The Laetum is a sleek, futuristic sidearm with a flowing, organic design that mimics biological forms, featuring smooth, curved surfaces and a glossy, metallic finish. Its barrel is elongated and slightly tapered, with intricate, glowing blue energy channels running along its length, suggesting a high-tech energy weapon. The grip is ergonomically shaped, with a textured pattern for better handling, and the overall color scheme is a combination of dark metallic tones with vibrant blue accents that pulse faintly when activated.
