Not long ago I heard the egyptien legend of Seth, Re and Apophis:

Re’s, the sun god’s biggest enemy was Apophis, the god of evil, who usually had the form of a serpent. It said that Apophis could hypnotize Re and it’s ship’s crew. Only Seth, the god of chaos was the only one who couldn’t be hypnotized. So he got the task to protect Re from Apohpis.

Of course as MLP:FiM fan, I had to think right away about Celestia and Discord. And this picture happened.
Why does the snake has similar eye of Sombra. Well because of dark magic and everything.
