Magenta's Sire.
A 9th Generation Blue-Blood. Very business oriented, very masculine (in character, not in appearance - she proudly adheres to the actor-koosit standard), very gay.
No one ever expected her to have a Childe, but I guess she fell for Magenta exactly at the right age, whatever that would be for vamps.
Magenta hasn't heard of her since the second war in Europe.
