The Complete Guide to All 21 Major Houses on Game of Thrones

Location: The North
Sigil: Four chains linked in the center on a dark red background
Major members:

• Lord Smalljon Umber, son of the Greatjon — Deceased
• Greatjon Umber — Deceased

Why They Matter:
House Umber had been sworn to House Stark, and so Bran sent Osha and Rickon to the Umbers back in season four where he thought they could be safe. However, Lord Smalljon Umber asked for the Boltons' help in fighting the wildlings in his land and turned over Osha and Rickon to Ramsay to sweeten the deal. AND he killed Rickon's direwolf. D*ck move, man.
