OK so there are several things to note as you continue:

Most of this story is set mainly during World War Two. I did some light research (IE I have a history degree, have read alot of WW2 setting novels over the years and can google) so while I tried to keep things within the realm of historical possibility I am by no means claiming any type of complete historical accuracy. There are certain events, regulations and information that I did draw on but there are things I may have fudged timelines on in order for it to fit to my story (IE something that was not available until 1942 might show up in 1940). With that said if there is anything that is just so wildly off that it destroys the story for you please let me know so I can make an attempt to correct it. Also while I am writing British characters I am not British, so I'll just apologize now for anything that is wrong with regards to that.

I have set most of the story on Oakenshield Island. This is a real island in the GOT world, however besides the name I did not really use anything else about the island. For this story the island is located in the English Channel and would be similar to Jersey or Guernsey. I choose to use an imaginary island though in order to not be tied completely to historical facts and events.

Lastly, while this is a Jonsa story, their part of the story picks up much later in the story, and while I love that part and think its worth the wait, this story is much more than just them. I tried to craft a story that is about all of the characters relationships to each other and what they go through. So the initial act of the story belongs mainly to Sansa and Arya, and really overall this is just as much their story as Sansa and Jon's.

So with all that said I hope you enjoy and thanks for reading!
