Adoption is viewed on Praxis as one of the greatest virtues. Orphans without family are adopted so that they can grow up as responsible adults, though many Mamonme and Celestials aren't shy about adopting boys and marrying them when they come of age. Girls of any species are raised as well as their parents are capable, though species differences might dictate a tutor for some practical issues like learning to fly or handle magic.
Mutual adoption Edit
It is not uncommon, especially amongst Mamonme, for very dear friends to consider mutual adoption. By recognizing one another as sisters (and rarely, as brother and sister) they create a family bond. Though there are legal benefits from this, the main focus of mutual adoption is to explicitly state that the adopters trust each other implicitly.
