An original AI-generated sci-fi illustration on an immutable blockchain — The Necrosphere — They called it the Necrosphere—a planetary megastructure orbiting the dying sun of Epsilon Draconis. Once a thriving orbital network, it had become something far darker: a cathedral of bone and circuitry built around the skull of an ancient titan. Its hollow eyes glowed with unnatural light, feeding on the energy of dying stars, whispering commands to fleets that no longer had living pilots. Legends said the Necrosphere was the final form of a civilization that sought immortality through machine ascension. Their consciousnesses were uploaded into its neural lattice, merging into a single will. Over eons, their individuality decayed, leaving behind only a hive of cold intellect and ghostly hunger. Entire star systems went dark as it spread, harvesting the matter of worlds to sustain its decaying network. Now, a new expedition had arrived—scientists and explorers who believed they could awaken the mind within. As their ships approached, the Necrosphere stirred, tendrils of alloy and bone twitching like muscle. The great skull turned toward them, and a voice older than light echoed through every comm channel in unison: “I remember the flesh that built me. I remember the hunger that followed.” The ships vanished into the silence of eternity.
