I have noticed on the imperial library "The Dominion Planets are Akatosh (eye of the warrior), Julianos (eye of the sage, and Arkay (eye of the thief). The last constellation is made up of Unstars, and is called the Snake." We all know that the three Divines I mentioned above are apart of the major group of constellations called the Guardians and that the each of 3 I believe have stars or constellations underneath them which they protect from the Snake. We also know the stars and henceforth the constellations were made when Gods or Aedra passed through one realm to Aetherius, What god or immortal being made the Snake. We know it isn't of Daedric origin because they stayed in oblivion and didn't try to leave to go Aetherius. It isn't Aedric either because all Aedric stars are accounted for and we know the Aedra are kind and not wholly evil, so they couldn't be the demonic snake. For a while I thought it was Lorkhan but he was killed and cast down before he could escape. As I said before we know the stars are Aedra, and according to the quote I have Akatosh, Arkay, and Julianos are protecting all the other stars (Aedra). What are the protecting them from. All of the evil forces we see, like Alduin, Daedra, Sithis are content with torturing people within there own realms and Nirn, and it couldn't be them because the constellations and stars are made in TES when a powerful entity is leaving Nirn, and all those evils I mentioned are in or effect nirn. Is there a unseen evil more powerful than the gods themselves that they must protect each other. Is it a possible enemy for a future Elder scrolls game.
P.S I am not sure if this is true or not but doesn't the serpent stone (Snake) only work for certain people. Thoughts and opinions.
