The Flying Courier is a small, winged creature with a semi-realistic fantasy design, resembling a cross between a bird and a mythical beast. It features a streamlined body with smooth, feathery textures and subtle metallic accents on its harness and carrying pouch. The wings are broad and slightly translucent, with a delicate membrane structure, while its eyes glow softly, indicating its magical nature. The courier's color palette is vibrant yet balanced, with primary colors that stand out against the game's environment, ensuring visibility during gameplay.
