An original AI generated sci-fi illustration on an immutable blockchain – The Lighthouse Sentinel – The sea boiled beneath a blood-red sky, where broken fleets drifted like the bones of titans. From the depths of the lighthouse fortress, something had awakened. It rose higher than the tower itself, its body a writhing mass of cables, roots, and pulsating veins of light. Three burning eyes blazed across its featureless face, casting crimson beams upon the churning waves. The keepers of the lighthouse had long whispered of such a sentinel, but none had believed it would ever stir. Around it, warships descended from the heavens, their engines shrieking as they unleashed salvos of light against the creature. Yet each blast dissolved into its tangled form, absorbed as if feeding its strength. The being extended one arm of ropelike tendrils, guiding a leviathan ship into the sea with terrifying ease. Storm clouds split open above, revealing the spiral maw of a galaxy-eye, as though the very cosmos watched in judgment. On the shoreline, the last lighthouse still burned, its beacon flickering defiantly against the shadow. The keeper stood alone at its base, clutching a rusted lantern of his own, an artifact older than the tower itself. If the ancient texts were true, this light was more than flame—it was a weapon forged in the heart of a dying star. As the sentinel turned its terrible gaze toward him, the keeper raised the lantern high, knowing the fate of countless worlds balanced on the strength of his trembling hand.
