9. The Fist of the First Men
When the men of the Nights Watch, led by the Old Bear, left the safety of Castle Black for the frozen lands beyond the wall they had one objective: defeat Mance Rayder and his forces. But a sudden invasion of an undead army would force anyone to change their plans pretty sharpish. With the tiny force of Nights Watchmen acting as pretty much the last line of defense against this army of Wights, the civil war suddenly seems a distant nagging worry. Here is the real threat, with the Crows at the Fist of the First Men. Season 3 will undoubtedly explore this last bastion motif further and if its anything like the books it promises be pretty spectacular indeed.
