Thinking about Ygraine (idk how u spell her name so im gonna go with this whatevs) and how she told Arthur "Now that I see you I would have given my life willingly."
Thinking about how she must have felt terrified, betrayed, used, desperate- if not only in her last moments but once she understood she would die.
Thinking about how she and Uther vowed never to change the other in any way, to love the other as they loved themselves. How she realized, once she found out his treachery, that he had broken that vow. Nimueh was his sorceress, and Ygraine was his queen. Not a friend nor a lover nor an equal partner.
Thinking about Ygraine receiving disjointed visions of the future- whispers of prophecies of the once and future king. Thinking about Ygraine losing her grip on the mortal plane as her child grows stronger.
She breaks. She cries. She begs. She doesn't want to die. She receives no answer but whispers about fate from the dark. She rages. Disowns Uther, disowns her crown, her throne. The entire kingdom. If she is to be cast aside by her friend and king then she will spare no more love for them.
She is confined to her chambers. Physicians and healers (not Nimueh-never Nimueh, she knows there is nothing to be done, and she prays), trail in and out, their efforts ineffective. Her brothers are allowed to visit her after months of beseeching the possessive king. But they cannot reach her, not completely. She is far away now. Sometimes her eyes change color.
She shouts of death, and dread, and magic. She doesn't know what it means, nor does anyone else. She is so so afraid when death finally comes. Her last thought is that her child would grow up without her, and wasn't that fitting, she thinks even as her heart breaks, this was never supposed to be her choice.
