I'm making a (small) family of White Court vampires for my setting, and I want to give them an emotional diet outside of the Malvora, Raith, and Skavis set. They live in LA, and the patriarch pretty much runs the entertainment industry as a legitimate front, so I'm thinking they feed off of vanity. This, however, raises an unsettling point, that the counter to that would be true confidence, a la lust vs. love, despair vs. hope, and fear vs. courage. I'm tempted to just leave it at that, to make it that much harder for the PCs, citing that in today's beauty-obsessed society basically no one has true confidence anymore. Do you think this is too subjective a Catch, and if so, can you think of anything that would fit better as a counter?

Does anyone know if a spellcaster making an oath on their power has any mechanical effect, should they break it? Looking through the books, I couldn't find anything, but I might've missed something.
