House of the Dragon is mostly about the children of King Viserys I Targaryen. Viserys wants a male heir, but he eventually decides to name his beloved daughter Rhaenyra. When he remarries and has a son, the kingdom begins its long trudge towards civil war. Rhaenyra and Aegon II are the ones to watch during the Dance of the Dragons, but Viserys has a few additional children. His youngest, Daeron Targaryen, only seems to exist in the script. Where has he been and will he ever come back?
