Create a Roblox-style 3D model of a final evolved spirit named "Radiant King" (광휘왕). Design a majestic dragon spirit infused with pure golden and white light. The body should be sleek and crystalline, with strong glowing golden scales and radiant wings. Wings must look like pure energy wings, made of shining white and gold particles, not solid structures. Add a large luminous golden halo above its head and constant soft sparkles surrounding its body. Focus on brilliant white, radiant gold, and slight soft rainbow sheens, but no blue tones. The model must look sacred, powerful, and optimized for Roblox. Emphasize a divine, awe-inspiring appearance.
