‘House of the Dragon’ Season 3 Cast Guide: Who’s Who in Westeros and What Happened in Season 2?
“House of the Dragon” returns after a two-year break on Sunday night for Season 3, bringing “Game of Thrones” fans back to the dragon-filled days of Westeros.
After Season 2 built up the Dance of Dragons civil war but stopped short of showing the first major battle, Season 3 will continue the action and kick off with the Battle of the Gullet. In George R. R. Martin’s original novel, “Fire and Blood,” the Battle of the Gullet is one of the deadliest naval battles in Westeros history. It’s the first of many bloody battles between Rhaenyra Targaryen’s (Emma D’Aarcy) black army and the greens, led by King Aegon II Targaryen (Tom Glynn-Carney) and his mother Dowager Queen Alicent Hightower (Olivia Cooke).
Back in Season 2, Aegon was severely burned and crippled at the Battle of Rook’s Rest after his brother Aemond (Ewan Mitchell) turned on him during a high-flying dragon showdown. Aegon plummeted to the ground and was slowly nursed back to health, while his one-eyed brother sat on the Iron Throne in his stead. In the Season 2 finale, Aegon and his advisor Larys Strong (Matthew Needham) flee King’s Landing for his safety. Meanwhile, Alicent held a secret meeting with Rhaenyra that would allow the Targaryen to take King’s Landing in exchange for Alicent’s family to go unharmed.
