World
The Rimaeri are the people of the Rim. Outsiders may call them Rimmers, but among themselves they are Rimaeri.
The outsider word points at where they live. Their own name points at who they are: people shaped by crossings, weather, fairness, movement, and the work of keeping relation alive across difference.
Rim thread
Movement matters in Rimaeri life, but movement alone is not the point. Routes can connect people, goods, duties, remembrance, and shared knowledge.
Fairness matters because crossing and exchange affect more than one person. A route used badly can decide who eats, who waits, who is heard, and who pays the cost.
The Rim teaches movement. The Rimaeri show how people live inside it without treating movement as permission to take whatever can be taken.
Daily life
Children learn the Rim through ordinary tasks: watching paths, listening to weather, taking messages, counting turns, keeping agreements in mind, and noticing when a route feels different from the day before.
Knowledge is practical. A child may learn which cloth-pattern belongs to which route-house, which call means wait, and when a promise needs more than one witness.
This makes Rimaeri childhood active without making every child heroic. Much of the learning is small, repeated, and useful.
Names
Rimaeri is the name used among the people themselves.
Rimmers is an outsider word. It can be ordinary, careless, affectionate, dismissive, or rude depending on who says it and why.
The site should normally use Rimaeri. Use Rimmers only when the outsider point of view matters.
Routes, weather, exchange, shared knowledge, and rhythm shape daily life. Fairness and remembrance can matter as much as possession or fixed boundaries.
Rimaeri life is varied. Families, places, duties, and ways of holding history can differ while still sharing a sense of belonging to the Rim.
