Jaime Lannister is one of the best swordsmen in the Seven Kingdoms. He is a renowned soldier and a member of King Joffrey's Kingsguard, an elite cadre of seven knights dedicated to protecting the king.

At a young age, Jaime made a name for himself as a squire with a talent for battle, which he honed in tournaments and jousts. He learned quickly that fighting with honor was second in importance to winning. As Queen Cersei's fraternal twin, the two always shared a very close bond, which escalated into a secret sibling affair as they grew older. This affair was discovered when Bran Stark discovered the two in the abandoned tower in Winterfell; a discovery which Jaime made Bran pay dearly for.

In the years before Jaime served in Robert's Kingsguard, he served as the Mad King's bodyguard. When Robert's rebellion crushed Rhaegar Targaryen at the Trident, Tywin Lannister, the Hand of the King, seeing all lost, gave Jaime the order to murder King Aerys. Jaime does this, which earns him the name 'Kingslayer.' Robert, in order to keep the Lannisters happy, allows Jaime to keep his position as a member of the Kingsguard after he ascends to the throne; a position which allowed him to be near Cersei as well.

When the war of the five kings erupted, Jaime was sent off to lead the Lannister forces in battle, where he was captured and taken prisoner at the battle of Oxcross by Robb Stark. He was held prisoner for months until Catelyn Stark agrees to free him on the condition that Brienne of Tarth bring him to kings landing to trade for Sansa Stark and, if possible, Arya Stark as well.

Jaime has an interesting relationship with his family, to say the least. Besides the 'unconventional' relationship with his sister, he is the only direct family member who cares for Tyrion at all. Despite Tyrion's birth resulting in the death of his mother, Jaime doesn't seem to resent his brother, even when his father and sister hold Tyrion completely responsible. Aside from his immediate family though, Jaime seems to have little regard for extended family members - as he kills a distant cousin to try and escape from the Stark's prison. This is in contrast to traditional Lannister family behavior, which dictates that Lannisters must take care of each other under all circumstances. Likewise, he doesn't seem too concerned with the fact that he has three children that need to be taken care of. The entirity of his emotions seem hopelessly devoted to Cersei; while everything else around him is deemed completely unimportant.

Interesting Facts:

♦  In season one, Jaime went against the Kingsguard code of conduct for  by dueling Eddard Stark in King's Landing.

♦  After Jaime slays King Aerys, he sits on the Iron Throne. When Eddard Stark arrives and sees him, he orders Jaime off the throne.
