The Tenet Weapon is a high-tech firearm with a sleek, futuristic design, featuring a combination of metallic and energy-based components. Its body is primarily constructed from a dark, polished metal with glowing energy accents that pulse with a vibrant, color-shifting hue, indicating its powerful and unstable nature. The weapon's form is angular and asymmetrical, with a prominent energy core visible through transparent panels, and intricate engravings that suggest its origin from advanced Orokin technology.
