[@Zeroth]I was originally thinking that it’d be the father who was a Kaides, but I think it’d be spicier if it was the mother who was the Kaides instead. Something something, popped outta the womb and looked nothing like (read: cuter than) the husband ever could. Probably still will have a similar kinda setup though, where a knight of House Kaides spends a celebratory last night of a long deployment at a brothel before returning home to their family and spouse. Nine months later and oops, that’s not your kid!

Probably wouldn’t be a ‘son’ of the Patriarch in that case; more associated with one of the adult kids.

I’ll leave you to flesh out ze Young Master if you want, but they’d be associated with the Kaides. I had approached it as the angle that Ferrucio himself was allowed to stay in the House basically to serve as a second set of hands for the proper heir; in that case, the Young Master would be his older sibing/cousin/etc. I was generally thinking that they’d be the ignoble sort who was the one that put out the hit on Estelle, for two tigers cannot roam the same mountain, but that’ll be kinda up to OwO.

The Swiftblades could be a non-elite unit of House Kaides yeah. I was thinking they’d be a frontier force that basically deals with all the monsters plaguing the borders of the kingdom. A protector of the commonfolk, who ride on swift steeds and cleave through calamities with blessed steel, answering the demon armies that are too much for ragtag adventurers and too small to mobilize the army.

Think it’d be part BEEG PR for Kaides and part “this is where idealistic knights go to chase their dreams”.
