2) Dragons!

It's impossible not to love dragons - we want to train them to scourge our enemies; guard our gold; and carry us around in style. We're all jealous of Daenerys Targaryen's three baby dragons with their mini bursts of smoky flames and coiling tails. Unfortunately, they're not going to stay tiny for long and we may find ourselves reconsidering our position on Daenerys' pets.

On the subject of dragons, during a question and answer section at the GoT event at the Barclays Center, one fan asked writer George R.R. Martin if dragons have any weaknesses. Martin replied, as The Huffington Post reports, "It remains to be seen if anything can kill a dragon, except perhaps, another dragon. Dragons do have a pretty good record of killing each other, so, there is that."
