Lord Commander Hoare was a member of House Hoare who served as the Lord Commander of the Night's Watch during Aegon's Conquest. His given name has not been revealed. He was a son of King Halleck Hoare and a brother to King Harren Hoare.
Lord Commander Hoare led the Night's Watch when Aegon the Conquerer invaded Westeros with his dragons. The Lord Commander's brother was Harren the Black, King of the Isles and the Rivers. Although Lord Commander Hoare commanded ten thousand swords at the Wall, he remained loyal to the Watch and did not intervene when Harren and his sons were slain by Aegon's dragon, Balerion, during the burning of Harrenhal.
