The Black River is a sinister, curved greatsword with a blade that appears to be forged from darkened steel, giving it a menacing, shadowy appearance. The blade features intricate engravings of flowing river patterns that seem to shimmer with a faint, eerie glow under certain lighting conditions. The hilt is wrapped in aged, black leather, providing a secure grip, and is adorned with a skull-shaped pommel that adds to its ominous aesthetic.
