Tytos Lannister

"I'm do what must be done for the realm. The realm needs strong men led by an even stronger king. A new dawn is upon Westeros, father."

-Tytos to Arthur

Tytos (470 AC - ) of House Lannister is the current King on the Iron Throne and Lord of the Rock. His full title is Tytos of the House Lannister, First of His Name, King of the Andals and the First Men, Lord of the Iron Throne and the Rock, Rightful Ruler of the Seven Kingdoms, and Protector of the Realm.

Background
Tytos Lannister was the second son of Arthur Lannister. As a child, Tytos followed in his father's footsteps, becoming a cunning, ruthless prince with a keen mind for political diplomacy and intrigue. He quickly overshadowed his older brother and heir to the Rock, Tybolt Lannister, as Arthur's favorite son. Tybolt's position as heir to the Rock and potentially the Iron Throne always angered Arthur, but especially enraged Tytos, who believed he should have been born first.

The Typhoon of Steel
Tytos leaves Casterly Rock at Arthur's request to aid in the Iron War. The entrance of House Hightower and House Frey has stretched Lannister lines thin; while Tybolt has been sent to "lead" the much more secure front against Ryman Frey along with Lord Patrek Westling, Tytos is given the much more difficult task of subduing Reginald Hightower.

Tytos, having studied the mistakes his grandfather Loren committed in Loren's War, begins his plan. The Lannister fleet is expanded in order to fight the formidable Redwyne fleet, and rather than needing to ship soldiers across the sea like Loren had to, Tytos secures passage through the Reach thanks to a marriage between him and Maude Tyrell, the younger sister of King Garlan Tyrell. Garlan even enters the war when Tytos promises him the lands of House Hightower. Oswell Tarly, a third son of Horn Hill, joins Tytos's ranks, and Tytos is quickly impressed by the young man's skill.

The news of the alliance is kept secret, and Tytos tricks Reginald by pretending to follow Loren's path and ship soldiers across the sea. Even with this, Tytos expects victory over the Redwyne fleet. In the Battle of the Shield Sea, the Lannister fleet is surprised when the fleet of the Iron Islands arrive. The Lannister fleet is dispatched, and Reginald and his bannermen celebrate victory. The victory is short lived, however, when news arrives that the Lannister-Tyrell armies have invaded and are pillaging everything in their path.

At this same time, Tytos makes plans for his eventually ascension to king. He bribes Patrek Westerling into killing Tybolt in the confusion of battle. However, Patrek decides to kidnap Tybolt instead, believing he will catch a good price with a valuable hostage. Both men are assumed dead following the Battle of the Golden Tooth.

The Lion's Dawn
With both Byron Mallister and Davos Baratheon pledging fealty, Arthur Lannister felt he finally had enough power to restore the Iron Throne. Taking the swords of the kneeling storm and river lords, Arthur orders the construction of a new Iron Throne. Arthur and Tytos head to the destroyed King's Landing to see the decayed original throne. In the ruins of the Red Keep, they see the monstrous chair reduced to nearly rubble. As Arthur sits on it, he turns around to see Tytos aiming a crossbow at him. Before he can protect his king Lionsguard Ser Paxter Kayce is killed by an ambush by Tarly's sellswords. Tytos kills Arthur with a quick bolt to the forehead. Tytos removes his father's body and sits on the ruined Iron Throne.
