For nearly five centuries, no child has drawn a first breath. The Creator sealed the womb of the world, and humanity learned to live without its future. But in the depths of Triune, another kind of genesis rose. From the Middle comes a child with power and lineage to rival the Creator. Not born, but woven. Not raised, but awakened. Bodies shaped by design. Souls coaxed from silence. Each one a crafted echo of what humanity once was. Those who survive their emergence ascend to the Upper. Those who falter are reclaimed by the dark. On the night meant to mark their passage into adulthood, five friends stumble upon a truth older than scripture and sharper than prophecy: The first humans were not what they were told. The gods were not who they claimed to be. And the Children of Triune were never meant to ask why. Some truths don't set you free, they come for you.
