Art style: premium fantasy game item icon, like a legendary artifact from Genshin Impact meets
Chinese celestial mythology. Irregular mystical seal/sigil shape (NOT a circle), multi-layered
embossed relief with depth, a luminous core symbol glowing from within, orbiting particles,
ornate celestial border patterns (cloud wisps, constellation dots, dragon-scale textures).
Material: starlight-forged crystal + shadow metal + moon jade, with inner glow and outer radiance.
Background: transparent. Lighting: dramatic rim light from top-left, warm inner glow from center.
Color palette: deep cosmic indigo base with the badge's signature element color as accent.
The badge should look ALIVE — not a static icon but a captured moment of celestial power.
4K quality, octane render, ray tracing, cinematic lighting, 8K detail.

A legendary fantasy artifact icon: "The Key of Three Realms" — an awe-inspiring seal shaped
like an ornate celestial key floating at the intersection of three intersecting orbital rings.
The three rings — sapphire, emerald, and amber — represent three different knowledge domains
the learner has mastered. Where the rings intersect, a brilliant diamond-bright key (#38bdf8,
verging on pure white at its brightest point) materializes from the convergence of energies.
The key's handle is shaped like a miniature galaxy spiral, with domain-colored stars orbiting within.
Its shaft is forged from crystallized moonlight, and its teeth are constellation patterns —
each tooth a different knowledge point, together forming a "universal key" that can unlock
any door in the celestial academy.
The three rings are not static — they appear to be slowly rotating, their orbital paths
leaving faint rainbow afterimages in the space around the seal.
Orbiting: three domain-colored comets following the orbital paths of their respective rings.
Lower third: diamond-bright banner "三界通衢", subtitle "跨界之钥".
Mood: The ultimate achievement — transcending boundaries. Cosmic, infinite, legendary.
