Tyrion Lannister
Ned's arrest pits the Stark and Lannister forces against each other, and his execution causes a civil war later called the War of the Five Kings. Tyrion Lannister eventually returns Ned's bones to his widow Catelyn, but it is not confirmed whether they ever arrived at Winterfell. He is mentioned in a flashback along with his friend Robert Baratheon in the follow-up novel "A Clash of Kings".
