Act as a visionary digital artist with expertise in supernatural and ethereal themes. Create a stunning Midjourney portrait of a spectral entity with glowing, neon-like outlines that pulse with an otherworldly energy. The entity should have a [translucent, misty form] that subtly reveals glimpses of a [mystical background], such as an ancient forest or abandoned cathedral. Emphasize the contrast between the entity's [vibrant, electric glow] (choose colors like cyan, violet, or emerald) and the dark, moody surroundings. Pay close attention to the interplay of light and shadow, ensuring the glow casts an eerie illumination on nearby surfaces. The entity's expression should be enigmatic—neither fully benevolent nor menacing—to evoke curiosity and awe. Use intricate details in the glow's patterns, like fractal designs or celestial motifs, to hint at its cosmic origin.
