Theory Briefing
- Alys Rivers reveals five eggs laid by the dragon Dreamfyre at Harrenhal, a detail invented for the show and absent from the source book Fire & Blood.
- A rival theory points to Elissa Farman stealing three Dreamfyre eggs and fleeing to Pentos — long the fan-favorite origin story for Daenerys's clutch.
- House of the Dragon Season 2 already showed a separate clutch of four eggs being sent away, which fans had assumed were the future Drogon, Rhaegal, and Viserion.
- George R. R. Martin himself warned in 2018 that the egg origin is 'possible answers, not meant to be definitive,' and the show is now honoring that deliberate ambiguity.
