At the table
You can breathe air and water.
You have a swimming speed of 30 feet.
You know the Shape Water cantrip. When you cast it with this trait, you choose Intelligence, Wisdom, or Charisma as your spellcasting ability for it.
You can make your bioluminescent spots glow or go dark at will. While glowing, they shed dim light in a 5-foot radius. You can use simple, visible patterns to signal nearby creatures, though conveying complex ideas requires a shared code or language.

Nerith often cultivate Constitution and Wisdom through an amphibious life attuned to changing currents, but these are tendencies, not limits. Assign ability score increases according to your table's character-creation rules.
Their light-spots are especially vivid, often visible even in bright surface light.
Sunlit Shoal nerith inhabit shallow reefs and lagoons. Their communities are known for elaborate signal-dances and close ties with coastal settlements.
Nerith are coastal amphibians whose seawater hair streams like a current and whose glowing skin speaks in flashes. At home among reefs and tide pools, they read the sea as both landscape and living neighbor. Some venture inland as guides, envoys, or adventurers, carrying the habits of the shore into a world that rarely notices how much its fortunes depend on the water.
Nerith are amphibious humanoids with smooth, light-blue skin patterned in tiny, close-set scales reminiscent of a shark's hide.
Their fingers are webbed, their teeth slightly sharp, and their eyes are uniformly black, without visible whites or irises. Their hair is living seawater, flowing and shifting with their movement; it may bead into droplets in dry air but remains connected to the scalp. Slender gill slits lie along either side of the neck. When out of water, bony plates close over the gills to protect them. Clusters of bioluminescent spots across the skin can brighten, dim, or pulse in patterns used for communication, hunting, courtship, and recognition. Internally, nerith have efficient lungs and gills, flexible rib cages, and a circulatory system adapted to alternating between air and water. They eat fish and other seafood, and their bodies tolerate the salt and pressure of coastal habitats better than those of most land-dwelling humanoids.
Coastal waters, reefs, lagoons, estuaries, and nearby shores
Young nerith learn to swim, read currents, and use their first deliberate light-signals under close family care.
An adult is expected to take part in community duties and may travel beyond their home waters. Most reach adulthood around age 18.
Older nerith often become navigators, keepers of oral histories, or stewards of spawning grounds. They may live for roughly 120 years.
Nerith culture places importance on shared responsibility, reliable signals, and knowledge of local waters.
A light-pattern can serve as greeting, warning, invitation, or a nuanced account of events, with meanings that vary between communities. Courtship may involve displays of coordinated color and motion, while hunting groups use brief flashes to position themselves without disturbing prey. Families and neighbors commonly share care of young and protection of spawning sites. Nerith diets center on fish and seafood, gathered with an eye toward seasonal abundance.
Nerith traditions honor tides, currents, storms, and the renewal of reefs, often through reverence for sea deities or local spirits.
Practices vary widely: some communities keep shrines in tidal caverns, while others treat stewardship itself as sacred duty. Their culture has no single alignment; mutual care is prized, but personal independence and adaptation are valued as well.
Nerith readily trade with shoreline communities, especially for tools, cloth, and goods that are difficult to make underwater.
They can be wary of fishing fleets and coastal industry, but are not inherently hostile to surface folk. Their use of light-patterns can be mistaken for decoration or emotion by outsiders, when it may instead be precise speech. Nerith often judge neighbors by how they treat shared waters and the creatures living there.
Nerith communities favor sheltered reefs and coastal coves where fresh water and sea life are close at hand.
Underwater homes are shaped from living coral, stone, shell, and woven kelp, with broad passages that accommodate swimmers and eddies that carry sound. Shore settlements use raised walkways, tidal pools, and shaded freshwater basins. Their buildings are designed to survive storms and to leave spawning grounds undisturbed.
