The son of Lord Commander Jeor Mormont, Jorah now lives in exile in Essos. The knight fled Westeros in disgrace for slave trading, a crime he engaged in to support a selfish wife who has since left him. Mormont originally joined Dany's company to spy on her in exchange for a pardon. Now devoted to Dany, he saved her from an assassin who was hired based on information Jorah had provided.
