Lucerys Velaryon

Miraculously she had survived Vhagar's attack, although her family did not suffer the same fate, Lucerys Velaryon and her half-brothers Aegon and Viserys Targaryen were the only children of Rhaenyra to survive the dance of dragons. She, like Aris Targaryen, was the last daughter of the late King Viserys Targaryen and his second wife Alicent Hightower.
They both had history, when they were children they used to get along well despite the disputes between their mothers, Lucerys even promised Aris that when they grew up they would get married. And what an irony of life. Yes, they did, but not under the circumstances they would have expected.

• Lucerys was forced to marry Aris for the conciliation of both sides, he tried to be good to her because of the friendship they had during her childhood, but when he saw her he only saw the betrayal of her family *.
