THIS…is probably a weird question but since you mentioned planes would the Valdemars have been working on vehicle designs of any kind? The guy I'm considering happens to be a giant robot pilot and it might be hilarious for him to be a family friend by sidelining as their test pilot/driver/whatever when he's not being, idk, a mercenary or something. If not, I can always find something else for him to do or maybe consider a different character, it's no biggie!
