In the second season of 'House of the Dragon', we can see team Greens (Aegon) and the Blacks (Rhaenyra) going on a war.
While Rhaenyra was trying to avoid war, she will surely take revenge for her son’s death. Another thing that we can expect is a time jump. However, showrunner Ryan Condal has stated that there won’t be any in the coming seasons.
We can expect more dragon fights and chase scenes in second season since both sides own several dragons.
Season two will also focus on Winterfell and the Starks, which were briefly mentioned in the first season.
The second season will primarily focus on the Targaryen civil war that led to the eventual decline and disappearance of dragons.
