The Red Keep was taken by the Blacks days after the coronation which resulted in end of the conflict without much bloodshed. After weeks of negotiations, it was decided that the will of Viserys I shall be accepted by the High Lords and the pretenders to the throne. Otto Hightower and his dynasty was banished from the realm except for Alicent Hightower. Thus, the Dance of Dragons has concluded without even starting. Queen Alicent Hightower was given two options to become a silent sister or a septa and she chose the former. Aegon II kept his claim and was named the Lord of Oldtown and the Lord of Hightower for the blood of Hightowers runs in his veins. Aemond fled to the Stormlands but after hearing the news that Boros Baratheon was sent to the Wall just like most of the Greens, he left Westeros on his dragon and now lives in Essos brooding and planning his revenge. During coronation Queen Rhaenyra managed to make peace with her brother and sister while also forgiving Alicent's betrayal. Daeron Targaryen was named the Lord Commander of the Queensguard where he proved once more that dragons are nobler than common knights of Westeros.
