Using the image as a reference, design a clearly fictional alien space weapon for Our'World. Far from the original but similar in design. Extend the barrel casing by ~10 percent, soft rubberized grip. Inset glowing cyan energy glyph line running its length. Add an Aevyr Blue glow line near the muzzle, and an etched faction glyph above the grip. Engrave a model number along the barrel. Make it bulky, futuristic, ultra-realistic, with a stylized backdrop for sale.
