A legendary magical artifact resting on a clean white background — the Heart of Aetherion, an ancient floating crystal core encased in intricate silver filigree. The core pulses with swirling blue and violet energy, illuminating faint runes that shift across its surface. Delicate mechanical rings orbit the crystal, engraved with celestial symbols, turning slowly in midair. Fine wisps of ethereal light spiral around the artifact, giving off a soft inner glow. The metal frame is adorned with sapphire-like gems and arcane etchings. The entire piece levitates slightly above the surface, casting a faint shadow on the pure white background. Ultra-detailed fantasy design, high contrast, magical tech-fantasy fusion, isolated object, studio lighting., #ocean#
