An original AI generated sci-fi illustration on an immutable blockchain – The Choir Below the Carbon Sky – They were the Choir Below the Carbon Sky—hollow, skeletal forms draped in sinew and wire, singing the hymn of the dying atmosphere. Their song rippled through the stagnant air, vibrating the fractured towers that surrounded them like organs of a decaying cathedral. Lightning pulsed within the storm above, illuminating the blackened clouds as if the heavens themselves trembled at the sound of their lament. Each note was a frequency older than language, resonating with the bones of the planet itself. The choir did not sing for salvation, nor for the living—they sang for remembrance. The world had long since turned to ash and circuitry, but their song preserved echoes of oceans, wind, and light. It was said that if you stood close enough, you could hear whispers of the past woven into the harmony—names of stars that had burned out eons ago. When the final tone rose, the storm broke open like a wound in the sky. A blinding shaft of cyan light descended, striking the center of the desolate plain. The Choir’s bodies began to unravel into threads of luminescent dust, rising upward toward the breach in the heavens. As the light faded, silence reclaimed the world—save for a faint hum beneath the ground, where their song still lingered, eternally resonating through the bones of the Earth.
