[LDiCesare]

A Marverni->Marignon transition still loses blood in the process of EA/MA (most notably the blood sacrificing ability).
Man doesn't really come from Tir na n'Og, since Tir na n'Og turns into Eriu (these being Irish whereas Man is more Welsh/Breton and Marverni Gallic).
I also forgot to add Ulm to the list of nations gaining Blood in the LA.
