Oceanus dragon

Oceanus dragons were amphibious planar dragons who lived in the Upper planes, in particular along the River Oceanus.

Description
Oceanus dragons resembled giant winged eels. Their limbs were relatively short and their fingers were webbed. They could breathe both water and air and could live indefinitely in either environment. They were capable of flight, but tended to prefer underwater environments.

Personality
Tireless patrols of the Oceanus, these dragons fiercely protected their territory against any sort of evil creature.

Combat
The preferred weapon of Ocanus dragons was their tranquilizing breath weapon. They preferred to quickly neutralize their adversaries with it and their innate spellcasting abilities, which included control water, control winds, detect evil, dispel evil, holy smite, holy word, and water breathing.

If facing stronger opponents, Oceanus dragons did not hesitate to bring their formidable battle skills to bear. They counted with a lightning breath weapon and, akin to paladins, could deal devastating physical damage against evil creatures.

Society
Oceanus dragons guarded the River Oceanus, protecting travelers along its course from evil creatures and natural hazards. Although they spent most of the time on patrol, it was common for Oceanus dragons to visit the Dragon Eyrie from time to time.

They could be found alone or in families as they raised their young. Clutches of young Oceanus dragons were also commonly found.
