Season 1 of House of the Dragon set the stage for the civil war known as the Dance of the Dragons between rival Targaryen factions. The two sides are often referred to as The Greens and The Blacks, due to Alicent Hightower's dramatic entrance at Rhaenyra's pre-wedding feast in a green dress. Some interpreted this as a call to war, seeing as House Hightower calls its banners with a green flame, and in the books, Rhaenyra wore a black dress.
