I'm aware of that, but family relations have a tendency not to be straight forwards; For example, Zyphus and Juno aren't exactly on the best of terms relationship wise due to a conflict of personality, whereas Zyphus and Kelda's relationship is much stronger. In turn I can see Soulless being a favored nephew of Fay. Considering the Mistress politics and their efforts to one up each other, would it really be that surprising to see them offer a favored nephew or niece a little something that they might wish to use over the present presented by their own mothers?
Even so, as the mothers are GM-NPCs, its the kind of thing you run past said GM, not just decide on a whim. S'called Metagamin.
