A lot of people keep talking about Brand warging into one of the Dragons. If it was that easy, a warg would have taken a dragon a long time ago. Targayen have had dragon for thousands of years and no one ever took one warging. And I am sure it was plenty of powerful wargs during the Targayen rule...
And the horn is the only way to control the dragons. And only a true Targayen can blow the horn and live. You must be immune to fire to survive blowing the horn.
And what I remember, Dragons brought magic back into the world... Not the other way around... Spells didn't start working until dragons came back into the world. Has anyone ever wonder why? How powerful is the presence of Dragons to where three of them can make magic work again.
That alone prove it wasn't any other dragons in the world. So the sleeping dragon under Winterfell can't be true unless GRRM forgot his own statement.
I can't see any warg powerful enough to control a dragon. If there were, it would have been done when Aegon and his sisters were conquering the world.
