long story short, their parents died when he was nine and she was significantly younger. (somewhere between one and five or so.) he was remanded to alliance custody, and enrolled in a military academy, she was put into the system and adopted by some lovely family, i'm sure. she probably has/had little to no memory of him, but he’s been lowkey looking for her for years. it’s mostly just a vague idea, we could def work out the fine details, though.
