Jason Lannister

When Princess Rhaenyra Targaryen visited the Westerlands in 112 AC, Ser Jason and his younger twin, Ser Tyland, vied for the princess's hand during a banquet at Casterly Rock. Both twins showered her with gifts, without success. When the Dance of the Dragons began in 129 AC, Ser Tyland served as Master of Coin to King Aegon II Targaryen. His brother's close association with the Iron Throne and his favored position at court brought Lord Jason into the Dance, supporting the Greens against Rhaenyra's claim. Lord Jason assembled a formidable host of a thousand knights and seven thousand archers and men-at-arms. Prince Aemond Targaryen had Jason and his troops descend the riverlands via the Red Fork. At the Battle of the Red Fork, the river lords rushed to meet Jason's army in battle. The Westerlanders attempted to cross the river three times, but were prevented. On the third attempt, Lord Jason was mortally wounded by Pate of Longleaf. While Jason lay dying from his wounds, Ser Adrian Tarbeck took command of the men of the west and destroyed the army of the river lords. Lord Jason died of his wounds shortly afterward, leaving Casterly Rock in disarray. Jason was succeeded as Lord of Casterly Rock by his son, Loreon. For his actions, Pate was knighted by Lord Petyr Piper and nicknamed "Longleaf the Lion-Slayer". Jason's widow, Lady Johanna Lannister, defended the western lands from the Red Giant Squid, Lord Dalton Greyjoy. With the bulk of the Lannister force in the riverlands, the ironborn descended upon the poorly defended western lands, sacking Lannisport and seizing hundreds of women, including Lord Jason's favorite mistress and his natural daughters. Jason was married to Lady Johanna of House Westerling, with whom he had five daughters, including Cerelle and Tyshara, and a son, Loreon. Jason also had illegitimate daughters with his favorite mistress.

Jason was tall, with golden hair, emerald green eyes, and a dashing demeanor, like his twin brother Ser Tyland. Jason is a hunter and a warrior. He is arrogant and proud.
