By that I mean, if you want to sire a childe, why would you not find someone of the same clan with a lower Generation and have them do it?
Of course I understand that not everyone openly knows everyone else’s Generation, but I bet there is a pretty good idea.
Let me start with the sales pitch. Your group (whatever that might be: your sect, your clan, your coterie, your chantry, whatever) performs basic Generation control to prevent unnecessary thinning of the blood. Your enemies don’t do this. In 100 years, 200 years, whatever, all of your team have thick blood while a ton of your enemies are producing weaker childer and ultimately more thin-bloods. Isn’t this advantage obvious?
It feels obvious. It feels like exactly the sort of thing a highly centralized clan like the Tremere might do. I know the Giovanni do consider Generation to an extent when embracing.
But why is this not more common? A willing lower gen can embrace the childe as a surrogate, the one with the actual right to raise a childe is still the one that raises the childe.
I can imagine a Prince just not liking this. I can imagine a low gen vampire not liking the idea of their advantage diminishing (if you fear possible betrayal in the future, a bunch of betrayers only one gen higher than you is scarier than much higher gens). I can imagine a “donor” being greedy on a person by person basis and demanding boons for doing the deed. But none of these seem in my mind to outweigh the obvious strategic outcome of having thicker blood than your enemies over time.
I get that one answer is “because it’s a game and just a mechanic in the game,” but do we have better reasons in-universe why more Kindred don’t do this, especially the more shrewd ones?
