I imagine the main issue is the schools being different places. Kaer Morhen should be the single “school building” of the witchers. Makes sense with Geralt being a White Wolf too - nickname makes more sense if not everybody around is a wolf.
But there are clearly differences between the people with different medalions - like the cats mostly becoming assassins or swords for hire. I’d be really interested in him explaining the different medalions someday.
Edit: also makes me wonder what schools/medalions the others had. Never thought about this one, not sure if it is mentioned.
You usually invite guests to the wedding, so I’d assume bride and groom would be safe under this logic.
The parents however…
