House of the Dragon’s Season 3 premiere includes a major action sequence known as the Battle of the Gullet, which multiple outlets describe as the deadliest opening in the show’s prequel run so far. Coverage focuses on identifying which characters die during the battle in episode 1. Both sources frame the episode as a turning point because fatalities occur to major players rather than limiting deaths to minor figures. The reporting centers on summarizing the outcome of the Battle of the Gullet and confirming that the premiere delivers a high number of deaths among established characters. While the sources emphasize the scale and impact of the battle, they largely function as guides to the episode’s casualties—responding to viewer questions about “who died” and detailing the key losses that occur as the conflict unfolds. Overall, the consensus is that the episode’s battle sequence produces significant, notable deaths and sets a grim tone for the new season.
