The wight was presented by Jon, Daenerys, and their followers at the Dragonpit Summit before Cersei, Euron Greyjoy, and their entourage. However, the Night King managed to kill one of her dragons, Viserion, during the rescue mission.
The mission nearly failed but Daenerys, atop Drogon, rescued Jorah Mormont, Tormund, Beric Dondarrion, and Sandor Clegane, while Jon fought off wights to allow Daenerys and the others to flee.
In accordance with the plan, Jon and a team ventured beyond the Wall to capture a wight. Cersei held the Iron Throne after the War of the Five Kings and agreed to a parley in King's Landing. Daenerys's Hand, Tyrion Lannister, came up with a plan to capture a wight so they could convince Queen Cersei Lannister to agree to a truce during the Great War. He negotiated with Daenerys Targaryen during her invasion of Westeros, eventually cultivating an ally in her. Jon Snow, King in the North, prepared the North for the White Walkers, who rose again after thousands of years during his time in the Night's Watch. Presumed heavy losses for Free Folk, Night's Watch, and Brotherhood Without Banners.
