Everyone in the hall exploded in approval. With Moat Cailin and the dragons, the North was practically impossible to conquer from the outside. All the northern lords that had opposed House Stark had just been crushed in battle, and despite being greatly weakened after the Red Wedding, the North now would fully consolidate behind Jon Stark. In the words of a certain House with eight thousand years of history, winter was coming. Armies could not survive in the northern wilderness during winter, as the snow could fall for days or even weeks without end. Any potential attack on the North would have to wait for spring or summer to come, and by that time, the dragons would be fully grown.
