Ser Owen Bush was a knight of the Kingsguard during the reign of King Maegor I Targaryen.
When Queen Alyssa Velaryon escaped from King Maegor I Targaryen's imprisonment, the king ordered his knights to give her son, Prince Viserys Targaryen, to his torturers to discover where she was hiding.
Queen Ceryse Hightower died suddenly, so a rumor went around the Red Keep that she had said something to offend Maegor. It was widely believed that the king had ordered Ser Owen to remove her tongue, but Ceryse's struggles caused his knife to slip and slash her throat. Most historians believe this was a slander concocted by the king's enemies to damage Maegor's reputation, however.
When Maegor suspected Queen Tyanna of the Tower of betrayal, he had Owen and his sworn brother, Ser Maladon Moore, bring her to the dungeons, where she confessed.
Maegor the Cruel gradually lost political support, resulting in a rival threat in his nephew, Prince Jaehaerys Targaryen. Two of his Kingsguard defected to Jaehaerys, and Maegor lost a third guard when Owen was found dead outside a brothel in 48 AC, his member cut off and stuffed in his mouth.
Maegor: Chain him in a black cell and question him sharply. Ask him where his mother has gone.
Owen: He may not know.
Maegor: Then let him die. Perhaps the bitch will turn up for his funeral.
