azrael and Eon into dangers they never asked for. This story shows how two siblings went from wanting freedom and peace to challenging the very gods who ruled their universe, setting up events that would echo through thousands of years to come.

Rael's grip tightened around his scythe. "This is it, Eon."

Eon nodded firmly. "Let's finish this."
