Unwillingly

Malii'evarir: If you pick a child up out of a bush, it is yours. Finders keepers. Family is a loose term, and having grown up in a nomadic tribe people entered and left the 'family' all the time

Einar: Blood and vows make a family. He's a simple man, not a lot going on upstairs

Avyn is a member of one of the original Seeds from when 'Ame Seeds were first implemented - Calithil (now Acaele'thil). Unlike the other seeds that gained new members through trials etc, Calithil was very strictly bloodline with the extremely rare honourary title gifted (maybe 2 in existence). As a result, she only considers her family to be those who are blood, or those related via marriage who make an active effort to be in her life. This helps cut out the ridiculous amount of "family" gained through marriages into other seeds etc.

Noruiwyn has forged her own family with a daughter she adopted over two centuries ago. As a mortal, prior to her original ascension, her family was of marriage and legitimate children. After ascending and having her soul warped, she abandoned this family and instead developed a 'found family' through the form of very close connections. It is interesting to see her perspective on family adjust the more she reflects on her path and comes to new realisations!
