Tyrion Lannister

Lord Tyrion Lannister was the younger son of Lord Tywin Lannister and his wife, Lady Joanna, and the younger brother of Cersei and Jaime Lannister. Born a dwarf, he used his wit and intellect to overcome the prejudice he faced, mostly directed at him from his father and sister. He served as Acting Hand of the King and then Master of Coin under his nephew, King Joffrey I Baratheon, until he was falsely accused and found guilty of King Joffrey's murder, at which point he fled Westeros and eventually found himself serving Queen Daenerys Targaryen. Daenerys soon after named Tyrion as her Hand and Tyrion served Daenerys during her invasion of Westeros and the Great War. After the Great War, Tyrion was renamed Master of Coin by King Gendry I Baratheon. Following his brother's abdication after the War of the Narrow Sea, he became the Lord of Casterly Rock, Lord Paramount of the Westerlands and Warden of the West, and ruled through the reigns of King Gendry I Baratheon and King Robert II Baratheon until his death. Tyrion sired no legitimate children and was succeeded by his cousin, Tyrek Lannister.
