The Avelyn is a crossbow-like weapon with a distinctive triple-barrel design, allowing it to fire three bolts simultaneously. Its body is crafted from dark, aged metal with intricate engravings depicting ancient warfare, giving it a menacing and ornate appearance. The weapon features a sturdy wooden stock for stability, with a polished finish that contrasts with the rough, battle-worn metal components. The triple barrels are aligned horizontally, each with a slight taper towards the front, and the mechanism includes visible gears and cranks, emphasizing its mechanical complexity. The overall aesthetic is dark and foreboding, with a color palette dominated by blacks, deep browns, and muted metallic tones, reflecting its origins in a grim and perilous world.
