Tytos Frey

As Ser Jared's eldest son, Tytos holds a notable place among the sprawling Frey brood, though the sources say little of his life before that night.

In 299, amid the slaughter that erupts at Edmure Tully's wedding, someone splits his skull with an axe. He dies at the Twins, inside the stronghold of his own house, with no one yet knowing whose hand struck the blow.

Only later is it learned that the man who killed him was Sandor Clegane, the Hound, present that night at the Twins. The account does not say what brought him to Tytos, only that it was his hand that ended him.
