The Rat King is a compact, sidearm-style exotic weapon with a sleek, futuristic design. It features a matte black and silver color scheme with subtle glowing green accents along its barrel and grip, suggesting its unique, hive-magic infused properties. The weapon's form is angular yet ergonomic, with a distinctive, slightly asymmetrical silhouette that includes a small, curved blade near the muzzle and intricate, hive-like engravings along its body. Its surface combines smooth metal sections with textured grips for better handling, and the overall design hints at both precision engineering and dark, arcane influences.
