Location: Bear Island, in the North
Motto: "Here We Stand"
Sigil: A black bear in the woods
Major members:

• Ser Jorah Mormont, son of Jeor Mormont, the former head of House Mormont
• Lyanna Mormont, the current head of House Mormont and all-around BAMF
• Jeor Mormont, former Lord Commander of the Night's Watch — Deceased

Why They Matter:
Jeor Mormont saw something special in Jon Snow from the beginning, and is the one who gives Jon his Valyrian sword Longclaw. His son, Jorah Mormont, was caught selling slaves and left Westeros to evade capture by the Starks . . . fast-forward to him becoming the closest adviser to a little someone called Daenerys Targaryen. And as Dany says, when she takes Westeros back, she needs him at her side. If he lives that long. Sniff.

Lyanna Mormont is the most recently introduced Mormont, but she's already proven that she's the kind of ruler that Jon and Sansa want on their side. It's her influence that gets Jon named king in the North.
