The sun depicted on this card is not the sun of Princess Celestia. This is also called the old sun, or white horn sun, served by some unholy crowd. When the sun was shining, he said that the ground grew up like a white horn. This sun also says that the Celestia Princess sealed it where no one else knew and made another sun. The meaning of this old sun card is not much different from the image of the present sun. It is active, rich and ambitious, symbolizing happiness. Of course, I’m not sure if that happiness would have been happy for ponies, though.
