yea, remember the history. Children of the forest + First men (one is a stark) defeated the white walkers. then The andals from essos conquered the south of westeros but failed to conquer the north (winterfell). I believe A stark can defeat Daenery from essos.
Why would a stark need to defeat a targaryen?
