Fire & Blood Vol. 1 | Jaehaerys and Alysanne - Their Triumphs and Tragedies (Chapter 10)

With no new news of Aerea, Rhaena, or the dragon eggs, Jaehaerys dedicated himself to organizing and reforming all of the realm’s laws. He set off on another journey across the realm while Alysanne went to Dragonstone and gave birth to a boy, Aemon. In King’s Landing, construction on the gigantic dragonpit finally finished, and the monarchy held a great tournament there.

Elissa Farman changed her name to Alys Westhill and took her boat around Westeros to Oldtown to find a crew to take her where only few had gone before, into the mythical sunset land she had dreamt of sailing since a girl. The Targaryen's heard about her intent, but by the time they arrived to capture her, she had sailed away and they could not find her.

Aerea returned to King's Landing on the thirteenth day of the fourth moon of 56 AC, with a severely-ill Aerea clinging to the dragon's back. She was almost unrecognizable; she was stick thin, and whatever clothes she still wore were nothing more than tatters. Her hair was matted and a tangled mess, and her eyes were bloody. After speaking "I never", Aerea collapsed.

Following Aerea's death Balerion became the first dragon to reside in the Dragonpit, guarded by the new Dragonkeepers. Barth began studies that caused him to write "Dragons, Wyrms, and Wyverns." He likely discussed the princess's death with King Jaehaerys, who issued an edict forbidding any ship suspected of having visited the Valyrian islands or sailed the Smoking Sea from landing at any port or harbor in the realm. Any Westerosi who visited Valyria would be executed.
