Sea Dragons are also a species of Dragons that have allied themselves with the Norvagen. They have a fish-scale appearance and long necks with bones sticking out.
Known Sea Dragons include:
Beithir, Draknar, Lindwyrm, Midgaard, Tarnloch, Rawlsong Ocean Camouflage Dragon
Oddly, Tarnloch from the Wizard's Sea Assault set is refered to as a sea dragon despite the fact that he actually is a two-headed Draigar dragon. Rawlsong is known as the lord of the entire ocean and therefore the dragons who inhabit it.
