Marriage in an official sense in Aianar is in general limited to the upper castes of society, as it constitutes the union of two noble bloodlines. Mating in the unofficial sense, on the other hand, is popular; besides singular pairing, polygamy is a widely accepted practice and carries no negative connotations among the lower classes.

Although pairing is mostly the same in its strictest definition across Nor, the details and rituals of it are radically different between different cultures.
