Ser Edmund Warrick was a knight of the Kingsguard during the reign of King Aegon III Targaryen.
During the regency of Aegon III, an attempted coup against the Rogare family and the Hand of the King, Lord Thaddeus Rowan, resulted in the deaths of Ser Marston Waters, the Lord Commander of the Kingsguard, and two of his sworn brothers, Ser Mervyn Flowers and Ser Amaury Peake. Ser Edmund, Ser Agramore Cobb, Ser Dennis Whitfield were given the white cloaks of the Kingsguard to replace the deceased.
