House of the Dragon showrunner Ryan Condal spoke at Shoreditch Town Hall in East London, telling the audience that Season 3 would fulfill promises made in Season 2. Condal specifically highlighted the Battle of the Gullet, a large-scale naval conflict from George R.R. Martin's source material, as the opening sequence of the new season.

Condal described the battle sequence as unlike anything that has ever been done in television before. He did not provide specific details about the production methods or scale, but the battle is expected to be a major set piece for the season premiere.
