Known for their kindness, uriasi live in open, matriarchal clans in the mountains. They keep their homes in caves, but have farms throughout the woods near their caves. In their legends, they once ruled the world because they knew Her Name, but they intentionally hid Her Name away and became peaceful farmers to protect the world.

In their clans, children are raised communally and all major property (food, land, water, shelter) is shared. Children choose their role in the clan by the age of 16, and they hit adulthood a few years later at their final growth spurt around the age of 19. If they don't hit their growth spurt, they meditate upon their Names until it happens. Adulthood means taking on new responsibilities for the clan, and they take this very seriously. Courtship is a game of secrets and intimacy that results in many couplings. All relationships among them are open and fatherhood is an unknown concept.

The major roles in a clan are farmer, hunter, guard, weaver, builder, carver, digger, healer, and water-bearer. The elders of each of these roles form a council that runs the clan. Gender is not usually a consideration among uriasi.

Because they live in the mountains, uriasi can see flooding in the valleys. They always go down as a clan and save those affected by the flooding if they can.

Uriasi celebrate seven festivals each year: new year (or "tree-lifting day"), plowing day (or "meeting the human nations day"), gold day (or "countilg the village stores day"), harvest, and three ancestral days. During their lifetimes, uriasi celebrate major feasts for each of their Names. Festivals always include games, meeting with other clans or nations, and feasting.
