A highly minimalistic and modern vector favicon icon for a dark hacker forum. Perfectly centered, scalable, square composition with no textures. Background is deep matte black (Hex #000000). The central emblem is an interwoven, geometric combination of the letters 'N' and 'X', based directly on the node-network structure of image_2.png, forming a powerful nexus symbol with sharp circular terminal nodes. The entire emblem is rendered in a vibrant, glowing gradient of electric neon cyan (Hex #00FFFF) to intense neon green (Hex #39FF14). The vector lines must be sharp, precise, and clean with a high-tech, networked atmosphere, conveying a digital grid structure. The contrast between the matte black void and the brilliant, saturated neon is extreme. The design is abstract and highly symmetric, with a sharp, precise neon glow effect. Optimized for a small square icon.

The image shows a black and white logo with the letter 'X' in the middle, set against a white background.
