Not surprisingly, between the Solar and Lunar pantheons, Glorantha has a lot of celestial gods.
In many real world religions, we associate the celestial beings with the benevolent gods. Frex, the words “deity” and “deva” are literally derived from “celestial” or “shining.”
The sun, the planets, the stars, the Sky Dome, and the Red Moon are all subjects of worship in Glorantha. Of those, I’d say the Sun and Red Moon are the mightiest celestial deities. The Sky is filled with shining gods.
In many cultures, the Sky Gods are ranked as the highest deities – this is certainly true in Peloria, Teshnite, and Pentans, and arguably true of many others.
The Theyalans and Praxians are unusual as they have placed Air gods at the top of their divine hierarchy, having supplanted the celestial gods in the Gods War. This is why some religions, such as Kralorelans and East Islanders, consider the Air gods to be “anti-gods” (which is one etymology for “asura” and possibly “Aesir”). That does not necessarily mean they are malevolent, but it does mean that they are rebels against the celestial hierarchy.
What can you tell me about Ehilm, the Orlanthi solar god in the west? Ehilm was not the Orlanthi solar god in the west. He is the name the Westerners gave to the Sun Disk, and the name was adopted by the sky worshiping horse herders in Ralios, the Galanin. The Galanin encountered the Theyalan missionaries two or three centuries after the Dawn and recognized their Sun as the god that the Lightbringers returned with the Dawn. Around the same time, the Theyalans interacted with the Dara Happens and were exposed to their deep celestial lore, and the Theyalans identified the Sun with the Dara Happan Yelm.
But the Malkioni continued to identify the Sun with the more abstract Ehilm (probably because to do otherwise would have required they revise spells without having the deeper lore of Yelm accessible to them).
