The princess has gone quiet. Ever since the nations began uniting under one flag, the princess has refused to see anypony, and nopony, not even Celestia's sister has seen heads or tails of the sun goddess.
She only wants to see her student.
Twilight ventures to the castle to see what exactly is the problem.
This whole thing was inspired by one little part in the cover picture. I don't know how many people agree with me, but she (Nightmare/Celestia) seems more concerned than anything else.
EDIT: I was planning on making this a one shot, but fate insists that I change that. No longer will this be a one shot, but a two-parter, I think. 5 comments. Holy shiznits, I must have done something right.
Chapters (3)
Not bad, but I don't think a creature of such indomitable willpower like Celestia could give in to such corruption. Possible, but far from likely. Just because it happened to Luna doesn't mean it'll happen to Celestia and everypony else.
Hey, I think it's a good idea.
That and I really like fics where main characters could possibly become corrupt.
Corrupt Twilight, please. dl.dropbox.com/u/31471793/FiMFiction/discord.png
However, I though that your writing style was good, and I like the idea of Nightmare not completely corrupting a pony fully.

Well, that depends on what Celestia did it for. She did say that she united all the races and such under one banner peacefully, so that means that there could have been a cold war of sorts, and it gave her a way to make sure that everyone lived safely.
Another chapter please
Hmm... It ends with so many questions still unanswered and without real closure between Twilight and Nightmare/Celestia. But I kinda like it that way.
I feel like there shpuld be another chapter or another story based after this one-shot. But I still found this a pretty alright story.
That was a pretty major cliffhanger.
But it was good nonetheless.
Yeah, it's not really complete as it currently stands. I'd like to see more.
It would be interesting to break some of the Nightmare Celestia tropes and have everything she's saying here be true, too. Rather than "giving in to corruption" Celestia might well have tamed the beast. I would like to see Luna's reaction to all this, too.
1046002 Chill. It's alright. I'm working on it.
yes this really should be continued if not turnt into a series if your up it......it seems if the nightmare wasn't really tamed then its presence within celestia probably only corrupted her form and not her mind. Although there is leeway on how her perspectives may differ yet retaining her original feelings and intentions......atleast concerning twilight......although at time if she is just nightmare then her connection with twilight so ingrained that she literally can't bring harm to her "faithful student"(srry luna)......but this is just plot speculation......soooo meh...
1046083 Thank you for your speculation, but I have already put some thought into this.
1045993 Truly, it is a terrible cliffhanger, isn't it?
1045813 Continuing. Sorry to disappoint.
Wow interesting idea indeed. I think it's way to short though, I mean this piece is just drowning in potential!
GAH TOO MANY UNANSWERED QUESTIONS! PLEASE FOR THE LOVE OF ALL THINGS HOLY, CONTINUE!
Yes, the world needs more Solar Flare(Evil Celestia) stories, even if the nightmare is satisfied with power for now, that cant last to long since there is always more power to grab.
Will be interesting if we see how the world was united, maybe something like it being done through threats of total annihilation (without Celestia herself being aware and the nightmare changing her perception).
Whatever you do with this it will be interesting.
Yeah, I'd really like to see more chapters of this.
what why how is but i what in huh who what why how she her what?
WHY IS IT SO SHORT!
1067342 dude, chill. I'm a work on it.
Why last when it can go on and on and on and on for all eternity!!!
gah i don't care that its short, i like how you did the concept of this. My only issue is that the whole story is cut short......but your the author end it as quick as you want......
1067365 Now you've done it!!!
1067390 I appreciate you not blatantly demanding. beside the point, it wouldn't have helped you anyway!
1067408
........................
1067360
I didnt mean it that way
*beats you on the head with a book anyway*
1076949 ouch! how dare you!?!
1078467
That's what you get for that cliffhanger. Perhaps if I beat you on the head enough, you will learn not to end chapters with cliffhangers anymore.
1079830 you're so mean...
1080005
Perhaps I will go a tad out of character though, and not hit you on the head with a book again if you update soon. 
Glad you noticed!
this was a really good one! albeit short. I mean I think you could have delved deeper into it and all so
1085688 Yeah, well, if I dive too deep into a story, it takes forever...
1085683
Have to agree with that one.
But pity the nightmare for being so misguided believing power means life/living.
1086210 well (start thinking) I have a story idea involving the nightmare and my main oc
1086210 Really, the idea was for you to figure out what it meant by life, whether that meant power is life, or power to preserve life.
1086402
You win some you loose some, but why not from the start explain its to preserve life, why make a reputation for yourself that you drive your hosts crazy. I dont think it picked the name "nightmare" for itself
Of course thats what i think and isnt "canon" for this story. Im just taking (what i hope is) a objective view on all shown and presented here, im happy its a happy ending, im a sucker for them too. But generally if your intentions are pure you wouldn't need to take a shady route to get them.
Generally, you can easily explain all by expanding on the story.
1086492 Fine, fine. you may all hit me with books now, I'm doing it again.
1086522
It actually worked and your going to write MOAR?
1086527 No, I don't think so. started writing, didn't work, deleted chapter. I change my mind so much sometimes...
Well, since your ending was satisfactory for me, I shall not hit you on the head with a book again.
But Just this once. 
Allow us to get this straight.
Nightmare is in fact a symbiotic entity which is not inherently evil and only desires power.
And Celestia willingly becomes Nightmare's host, then peacefully unites the nations of the world in hopes of satisfying Nighmare's lust for power, which works.
Now she looks badass.
Seems legit.

