Bronn Blackwater

Lord Bronn is the Lord of Highgarden, Lord of The Reach, Master of Coin, and the founder of his House.
Initially a skilled and dangerous sellsword, who comes to prominence when he champions for Tyrion Lannister in his trial by combat at the Eyrie, Bronn subsequently enters Tyrion's service as his personal bodyguard, assassin, and enforcer.
His fortunes continue to gradually rise during his service in King's Landing, briefly serving as Commander of the City Watch. He is then rewarded with a knighthood for the vital role he performed during the Battle of the Blackwater, taking on the formal name "Ser Bronn of the Blackwater" later using it as the name of his house.
During Daenerys Targaryen's war for Westeros, Bronn initially assists the Lannisters. Eventually, upon Bran Stark's coronation, Bronn becomes the new Lord of Highgarden, Lord of The Reach and Master of Coin.
