There's a valour to them, despite their evil. You get the feeling when you face one that he's fighting you for the thrill of battle as much as anything else, not just because he's been ordered to attack by some master. There are few foes as deadly, though. Most of my lads are tough old veterans— hard to kill, because they know how to use their shields and armour to best effect as well as their blades. After a fight with Wights, though, I know I'll have lost good men.
