An interesting point to roll with, Moon. The next question, of course, which we haven't asked is, "How do lesser races react to this breed of Ubermenschen?", and "How does this 'Superior' race treat the lesser races?" Many things will be dictated by the degress of personal interaction, racial pity/patronizing/suppression, etc, and it can be argued that this form of interaction can be more important than the actual qualities of the race itself.
That said, in the Kallisphere, the race appropriate to the role is known to the people at large as the 'Ancients'. Uniformly, they are tall and slender, with golden skin and silver hair, and it is the rare Ancient that is not attractive to the human eye. Rarely stronger than the human, the Ancient is however, more graceful in her actions and thought, showing a harmony of elegance through out. Exceptionally long lived, the years being exceptionally light to the body, a given Ancient will tend to be wiser than the humans or others that surround him, by sheer weight of years. Together, these attributes mean that the Ancient tends to be more capable at tapping the Gift of the Gods known as Magic. As they grow to be elders, it is not uncommon for them to truely begin to understand the Gift of the Gods, even unto the point of being able to give the Gift themselves! To give the Gift in this manner drains them horribly, for despite their perfection, they are mortal, and the Giving of the Gift requires the infinite, unending Lifespark of a God.
The Ancient tends towards cultivating outward harmony around himself, and members of their rare race can often be found amoung the humans will out as priests, sages, witch doctors and wizards. Often, behind the king of a prosperous land will be an Ancient sensechal, yet it is rare to find an Ancient in direct command over other races - They have learned that the differences can become the focal point for intense hatred. Again, because of that harmony, it is rare for an Ancient to be truely evil or depraved, for the Sphere itself is suffused with the gentle aura of the Mother, and they can feel her power and gentle love in the way that no human can. Still, it is not unheard of for one to be misguided, or to fall under the influence of a creature with a darker, twisted aura.
Edit: The Ancients have no society of their own, and are instead adrift as single men, women, and small families throughout the kingdoms of the other races. History taught them the twin fruits of jealousy and patronizing, and so they wield no political or military power of their own. In the deep, deep past, times immemorial, some amoung them played at being demi-gods, and so the race of Dragons resulted.
