After devastatingly losing her battle against Starlight Glimmer in the Season 5 Finale, Princess Twilight Sparkle is shunned from true reality and must learn to live in the ways of this alternate dimension. In that dimension, she finds a banged-up Nightmare Moon huddling in some bushes, bleeding badly. Twilight has a great idea, and so she takes in Nightmare Moon as both a "daughter" and a pupil, raising her to be the best she can, making sure she won't try taking over the world (even though she was Nightmare Moon). However, both ponies must face serious challenges. Will they make it? Will Twilight be killed somehow by Nightmare, or will Nightmare's reign last forever once she finally achieves it?

Past. Sins.

8201901 Pretty sure Past Sins didn't have the Starlight angle in it or Twilight being a little messed up in the head,
8202079
Haha thank you so so much!!
8202018
Thank youuuu!! So glad you like it!
8202181
Yes, yes
I am working on it right now, the next chapter is going to be pretty interesting
8202174
Is that a good or a bad thing? ^^
Nightmare Moon is a filly in this story, right?
8202343
Yes, yes indeed
But as time passes she will grow into a teen, and maybe, just maybe, a full-grown mare
Won't Nightmare Moon take like... forever to physically grow up?
8202379
Yes, it would take a while, and that will be a long time yet to come
8202384 Wow, you replied Immediately, thanks! Oh, also, amazing story so far
8202391
It's my pleasure
Also I replied quickly because I am actually working on the third chapter right now and get the notification when you comment ^^
And thank you!!
8202307 please can Discord be involved i just love him
8202491
Oh, er. . .I worked very hard on a full-on storyline (made a google slides and everything) which is something I don't usually do and I am very proud of this original idea
Perhaps you could note me when I finish this story about some sort of Discord story you want? If it helps, I can make a Fluttercord one

s-media-cache-ak0.pinimg.com/236x/88/c7/5c/88c75c880690f590537c7e3dc15cbe37.jpg this what someone did when tacked to do king sombra as a human
8202210 Its like past sins in that in both stories, twilight cares for a filly nightmare moon.
Okay, I feel I need to put my two cents into this...
First off, it seemed from the start that this was a ripoff of Past Sins by Pen Stroke. While this takes elements from it (like filly Nightmare Moon being adopted by Twilight), this seems definitely different, so I guess I'll let it slide, at least for now. In any case, you ought to read Past Sins so you don't accidentally steal anything, if you haven't read it already.
This seems a bit rushed and light on details, and I noticed a few spelling and grammatical errors, but since pretty much nobody likes "that guy", I'm not going to be that guy, and I'd suggest looking through it a bit more (though if you want me to point out the errors, I will oblige).
Now what did I like?
Well, the whole concept of Twilight having lost to Starlight and seeming a bit crazy as a result is interesting and can make for good storytelling if done right. I liked what I saw of it so far and I'm certainly enjoying it, at least to some degree.
I can't upvote this in good conscience, nor can I downvote it. All I can do is say my piece and track the story. Good luck.
Please do continue...
too rushed, and seriously I can't see Starlight more powerful then Twilight. and where's spike.
8203158
Don't forget Twilight had to recast that time spell (which seems to be really draining) each time she goes back while Starlight is automatically brought back because of how she altered it. Meaning Starlight gets to rest each time but Twilight has to deal with the AUs and then recast the spell and go straight into combat.
8202891
Oh, trust me, I will!
8203158
Well then we have conflicting ideas
Also Spike will not be in this story, I forgot about him...
8202686
I keep on getting that
I have added past sins to my read it laters but I struggle with reading on a computer or any other piece of technoligy
I will look into the story (because sometimes this happens to me, where I have a much similar idea) after I write this. Why? Because I don't want to be inspired and also because then I have to say I have read past sins before, which makes me seem even more like a phony
I am so sorry that I have made this very similar to that of an already made story, but I am pretty sure that once we hit the climaz things will change
8202613
Well, she was looking forward to helping a pony she knew in her other world become an even better pony with the right treatmeant
Also Twilight has been stupid like this before, in the sense that she has accepted Starlight's apology after she tried "breaking the world apart" yet won't accept Trixie's *before the season 6 finale* when all Trixie did was put a small town in vein, when it wasn't even her own personality, since she was wearing the Alicorn Amulet. Trixie was a fraud, Starlight tried destroying the world because she couldn't see the outcome of her foolish actions. I am not putting hate towards anypony, Starlight Trixie Twilight or you, I am just stating this
8202660
Thank you for trying to help, but I know myself and if I read past sins there is a chance of me being inspired, thus leading me into making this story evan closer with out realizing it
8202528
Cool
this is a very strong start. keep it up!
8239877
Aaahhh thank youuuuu!!
8240943

Good so far. Has potential. Tracking.

8322043
Aw! Thank you ^^
8322884
Sure is!
In truth, he's actually not her father!! He just forced her to bow down to him and such, now everyone thinks he's her father!
I really liked your comment
Hearing stuff like that always makes my day! 
8322952
I'm glad to hear that!
I hate that stallion already.
