Sea serpent

Sea serpents were dragons that swam in the seas across the realms. Sea serpents, alongside dragon turtles, were some of the most feared predators of the deep, and many sailors’ would try their hardest to avoid them.

"When a sea serpent drives itself through the hull of a ship, it’s simply trying to accelerate the molting process. Sure, the ship might sink, but that’s hardly the serpent’s fault."

- Fizban

Physical Description
Sea serpents were characterized by long serpentine bodies adorned with blue scales across their main body, with red scales coating their accessory appendages. They had forked tongues. They possessed a frill across the spine, with a collection of frilled fins at the head. Sea serpents were amphibious.

Personality
Sea serpents were territorial, and aggressively so, just as the same as any other dragons, and they did not take kindly to ships traveling in their territory, especially if the ships were going over their domains without permission. Some were capable of being appeased by offerings of treasure, but most demanded that a ship’s crew should sacrifice one or more of their own. Living amid the wreckage of sunken ships or in deep-sea caves, sea serpents collected the cargo of the craft they sunk, amassing great collections of trade goods, sailors’ trinkets, and pirates’ stolen treasure.

Combat
At any age, a sea serpent would be capable of attacking with its bite, its tail, and a constricting grip. Their strong fins propelled them through the waters of the seas and oceans at impressive speed. Young sea serpents were nimble and agile hunters; they use reefs and natural camouflage to hide before they assaulted their prey, individually striking members of the crew of a ship. Ancient sea serpents grew large enough to demolish whole ships with almost absolute ease, then fed at their own leisure on helpless sailors in the water.

They had a breath weapon described as a breath of rime, a cone-like stream of cold so frigid that it could leave sailors’ corpses floating frozen amid the wreckage of their ships.

Ecology
Sea serpents could be found in the waters off the Sword Coast, predominantly referred to as the Sea of Swords.
