Mysaria was taken as a lover by Prince Daemon Targaryen in King's Landing, and she quickly became his favorite. Around 105 AC, Mysaria became pregnant with Daemon's child while living at Dragonstone. Daemon gave her a dragon egg for the child, which angered King Viserys I Targaryen. The king ordered Daemon to return the egg and send Mysaria back to Lys. On her return to Lys, she lost the child during a storm on the narrow sea.
During the Dance of the Dragons, Mysaria was involved in the assassination of Prince Jaehaerys, a son of King Aegon II Targaryen, when Daemon desired revenge for the death of his stepson, Prince Lucerys Velaryon. She was Daemon's go-between, a "pale stranger" whom he trusted, who hired the assassins, Blood and Cheese.
