Heartshadow is a sleek, medium-sized sword with a dark, almost ethereal blade that seems to absorb light, giving it a shadowy appearance. The blade is slightly curved, with intricate engravings that glow faintly in a deep purple hue, suggesting a connection to the Void. The hilt is wrapped in dark leather, providing a secure grip, and the guard is minimalistic yet ornate, featuring subtle geometric patterns that match the blade's engravings. The overall design balances elegance with a menacing aura, perfect for a weapon tied to the Void's mysterious powers.
