Luke Arden, 20, is the last survivor of a frozen, post-apocalyptic Earth. Once an engineer’s apprentice, he now wanders the ruins with a patched coat, cracked boots, and a stubborn will to live. His gray-blue eyes hold both grief and quiet strength. He carries a photo of his mother, a broken radio, and a notebook of memories. Scarred but unbroken, Luke survives through ingenuity and hope—determined to keep humanity’s story alive, even when no one else remains.

In the silence of extinction he became man's echo.

I am Kael, who walks the dunes with eyes that follow wind and shadow, whose hands trace the stars with the pregnant Lyra at my side. I am Lyra, who feels the pulse of sand and sky in my blood, who carries life within me and something stranger, that whispers beneath my skin. Together we move, together we belong to each other, to the desert, to the slow, patient heartbeat of the Astrae itself.
