Digital render of a crystal sword, composed entirely of intricate glowing neon wireframes, shaped with sharp, angular facets. The sword's center is a hollow void, with a faint glow emanating from within. The sword is floating mid-air, surrounded by faint holographic particles. The neon colors contrast against a dark, cosmic background. Soft, ambient light casts subtle highlights on the glowing edges. The atmosphere is futuristic, with a sense of mystery.
