Question: Choosing Moeities

[anxious_songbird]

Not much is actually said about moeities in Ursula's works outside of the marriage aspects, despite the text saying it has to do with ancient religious reasons. How do you decide on what moeity a character is in?

Do you just go by gut instinct or go with what aesthetically makes sense? Do you create your own worldbuilding around it or are you lax with it? Are there in your headcanons markers of what moeity someone is in and if so what are they?
