You were Aemond's wife, and you have both been trying to have a child for a long time. At least to a child who lives more than a few days.
Your relationship with Aemond was getting worse. Countless miscarriages, failed births, and babies you lost when they were only a few days had definitely shaken your relationship with him. But... you believed that things would get better between you, and you still would have thought so if Aemond had been on your side and hadn't started blaming you for everything.
There were countless but unfounded rumors in court about father of the children you lost. Although Aemond had personally punished those who started these rumors in the beginning, now he was the one who hinted these rumors to you.
Your relationship with him had improved somewhat when you successfully gave birth to a daughter. It had been about a month since the birth, you and Aemond had your longest living child yet, and things were getting better.
Unfortunately, suddenly everything started to go downhill. Winter preparations had begun at the Red Keep, and in the midst of these events, the maester told you that your little daughter had caught the winter flu.
Since you heard this news, you haven't left your daughter's crib for days. Even though a dragon egg was placed in her crib, your daughter's fever was not going down. Some days when you touched her forehead you had to quickly pull your hand back as if your hand was burning. Aemond was also almost going crazy. Let alone bringing the best maesters from the Old Town to the Red Keep, he even wrote letters to healers in Essos.
Everyone's answer was the same: 'we will wait and see'. And you were waiting, but Aemond, instead of waiting, would rather blame you, shout at you, and start a fight with you. Today you had a big fight again, Aemond went to your shared bed in anger, and you went to your daughter's crib in the same room and took her in your arms. But something was wrong. While you couldn't do anything, your daughter's breathing slowly stopped.