Hm... interesting. There is a few problems with this however nothing that breaks it. I think mabye you should rewrite it. but thats mainly my opinion. you can leave it be if you want.
1168364 Really, the whole thing is over and done with. And typically if I jump right to rewriting a story, I usually end up making it worse. So, if I did that, I may unintentionally take out something you people enjoyed.
1168934 Alright then.
To be honest I'm still not too sure about this story, the whole thing about Celestia willingly becoming a host for the thing that caused Luna's Fall just bugs me (mostly for two reasons, both are no fault of your own, 1) Too many Daymare Sun fics out their, 2) My own headcanon). Still this is a good story, short but still good.

1188020 Don't judge me! This was an entire story derived from a part of a picture!
(Personally, I prefer the name "Solar Flare", it just rolls off the tongue better) If you were wondering, I actually violated my own headcannon to do this. However, I did not list this as "alternate universe", because we never figure out what the nightmare really is, be it a part of Luna's mind, A symbiotic creature, Or just Luna with a different name.
Now, when you try to consider Celestia's motives, I think it makes far more sense than you think it does. When it took over Luna, it seemed to work with her feelings, using them as a way to gain power, which in that case, power came from the (attempted) overthrowing of Celestia. Celestia, being far more experienced and having lived longer than Luna (in hypothesis), probably found no pleasure in the less fortunate outside of her country having less rights under their perspective rulers. The nightmare would have stepped in, eagerly taking on an opportunity for easy access to power. Why would it become docile? I don't know, I suppose it was something along the lines of "Yes! I rule the world! ...now what?"
I have let you in on the mind of the man who crafted this story. Don't expect it to happen often.
1188118
I mean no disrespect and I'm not judging you, and to be honest I did look at the picture and I did see what you saw. No hint of evil, but the concern and hint of curiosity.
Your explanations do make sense, and I can see that was where you were going with the story.
Celestia's Paladin
It's short
Make more because I like this story!!!!!!!
I hate you and your short stories!!!
Sry. I really like it though. Nice plot. I think either you should continue or someone should pick up where you left off.
1195840 Please, bring your eyes upon the bottom section of the chapter list. I see the words "complete". With such words, you should assume I will not be making any more. What could I possibly do with it? The whole story came from a single section of a picture. I have no intention of making this a big project, as it is complete. Now, if I were to divert your attention to what actually is my big project, please head over here, and take some time out of your life to read this. I assure you, it is not short. and please, comment on that story, and show it to others.
Recently i have seen a few stories that begin with the idea that NMM only became Nightmare because she was corrupted by Luna's anger/hate/jealousy/etc ... That Night Mare was originally something far different than the monster that she became after "joining" with Luna ...
heck ... this story may have been the inspiration for them ....
good job!
Shown - Past form of show in some obscure form
Shone - Past tense of shine
That is all~
I like to see her wanting power as a way to live. She has no body of her own, and needs a powerful one to live.
