Last we looked in, at the end of season 1, King Viserys I Targaryen was dead. His son, Aemond Targaryen, riding the dragon Vhagar, had just killed his nephew Lucerys Velaryon and his dragon, Arrax, in an epic mid-air battle. Clearly, there are no take-backsies at this point. This means war.

So before you jump into season 2, here’s a list of the House of the Dragon season 2 main cast and the characters they play.
