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:
Veroiseau, also known as Vultures of the Scales, are unique in being one of the few creatures to prey upon dragon.
If they are "unique" then they are not "one of the few," they are the *only*.
