UPDATE:
So it's been a year… close. And I'm entirely grateful for the reviews, views and love and support as much as I am sorry that I had to leave this story behind. I had some personal issues and I was side tracked to the point where by the time they were over, the story had been long lost. My heart was no longer in it and neither was my focus. I apologise and am sorry to announce that I will not be completing the story. However I do owe you answers to your questions. So, here we go;
Why did you kill Robb?
My idea to kill Robb was to stay true to Daenerys story; with Robb it would've been hard to claim Daenerys strength and say 'she did it for herself'. Plus, I found it interesting to see how she would be without Robb and surrounding by second-guessers and Anti-Targaryen supporters. I wanted Daenerys to be at her full strength so it was vital to have Robb die, also to keep the Boltons and Freys and Tyrells a huge part of the story to fuel her determination.
What happened to Catelyn and Arya?
Catelyn perished saving her daughter as they were attack, Arya, escaping with Hot Pie and Gendry. Arya made her way to the ruins of Winterfell to head to the Wall for Jon. From thereon nothing is heard from her.
What happened to Sansa?
Sansa remained at Kings Landing, her story being the same as the books/series. However, her ending is alternate and she is saved by Daenerys, who wins Kings Landing. She is later promised to marry Daenerys firstborn setting her to become Queen, she is also given Winterfell and named Protector and Mother of the North.
Was it Ser Barristan that saved her?
Yes, it was. After plenty of misleadings to her whereabouts; he arrived in time to save her.
I hope that was all answered for you, I have plans to return to the site but am not sure what to write, it would be perfect if you could tell me what you would like to see me write next; what TV Show/Movie/Book and what content.
