Hannibal appreciated Margaerys comfort and kissed her temple to return the comfort to her. He looked at Olenna and saw that she still doubted his words. "I broke every bone in his body one by one at my wife's command. He was peeled open and his ribs pulled out to look like an eagle. Then my wife commanded the final part of his punishment...we dangled him over the water as a group of sharks tore him apart while he was still alive. Every last Ironborn that was present on the islands were slaughtered. The bastards he aired were freed from their heads and those have been placed on the likes around the Red Keep. We set fire to every building and the dragons tore into the castle to destroy the bridges that provided access along with the roofs. I have set a high bounty for the heads of any Ironborn that were not on the island." He said.

He didn't hold back on the details. He would allow Margaery to admit to her grandmother what part she took as she desired.
