Major members:

• Ser Davos Seaworth, former Hand of the King to Stannis Baratheon

Why They Matter:
Davos has been through a lot following Stannis for so long, and he believes in Jon Snow as a man worth following now. He's proven to be an asset to Jon and Sansa in their campaign to unite Northern houses, and he's got the experience to back it up. If you're going to plan a war, Davos Seaworth is a man you want on your side.
