Ok so this isn't so much a headcannon but probably a funny and maybe one of the most awkward conversations a person could put the WoL in. That being a conversation between the WoL and Brother E-Sumi Yan or with any other padjal who became THE whm and ended up becoming a parent to a child born as a padjal. Could you imagine how that conversation would even go? "Sorry WoL, but rules are rules. You'll have to hand over the care of your child to the Conjurers guild so we can teach them how to use their powers." With the WoL just giving them a "Say what now?" look. Sure the Elementals haven't ever directly tried to speak to the WoL so we don't know if the Echo could help in understanding them. But we do know that a Whm WoL would not only already be apart of the guild, but probably could do a great job in making sure their child wasn't getting eaten by a voidsent. And after our time with Zero probably could probably ask her and "Golbez" a favor to make sure on their end that no voidsent they know will even think about trying to eat the WoL's kid.
