4. Davos Seaworth
The Onion Knight provides the court of Stannis Baratheon with just the right seasoning. This former smuggler turned trusted advisor isn't afraid to tell it like it is to his monomaniacal boss, or to question the creepy cult the Red Woman has formed around him. Actor Liam Cunningham gives him a rich, rolling voice as salty as the sea by which he lives or dies.
