Thanks! I was going for a medieval woodcut look for the cosmology diagram. Do you think Beth will hire me to make their book art for TESV?
Julianos is one of the planets mentioned in that article in the Dwemer Orrery. Because both it and Akatosh on the opposite side maintain constant relative positions as the orrery moves, they're assumed to be the dominion planets. Also, they match up (almost) when you look at the dominion planets and the stars, so I think those are correct. As for the others, I'll shuffle some about:
Mara, Goddess of Love, patron of the bountiful earth, and source of mortal compassion and understanding. Nearly revered as a universal goddess, her origins are in mythic times as a fertility goddess. In Skyrim, Mara is a handmaiden of Kyne. In the Empire, she is Mother-Goddess, worshiped at the Benevolence of Mara. She is sometimes associated with Nir of the 'Anuad', the female principle of the cosmos that gave birth to creation. Depending on the religion, she is either married to Akatosh or Lorkhan, or the concubine of both.
I think I'll move Mara to Zenithar's position, and Kynareth to Stendarr's position. That way, Kynareth is orbiting Nirn, and Mara is orbiting Kynareth as her "handmaiden".
Member of the Eight Divines/Nine Divines, Zenithar is understandably associated with Z'en. In the Empire, however, he is a far more cultivated god of merchants and middle nobility, Patron of Work and Commerce, the deity of wealth, labor, commerce and communication. His worshippers say, despite his mysterious origins, Zenithar is the god 'that will always win'. His priests are said to have shown that the way to peace and prosperity is through earnest work and honest profit, not through war and bloodshed. He is also said to have associations with Kynareth, as Zenithar's workers take and profit from Nature of Kynareth. It is also said he is most in touch with the mortal world. Zenithar created the Mace of the Crusader for Pelinal Whitestrake, to help him defeat Umaril the Unfeathered.
Because Zenithar is associated with Kynareth, I'll keep him in the same orbital group, since I'm changing that large planet to Kynareth.
God of the Eight Divines/Nine Divines, Stendarr has evolved from his Nordic origins into a deity of compassion or, sometimes, righteous rule by might and merciful forbearance. Stendarr is the inspiration of magistrates and rulers, and the patron of the Imperial Legion. He is said to have accompanied Tiber Septim in his later years. In early Altmeri legends, Stendarr is the apologist of Men. Stendarr created the Gauntlets of the Crusader for Pelinal Whitestrake, to help him defeat Umaril the Unfeathered.
I'll move Stendarr to Mara's position, orbiting Nirn.
I'll also remove Aka and Shor from Aetherius.
