Hyper-realistic Image

A 3D hyper-realistic image of a glass skull with neon purple light emanating from within, casting intricate reflections and refractions through the transparent structure. The skull is suspended in a void, set against a pitch-black backdrop, and the scene is rendered using the cutting-edge capabilities of the Octane engine. The light pulses subtly, enhancing the atmosphere with a mysterious, futuristic aura, and the skull's surface shows delicate etchings, suggesting alien origins and adding to the sci-fi mystique.
