Mireborn are patient frog kin whose songs carry across fogbound wetlands and whose memories flow like rivers through generations. They can wait motionless for hours, then cross a battlefield in a single astonishing bound. To a mireborn, every pool has a history, every storm has a lesson, and every traveler may become part of the clutch.

Mireborn are compact amphibious humanoids with broad mouths, expressive gold or copper eyes, powerful legs, and smooth or lightly pebbled skin. Their coloration ranges from pond green and river brown to blue-gray, saffron, rust, and deep violet, often with mottled patterns that break up their silhouettes among reeds and stones. Their hands are nimble, with slightly webbed fingers, while their feet are broad and springy. A mireborn's throat pouch swells when they sing, shout, or speak in the resonant calls used across marsh water. Their bodies are cool to the touch and remain healthiest when regularly exposed to clean water.

Mireborn society is organized around clutches rather than isolated households. A clutch may include relatives, adoptive parents, elders, artisans, and unrelated friends who share responsibility for raising young and maintaining the spawning pool. Their culture prizes observation, memory, humor, and practical service. Important decisions are often discussed during long evening gatherings accompanied by water drums and call-and-response songs. Mireborn have a strong tradition of hospitality, but guests are expected to contribute something useful, whether a story, a skill, a repair, or a promise. Individual achievement is celebrated most when it returns value to the clutch.

Mireborn religion centers on the Turning Waters, a cycle of rain, river, flood, drought, decay, and renewal. Some revere ancestral pools, seasonal spirits, moonlit marshes, or immense unseen beings believed to sleep beneath the wetlands. Their priests preserve songs that are said to contain the names of the first rains. Mireborn communities often favor benevolent or communal ideals, but individual mireborn may be fiercely independent, secretive, or mischievous. Their reverence for balance makes both compassionate neutrality and principled good common among them.

Mireborn homelands are organized around spawning pools, waterways, and shared gardens. Their homes are low, rounded structures of clay, reed, bark, and woven roots, often built on platforms above the water or nestled inside living banks. Important settlements include broad communal halls where sound carries across the water, rain courts designed to collect and filter storms, and memory gardens planted with species associated with the dead. Roads matter less than canals, rope bridges, stepping stones, and marked channels navigated by lanterns.

Mireborn are generally welcoming toward travelers who respect water, living creatures, and local boundaries. They often form strong friendships with patient scholars, rangers, healers, and anyone willing to share a meal beside the water. They distrust cultures that drain wetlands, poison rivers, or treat communal resources as private possessions. Their diplomacy can seem indirect because they prefer stories, pauses, and carefully chosen questions over immediate declarations. Among other peoples, mireborn are valued as guides, scouts, herbalists, singers, and interpreters of strange natural phenomena.
