Nice. Gives a possible answer to the question "if dragons are so damned powerful and smart, why aren't they running everything?" (Other answers are obviously possible). One unbelievably minor nit/pet peeve in the fluff:
If they are "unique" then they are not "one of the few," they are the *only*.Veroiseau, also known as Vultures of the Scales, are unique in being one of the few creatures to prey upon dragon.
