Sansa Stark and Jon Snow visit Bear Island to recruit House Mormont to their army, intending to march on House Bolton and retake Winterfell. She replies to a letter from Stannis with a missive asserting her continuing loyalty to House Stark. She refuses to pledge allegiance to Stannis Baratheon against House Bolton. Lady Lyanna Mormont rules the House from Bear Island. Roose Bolton is named Warden of the North by King Joffrey, meaning that House Mormont now owes him allegiance, lest they remain enemies of the Iron Throne. At that massacre, Dacey Mormont dies valiantly protecting Robb Stark. The Northern army including the forces of House Mormont are wiped out, apart from the turncoats in Houses Bolton and Frey. They orchestrate a massacre behind the facade of a wedding at the Twins. House Frey takes vengeance against Robb for breaking their marriage contract, in collusion with his bannermen in House Bolton and his enemies in House Lannister. Maege no longer appears on King Robb's war council. Maege and the other Northern lords declare Robb the King in the North after the execution of Eddard Stark. Maege serves as a member of Robb's war council in the ensuing conflict. Eddard's son Robb Stark calls his banners, and Lady Maege Mormont answers with a force joining Robb's army.

Lord Eddard Stark is imprisoned by the yet-to-be-crowned King Joffrey Baratheon.

The House has found it difficult to shake off this disgrace, especially Jorah's father Jeor Mormont. House Mormont is one of the oldest and proudest Northern Houses, but their reputation and honor have been tarnished somewhat by their former lord, Ser Jorah Mormont, who committed the inexcusable crime (in Westeros) of dabbling in the slave trade. The Starks are said to have won the lands in a wrestling match between King Rodrik Stark and an ironborn. House Mormont's ancestral home of Bear Island is said to have been a gift from their liege lords House Stark, which earned them the everlasting loyalty of House Mormont.
