Exalted: The Black Heart of the Isles
Each Mandalan becomes a member of a caste upon adulthood (In the rite of Caste Assumption, usually age 14), the castes are Fisherman, Merchant, Priest, Craftsman, Hunter and Spiritchild. With the exception of Spiritchild a child may choose to select the caste of either of their parents, though most apolitical marriages are of two adults of the same caste. Spiritchild children of the correct gender for their order (e.g. female for Skydaughter, male for Sandson) are automatically a Spiritchild with no choice of caste, those of the incorrect gender either default to their non-Spiritchild parent’s caste or ritually neutered, depending on how much Spiritblood they exhibit. It is forbidden for a Sandson to marry (or couple with) a Skydaughter.
