Game Of Thrones: 7 Things You Need To Know About The White Walkers

4. Raising The Dead

There aren't actually all that many White Walkers around, or so we're led to believe, but one of the reasons they're so powerful is that they have a huge army of wights, reanimated corpses brought back to do their bidding. They're easier to kill, but still strong, vicious, and there are vast amounts of them. Basically, if the White Walkers show up, people are going to die, and that's just new recruits for their Frozen Army of the Undead. Still, while it was clear what wights were, it was a pretty shocking and rather epic moment when, in that episode Hardhome again, we saw the Night's King show off just how easily he can make this happen. After the battle, with the surviving Night's Watch brothers and wildlings in retreat, he stands over the battlefield, raises his arms, and raises the dead. Holy sh*t! This ability makes defeating them all the harder (as if that task wasn't difficult enough), because they can constantly rebuild their army, and means that people the characters were once fighting against now become their enemy to be killed, as seen with the likes of Ser Waymar Royce, and most recently the wildling woman Karsi.
