Ecology

Young Sea Serpent is one of the elder species, claiming a wide territory and shaping the ecology around it for centuries. It is most often found in underwater regions. It is huge-sized, which shapes how it hunts, hides, or fights.

Behaviour

Young Sea Serpent is intelligent, vain, long-memoried; it remembers slights for centuries and rewards loyalty in kind. Its Neutral alignment shapes how it engages with the world — predictable in tendency, even when unpredictable in detail. It is intelligent enough to plan, scheme, or remember.

Origin

Young Sea Serpent is expanded in Fizban's Treasury of Dragons. Dragons in D&D canon trace to Bahamut and Tiamat, with each lineage having its own founding myth. Within a campaign, its existence anchors a region with the kind of weight only an old, named species carries.
