Sea Dragon is a set released in the Krystal Wars series. It contained a few Norvagen, Draigar, and Vorgan warriors.

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.
