We know jackshit about Lords and Muses, for all we know Lords could be a wimpy class (Personality-wise) and Caliborn and Calliope were just examples of really shitty Lords/Muses

I mean, yeah but even shitty shows of a Class tell us a LOT about said Class, such as most of the Dancestors. Knowing about their powers as well sheds a lot of light on the Class itself. We barely know anything about ANY of the Classes, but we can definitely infer through context clues, comparisons and examples given to us by the text.
