This story is a sequel to A Sunlit Night
Young Sunset Shimmer has just learned of Celestia's sister after being accepted as her personal understudy for her great magical prowess. However, has Sunset already met the Princess of the Night without knowing it or is it somepony else who calls Celestia her "dear sister?"
It is not necessary to read A Sunlit Night before this one as this is its prequel, but you will most likely find it far more enjoyable. 
Takes place before A Sunlit Night and focuses around the flashback of when Sunset was still rather young and had received her cutie mark. I know some of you wanted to know more about how Sunset knew of Luna even though she would still be banished to the moon during this time period. It will cover Sunset's life from when she was in grade school up to when she becomes Celestia's pupil.
FYI: The artwork belongs to me so don't worry about the source.
I'm sorry that I hadn't seen this until now, but I'm still not able to start reading it.
I just thought that I would let you know that this story has been seen, and will be read in the near future.

It's quite alright and, actually, I suggest that you be patient with this one as I hope others are as well.
As some of you may or may not already know, Fallout 4 has recently been released and I have unfortunately, despite my better judgment and own willpower, acquired this soul and time consuming piece of hardware. Updates will be very far apart, slow, and most of all very small. I am very upset that I won't be able to get this story out at a more desirable pace, but this fic is going to be another long one.
Actually, if my guesswork is anywhere near as accurate as I think it is, then this one is going to be a bit of a doozie, according to my standards of writing. It may in fact be even longer that its predecessor, and I am putting money on it will in fact be. So while that may be something to look forward to, my feelings on the subject are a little more on the fence since I have to do all the work.
As of right now, I am also trying to catch up on several things in my personal life with holidays, cleaning, art, family, as well as numerous online things as well.
I've been sort of working myself into a small pit of stress and anxiety which I juggle around every so often during my average week. Not to mention the possibility of getting a new job soon to add in at a later date.
However, whenever I get any inspiration to write, I will lock myself in my room and get as much out of me as I can. Promise.
I just ask that all of you who support me and my small writings will continue to do so even if I'm dragging a bunch of you along without any sort of reward for a little while here. It really means so much to me whenever I see some of the comments you all have written. I may not be a very famous fiction writer, or for that matter a very good one sometimes, but I am absolutely overjoyed when I see the few I get. It fills me with determination.
I am such filthy trash but I have no regrets.
Well that was interesting at the same time reading the warning made me think " unbearably slow pace huh? You couldn't be more right about that, a 5 years of slow paceš¤£"
