巨大なドラゴンの骸骨に築かれた宇宙の灯台

A colossal cosmic lighthouse seamlessly fused into the remains of an ancient star‑dragon’s skeleton. The structure rises from a massive ribcage drifting through an asteroid field, with vertebrae forming spiraling bridges, elevated platforms, and towering arches shaped like celestial sanctuaries. Bone‑white ribs curve upward like cathedral spires, intertwined with black iron rings engraved with primordial draconic sigils. Luminous celestial lenses are embedded directly into the fossilized bones, channeling residual cosmic breath from the dragon’s ancient heart‑core. The lighthouse’s central beam emerges from the dragon’s former heart chamber, now transformed into a radiant astral engine. The light pulses with rhythmic energy, echoing the creature’s long‑silenced heartbeat. It travels through the nebulae like a living serpent of stardust, awakening migrating planets and illuminating runes on distant moons. As the beam expands, it reveals the spectral silhouette of the star‑dragon’s spirit coiled around constellations, watching over travelers across the galaxy. A tall female guardian with golden‑brown skin floats beside the lantern chamber, shaping constellations with glowing astral chains drawn from the dragon’s lingering essence. She maintains the ancient alignment corridor once carved by the dragon’s flight, guiding colossal ark‑ships escaping a fading galaxy. Her presence completes the relic, acting as the final living conduit between the dragon’s cosmic legacy and the civilizations that still navigate its path. Mythic cosmic grandeur, draconic relic architecture, deep ultramarine void, bone‑white arches, cosmic gold highlights, stardust atmosphere, visionary epic composition, extremely high detail.
