Tybolt Lannister

Before inheriting Casterly Rock, Ser Tybolt Lannister entered the Ashford Tourney as a challenger. He chose to face Ser Androw Ashford first and beat him.

In a later tilt he was unhorsed by Ser Jon Penrose, but kept fighting with nothing but his shield and won that round anyway.

Tybolt was the eldest son of Lord Damon Lannister and Lady Cerissa Brax, and had a younger brother, Gerold. He inherited Casterly Rock when the Great Spring Sickness took his father, and ruled with Gerold as his closest councillor.

He married Teora Kyndall, with whom he had a daughter, Cerelle.

In 211, Lord Dagon Greyjoy struck at the Westerlands and plundered much of the wealth of Fair Isle. Tybolt answered by ordering a fleet of his own built, meant to strike the ironborn at sea and carry the fight to the Iron Islands.

When King Aerys I Targaryen sent no help from the Iron Throne, Tybolt turned to Lord Beron Stark of Winterfell, and together they carried on the war against Dagon.

In 212, though still a young and healthy man, Tybolt died under circumstances that were never explained. Casterly Rock passed to his three-year-old daughter Cerelle, with Gerold ruling as regent.

Cerelle died before a year had passed in the role, and Gerold inherited Casterly Rock after her. The two deaths coming one after another left many suspicious of him.
