Hey there, Mauyn! Nice to meet you and welcome to BNW! I'm Farina, and I only play this dork right here. I don't know if they'd really have any relations since a) Aster left school when he was young (and is younger than Ion anyway, so they wouldn't have been in the same class, really) and b) he's not a noble, just an orphaned pokemon researcher/trainer.

Either way, there's always the future that they could maybe do something if you ever want to! c: I hope you enjoy your stay!
