[@Achronum] Probably not. I'd guess that they would want to avoid causing any sort of extra political tension. More likely to mark the mage's offspring as potentially nonviable and try to lowkey manipulate the mage into breeding with someone who doesn't have a similar condition and therefore more likely to produce foodworthy offspring. Setting up 'playdates' seems like a pretty simple solution - especially if it just means that they're letting a few different servant-mages have a free vacation or free meal together or something. Most vampire lore isn't just about blood sucking and being strong. It's also about them being masterful manipulators. I'd play off of that. Edit: Oh god. Vampires are professional shippers.
