Blue dragon
Blue dragons, the spawn of Sera Dagon, the Blue Shard of Ardothun, are a type of chromatic dragons that favors aquatic habitats. Aside from their smooth, blue scales, they are distinguished from other dragons by their sleek, aquatic-favoring physique.
The Blue Dragonflight
The Blue Dragonflight, in its entirety, aside from a few outcasts and renegades, forms a tier of the hierarchy of the Aquantis Dominion, and occupies the upper house of the Blue Council, the government of the Dominion. Its leader and corresponding Shard, Sera Dagon, pledged her own and her entire dragonflight's loyalty to Randegosa the Leviathan, the Primordial deity of the sea.
