The Brienne of Tarth Writing meme originates from the eighth season of Game of Thrones, specifically the episode 'The Last of the Starks.' In this poignant scene, Ser Brienne of Tarth is seen diligently updating the Book of Brothers—the historical record of the Kingsguard—to complete the entry for Jaime Lannister following the Battle of King's Landing. The image quickly went viral as a reaction template to represent someone writing an excessively long response, a detailed manifesto, or a serious historical record about something relatively trivial. It perfectly captures the energy of being intensely focused on documenting facts, whether they are epic tales of knighthood or niche internet arguments.
