Leviathan

Dragon god of the Sea. Leviathan is a son of Bahamut and Tiamat, and most certainly takes after his mother more than his father. Leviathan appears as a gargantuan serpent of the depths, and often demands tribute in the form of whole galleons loaded with gold and trinkets. It is exceedingly unwise to refuse Leviathan’s demands, when he appears. Leviathan has several temples in the harbor towns of The Pirate Isles. His priests are often “sea-dragonborn” with large frill-like gills on their backs and necks. Leviathan is not above calling sudden waterspouts or storms upon ships that have forgotten to offer him tribute after a successful raid. Like all dragons, Leviathan hates Talos. The feeling is quite mutual.
