aren't the girls/farran/cronan all related?
okay, so here’s the deal.
there’s the 5 sisters which are the guardians of the portal. emily (which is the name of emily’s grandmother, one of the sisters. she was named after her grandmother), skyra, quartzine, the water guardian (unnamed), and the fire guardian (also unnamed), are all sisters. there were other elves that existed, they just all happened to be sisters.
quartzine is cronan’s mother, and emily is the granddaughter of emily (the elf), so that makes cronan her….weird uncle.
azari, aira, naida, and farran are NOT related and NOT descendants of the five sisters. (aira and farran even had crushes on each other in canon) they are childhood friends!!!
tidus, sira, ragana, johnny, and the main gang are also around the same age, as ragana and johnny were in the same class as farran/azari/naida/aira.
tidus and sira were a thing i guess, and a couple of the girls were shown to be ‘attracted’ to tidus, much to the annoyance of farran.
unfortunately, it says on the lego website that rosalyn was also a decedenant of one of the five sisters, which should be a mistake considering in the new series by studio mir, they’re (cronan and rosalyn) shown to be a couple, so yikes on lego’s part.
i hope this was helpful to you!
