- Jaime: "You're no maester. Where's your chain?"
- Qyburn: "The Citadel stripped me of it. They found some of my... experiments... too bold."
- — Jaime Lannister and Qyburn[src]
Qyburn is among the Northern and Riverlands prisoners at Harrenhal when Ser Gregor Clegane abandons the castle and has all captives put to the sword. Qyburn, however, survives the injury at his throat and awakens when the castle is taken by the Northern army. After he wakes, he identifies himself to Robb Stark while Talisa Stark tends to his wound.
After Robb Stark left Harrenhal, Qyburn stayed behind serving under Lord Roose Bolton. He tended to Ser Jaime Lannister's badly infected stump. During this Jaime notices that Qyburn is not a Maester, because he isn't wearing a maester's chain of office. Qyburn acknowledges this, explaining that he was stripped of his chain by the Citadel and thrown out of the Order of Maesters he was conducting experiments which they felt were too "bold". 
Qyburn volunteers to join the party escorting Jaime back to King's Landing. Lord Bolton theorizes that the former Maester is doing so in the hopes that Tywin Lannister will force the Citadel to restore his chain.
