Description
Often found in the top layers of the Lower Planes, these beasts are one of the more dangerous denizens of the infinite river. Styx dragons look slightly different from more commonly known dragons. They have a long, serpentine body with small wings and claws protruding from their elongated necks. They have no legs, instead replaced by a wickedly barbed tail. Their slime-coated scales often range between dark browns and reds. Immune to the effect of the waters in the River Styx, the Styx dragons swim freely across the infinite river's expanse, easily hopping between many of the Lower Planes. They hunt and feed primarily off of fiends but more out of abundance than preference. Any creature with consumable flesh can be marked as prey when catching the attention of a Styx dragon. They normally lair deep burrowed tunnels along the banks of the River Styx.
