The Biggest Game of Thrones Conspiracy Theory Is More Likely After House of the Dragon ...

Theory Briefing

• The Grand Maester Conspiracy theory holds that the Citadel secretly engineered the extinction of dragons to shift power from Targaryens to scholars and lords.
• House of the Dragon's new story details are said to add fresh evidence that makes this decades-old fan theory feel more plausible than ever.
• The theory reframes dragon extinction not as tragedy or accident but as a deliberate, institution-driven power grab hiding in plain sight.
• If the Citadel did orchestrate it, the maesters' trusted role as advisors gave them the perfect cover — access without suspicion.
