- "The lads caught a groom and two maids trying to sneak away with a stolen horse and some gold cups."
- ―Ser Mandon to Queen Cersei
Ser Mandon stands guard during a dinner held by Queen Cersei and Tyrion Lannister during which Cersei claims to have imprisoned Tyrion's lover/whore. The Queen orders the knight to bring her before them. Ser Mandon and one of his sworn brothers then bring in Ros, whom Cersei mistook for Tyrion's lover (which was actually Shae).
Immediately prior to the Battle of the Blackwater, Ser Mandon informs Queen Cersei of a groom and two maids attempting to flee with a stolen horse and some gold cups. The Queen orders Ser Mandon to have Ilyn Payne put their heads on spikes outside the stables as a warning.
During the battle, Ser Mandon and Ser Boros Blount remain at the side of King Joffrey as he oversees the city's defenses alongside Tyrion Lannister, the Hand of the King. When the forces of Stannis Baratheon reach the city and begin invading it, Joffrey departs for the safety of the Red Keep, at the urge of Queen Cersei, and orders Ser Mandon and Ser Boros to aid Tyrion.
Tyrion urges a host of men-at-arms to help him fight the invaders and orders Ser Mandon and Ser Boros to join him in leading the battle. Ser Mandon is also ordered to carry the royal banner. In the midst of battle, Ser Mandon attempts to murder Tyrion, right after Tyrion thought he was safe and took his own helmet off. Ser Mandon narrowly misses making a killing stroke, by mere inches – the stroke only succeeded in badly slashing Tyrion across the face. Mandon readies to kill Tyrion with a second swordstroke but is then killed by Tyrion's squire, Podrick Payne, who drives a lance through the back of his head.
While pondering over their new forced marriages, Tyrion asks Cersei whether or not she employed Ser Mandon to kill him while on the Blackwater. She refuses to reply and Tyrion suspects King Joffrey to be the one who gave the order.
During their mission to locate Sansa Stark, Brienne asks Podrick if he did anything remotely related to combat while he squired for Tyrion. He proceeds to tell Brienne how he killed Ser Mandon to protect Tyrion during the Battle of the Blackwater.

In the books
In the A Song of Ice and Fire novels, Mandon Moore is a member of Robert Baratheon's Kingsguard. Jaime Lannister considers him the most dangerous after himself because his face gives nothing away. In A Clash of Kings, Ser Mandon is not present when Cersei reveals Tyrion she has captured the whore she believes to be his lover. In the books, Ser Mandon is also killed by Podrick Payne, but Pod shoves him into Blackwater Bay as he attempts to assassinate Tyrion Lannister; Moore is dragged underwater by the weight of his armor and drowns.
Very little is known about Mandon. He came from the Vale and was brought to King's Landing by Lord Jon Arryn. Robert Baratheon made him a member of the Kingsguard, but neither Robert or even Jon loved him very much - possibly implying that Jon brought him from the Vale at Lysa Arryn's request. In turn, this would suggest that Lysa was influenced to make this request by Petyr Baelish, and therefore that Mandon may have actually been one of Littlefinger's agents.
He was never close to his fellow members of the Kingsguard. Barristan Selmy said of him that he had no friends but his sword and no life but duty. Jaime Lannister regarded him as a dangerous man, but not a man others would follow. Unlike his sworn brothers Meryn Trant and Boros Blount, who are regarded as being loyal to the Queen, Ser Mandon's true allegiance remains a mystery and is the subject of speculation. So far, it is unknown who sent him to kill Tyrion.
In the TV series, Tyrion rationalizes that only Cersei or Joffrey could have ordered a Kingsguard to kill him, but even Cersei isn't stupid enough to make such a clumsy assassination attempt: while Joffrey probably hoped that Tyrion's assassination would go unnoticed in the confusion of the battle, it would still have happened in front of his entire army and thus leave dozens of witnesses. Moreover, any witnesses would know that only Cersei or Joffrey could have ordered Ser Mandon, and it would have been more intelligent to order a random sellsword to kill Tyrion than a Kingsguard. On the other hand this hasn't been officially confirmed within the TV series, it is only Tyrion's speculation - it doesn't occur to Tyrion that an allegedly honorable Kingsguard could simply have been corrupted into doing it by almost anyone (i.e. Littlefinger, Varys, etc.).
