So it's noted in the books that Lord Raith keeps his girls well under his ah... thumb by use of his abilities as a WCV. Though later, Lara manages to turn the tables and enthrall HIM.
So I'm wondering... how, exactly, is this done? Unless I missed a big slab of text in the powers write-up, I don't see anything inherent in Emotional Vampire that would allow this and again, barring my illiteracy, I didn't see anything in any of the OW character write-ups for the WCVs about a Dominate Minds power.
Am I missing something obvious here?
I don't know if it is necessarily obvious, but I have been thinking about that as well, and I choose to interpret it as follows: Lara managed to legitimately "Take Out" Lord Raith using the normal conflict rules - using her Incite Emotion/Feeding/etc. - and opted that his "death" be a mental one, leaving him basically a vegetable, under her control, so she could leave him as the figurehead. Either that or Lord Raith Conceded and accepted that state.
In short, the Taken Out/Concession mechanics.
Well I think someone mentions in Blood Rites that WCVs settle disagreements by pitting their demons against each other, so I'd expect that this sort of manipulation is inordinately effective when it's between two WCVs.
Also, please note that Lara was able to overcome her previous defeat by her father to eventually turn the tables on him, so it isn't like it's a perfect eternal thrall-maker.
I agree with Richard's take on this. Lord Wraith used Lasting (Potent) Incite Emotion to mentally take out each of his children (probably many times), choosing to inflict an extreme consequence and thereby changing one (or more) of their aspects to make them more obedient. This is reasonable given that mental attacks "change who you are". I imagine the results would be along the lines of "I exist to please Daddy" or "I would be nothing without Daddy's guidance" or "I'd rather die than disobey Lord Raith".
While this wouldn't be as all-consuming powerful a result as Domination would create, it has the advantage of leaving the victim fully capable of acting on their own initiative, but with a soft control in the form of needing to pay Fate to act counter to the being that he now has become. Given that the victims are all (or nearly all) negative refresh 'monsters', they have a particularly hard time overcoming those aspects. And given the nature of the aspect, even an attempt to 'heal' the aspect would be potential compel-material.
In terms of relating the game mechanics to the series, it's ironic that Harry Dresden himself may have provided the Fate points Lara needed to overcome Lord Raith's control...
