Also the silver eyes thing is only one brood of vampires I believe, Diana's if I'm not mistaken. The others two broods have differing characteristics.

Nah, going with what Brovo written in the first LoR2, it's common vampires trait:
[quote]Vampires themselves are universally identifiable with their silver eyes, though some use magic to hide this trait. Their fangs can retract which, unless closely examined, makes it difficult to tell whether they are or are not vampires. Furthermore, Diana’s brood in particular, tend to merge well in the upper echelons of society and gain favour with others.[/quote]
