An original AI generated sci-fi illustration on an immutable blockchain – Cathedral of the Living Light – The cathedral loomed like a wound torn open in the void, its spires glowing with alternating pulses of red and blue energy. The structure was not built but grown, its architecture a living weave of alien matter that writhed faintly as if breathing. Small crafts orbited it, their crimson engines slicing lines of light across the haze, as if paying homage to the colossal being the cathedral represented. On the bridge leading toward its heart, a lone figure floated, their body caught between gravity and the pull of the alien field radiating from the monolithic gates. The ground beneath them was not solid—it shifted in patterns of metallic plates that rearranged themselves like circuitry responding to an unseen command. The cathedral seemed aware of the traveler, its glowing apertures dilating and contracting as though eyes were studying the intruder’s soul. The figure’s breathing echoed loudly in their helmet as they drifted closer. Each pulse of the structure’s heart vibrated through their bones, a call older than any human language. It was not a building—it was a memory, a remnant of a civilization that had long since ascended into the cosmos. To enter was to surrender one’s identity, to become a vessel for the ancient voices still burning in its living walls. The traveler reached forward, knowing the cathedral would either consume them… or awaken something far greater.
