House of the Dragon is turning up the heat. The teaser for the Game of Thrones prequel series sees dragons soar above the shores of Westeros, where soldiers fight on both boats and land in the war named Dance of the Dragons. "The road ahead is uncertain," King Targaryen (Paddy Considine) says, "but the end is clear." The king is confident that "whomever may dare to challenge us" will be defeated, noting that the Targaryen's army is bigger and their dragons are stronger. Previous previews of the HBO series teased the power struggle at the centre of the show, which sees two of King Viserys' children fighting over who will sit on the Iron Throne. While King’s daughter Rhaenyra (Milly Alcock plays teen version, while Emma D'Arcy plays the character as an adult) is initially named the heir, the king later welcomes a son, Aegon (Tom Carney), who is conceived after Rhaenyra is declared the heir. The series will depict how the Dance of the Dragons plays out, and will offer more insight into the demise of the House Targaryen, which was briefly touched upon in Games of Thrones.
