Ah the circle of the ESO forums is back to Dragons and flying mounts again <img class="emoji" src="https://forums.elderscrollsonline.com/resources/emoji/tongue.png" title=":p" alt=":p" height="20" />
I'm guessing this is meant in jest, but just in case you're serious, or for anyone not so well-versed in TES lore, then, the dragons are the children of Akatosh, the God of Time.
Dragons in TES are sentient beings with a translatable language. They aren’t beasts that can be rode by anyone with enough money. They ALLOW only the Dragonborn, their kin, to ride them temporarily.
