Seven noble families fight for control of the mythical land of Westeros. Friction between the houses leads to full-scale war. All while a very ancient evil awakens in the farthest north. Amidst the war, a neglected military order of misfits, the Night's Watch, is all that stands between the realms of men and the icy horrors beyond.
Ned Stark, Lord of Winterfell learns that his mentor, Jon Arryn, has died and that King Robert is on his way north to offer Ned Arryn’s position as the King’s Hand. Across the Narrow Sea in Pentos, Viserys Targaryen plans to wed his sister Daenerys to the nomadic Dothraki warrior leader, Khal Drogo to forge an alliance to take the throne.
