Summary House of the Dragon season 2, episode 3, "The Burning Mill," debunks a big theory about Daenerys Targaryen and her dragons. For the most part, House of the Dragon's timeline means it is very much its own thing and largely separate from Game of Thrones. However, this is dealing with House Targaryen's history, so there's inevitably some impact, which has happened in season 2.
Elissa stole the three eggs in order to eventually trade them for a ship, as she wanted to sail around the world on new adventures. The fact she is specifically referenced as having three eggs is a key point of the theory, as obviously that's how many Daenerys receives, and it is never explained what ultimately happened to the stolen eggs. It is said that Elissa sold them to the sealord of Braavos, but otherwise their fates are unknown.
Building on Daenerys' dragon eggs being the ones Elissa Farman stole, it has also been theorized they came from Dreamfyre, the dragon who, in House of the Dragon, is bonded with Helaena Targaryen. Tellingly, Dreamfyre was bonded with Elissa's lover, Rhaena, at the time the eggs were stolen, and had been noted on multiple occasions to have produced clutches of eggs, making her a strong candidate.
Does House Of The Dragon Reveal About Daenerys' Dragon Eggs From GOT Make Sense? How Does This Fit With Daenerys Receiving Them In Game Of Thrones? In terms of House of the Dragon's story in isolation, introducing Daenerys' dragon eggs does make sense. There's certainly logic in having eggs generally appear, and technically it doesn't break canon, although this reveal does not yet apply to the books.
