Dany's lightbringer will be the three dragons and the glass candles. Drogo was her Nissa nissa. Viserys and Rhaego were not enough to resurrect the dragons. It took the third sacrifice to create her lightbringer.
Awesome connection between the Maiden and the sun.
Quaithe may know where to get more dragon eggs. She wants Dany to hatch them. That is what Dany will find in the east.
