Given the timeliness of this post
In the episode "Lord Snow" from the hit HBO tv series, Game of Thrones, Daenerys Targaryen corrects someone who calls her a queen, saying:
Not a Queen, a Khaleesi
I have a crown
She wears a crown
Yet I'm not a queen
She doesn't call herself 'queen', rather a 'Khaleesi', which is the Dothraki equivalent.
I have a lot of children
She considers her dragons to be her children, hence the style "Mother of Dragons". Additionally, she is referred to as "Mhysa" which in Valyrian literally means "Mother", having freed many slaves.
Yet I don't have a husband
Her late husband - Khal Drogo - well, he dead man.
Who am I?
