Sea Dragon (Young, Spellcaster)

CREATURE 8

Imperial sea dragons are associated with elemental water and oversee rain, storms, rivers, and oceans. They live adjacent to the civilizations of Tian Xia, ready to aid mortal affairs and prove their worth. For some sea dragons, providing assistance in matters of the weather and arcane knowledge is a duty. For others, it's a perk that leads to valuable tributes or delicious meals. Visiting petitioners are all too eager to provide, for it's said that when a sea dragon is pleased, the rain is gentle and plentiful. In contrast, when they're angered, the storm spares none from its fury.

Despite common Tian belief, civilization hardly lives at the mercy of the sea dragons, for most are subjects of kingdoms sworn to assist mortals. Most sea dragons are subjects of one of the four sea dragon kings, whose nation or united territories are based out in the Embaral Ocean, Ivory Sea, Okaiyo Ocean, and Songil Sea. Given the lack of native sea dragons on the Plane of Water, it's theorized that these kingdoms might be remnants of a mass exodus from the Boundless Sea. The sea dragon's own myths say their kings of old took oaths to escape persecution from the Elemental Lord Kelizandri. While it's uncertain if the Brackish Emperor yet seeks to exterminate the sea dragons, most uphold the sworn promise as part of their cultural heritage or in honor of their forebears.
