#arch#, Imagine a colossal single arch, carved from obsidian-glass alloy, glowing with bioluminescent mineral veins in aquamarine and lavender. Its fractal curves spiral and loop into impossible helices, bending physics and reality. Suspended crystals refract soft ambient light, casting warped shadows. A levitating crystalline core pulses harmonic vibrations, deforming the arch’s smooth yet weathered surface. Intricate carvings of alien glyphs and equations run along its inner curves, while moss-like lichen grows in fractured crevices. This living monument embodies cosmic memory, infinite recursion, and sacred geometry — an alien relic frozen in time. #arch#
