Warning: Major spoilers for the book "Fire & Blood" and "House of the Dragon" season three.In the "House of the Dragon" season two finale, Prince Daemon has a vision of his wife, Rhaenyra Targaryen, on the Iron Throne.Daemon comes to believe that Rhaenyra is the chosen one, the "Prince That Was Promised," who will unite the realm against darkness, a belief that motivates Rhaenyra herself to seize power in season three, even through grief, treason, and doubt.But her story won't be so triumphant if the series follows its source material.Although many fans will be thrilled to see Queen Rhaenyra finally materialize after she was named her father's heir all the way back in season one, actor Emma D'Arcy said the show's third season explores "a movement towards tyranny.""I think in Rhaenyra's case," D'Arcy told Entertainment Weekly, "it's a kind of religious fanaticism, actually, that starts to radicalize her position."Meanwhile, Rhaenyra's half-brothers — the primary challengers to her crown — are still at large: Aegon II (Tom Glynn-Carney), aka Aegon the Usurper, quietly fled King's Landing after he was critically injured in battle at Rook's Rest, while Aemond (Ewan Mitchell) has flown to the Riverlands with his massive dragon Vhagar to claim Harrenhal castle.
