Long, long ago, when the two worlds of Day and Night split apart, the Wonderbolts and Shadowbolts did as well. The Wonders belonged to the Day and the Shadows, to the Night. Rumors turned them and their worlds against one another, becoming sworn enemies. The bond that once kept them and their worlds together had been reduced to nothing but bitterness and hatred. To ensure no connections were made, a forest full of danger separated each worlds' territory. The dense hatred grew over time. Then, on one fateful day, everything changed.
Soarin, Prince of the Day and an elite Wonderbolt wonders about the Night World. Rainbow Dash, Princess of the Night and an elite Shadowbolt wonders about the Day World. When they meet in their youth, they develop the most forbidden of friendships, meeting in secret as often as they can throughout the years. One day, it turns into something more.
But on the same day, their secret gets out.
Spurred on by hatred and betrayal, the two worlds prepare for war. Can these two friends prove to their people, enemies, and families that love and harmony is possible? Or will they never get the chance to be together like they want?
Follow them on this journey of love, trust, and betrayal as they teach the world and each other what True Love is - putting aside the biggest differences to accept them for who they really are, and to show that they are willing to do anything to ensure that the other is safe and happy.
EDIT (1/21/18): I hate to disappoint you guys, but I'm officially canceling this story. This version, at least. I jumped into this with no plan and in the process, got myself stuck in a messy web of world-building, details, history, and everything that this AU doesn't quite have set in stone yet. I'm leaving this here for your viewing pleasure, though, and I promise you, whenever it is that I get to rebooting this, it'll be much better; because then, it'll actually make sense.

I loved the "short" description, but the prologue not so much. You're saying there was a night kingdom and day kingdom living together in harmony, but even before the split they were still separate geographically?
Wouldn't it be more logical if they were in the same area and half the people were nocturnal?
And you're saying this split/ war was caused entirely by 2 people, spreading rumors, for no discernible motive; and Luna and Celestia who are both ancient fall for it just like that?

You know, in all honesty, I was kinda waiting for someone to point this out, just to make sure I wasn't the only one who saw my many flaws in this Prologue.
It's been, eh, maybe 10-ish or so months since I wrote this, and I decided to bring this story from my Wattpad to FiMFiction. Back when I first wrote this, I remember having pretty logical reasons as to why I put it like this, but as I kept looking back on it, the whole scenario seemed really unbelievable and my reasons weren't very logical anymore. You make a very valid point - only two people, creating rumors that start a war? Yeah, right, like that would actually happen.
As for the whole situation with the worlds being separate, I guess that I kept in mind that since there were two ruling monarchies, one for each "world" or "kingdom" or whatever you wanna call it, I gave them their own "territory". When I envision the settings in my mind now, I see two palaces, one facing another, and between those two palaces are your standard community - homes, farms, roads, villages, markets, etc. I honestly don't know what I was thinking when I wrote "border separating the world territories" when it's supposed to be a place of peace and harmony. I was, however, planning on making the Night population nocturnal, though that would be specified more in future chapters. Maybe back when I was writing this, I kept in mind that since the Night population would obviously be awake and loud and other stuff while the Day was asleep and would most likely not want to be disturbed, I gave each kingdom their own space so they could continue their activities without disturbing the other. But then again, if it's supposed to b a harmonious society, both kingdoms would stay up later than usually to spend more time with one another. Though I do know that one thing I won't change and think that I should mention is that sunrise and sunset were very popular times for big gatherings, celebrations, or just typical meet ups. Yeah, I have no idea what I was thinking about this.
And in the author's note, I said that I made Celestia and Luna friends instead of sisters, and I decided stick with the traditional cycle in a monarchy and have the crowns passed down to the next heirs to the thrones, hence why I didn't make the two immortal. I think that's the one of the very few things I won't change, because I feel like since it would be history, it can be something to think about and debate, and other details I have in mind can be built off of it.
I guess it's sort of the reason why I haven't worked on this story in so long. I keep on thinking about the unrealistic properties of it and it bothered me for a bit, so I spent a lot more time thinking about trying to fix it rather than the actual progress of the story itself. All I knew while I was planning out the prologue was that it would explain a conflict (I'm not sure what yet) that lead to a war, a split that lasted for centuries, and introduce the start of a forbidden friendship between a Day prince and a Night princess.
I'm sorry that this prologue wasn't very explanatory and specific like it should've been, nor is it what you may have expected. I'll fix this as soon as I can. 
are you going to conitinue this story because I really want to know what will happen next,please
Please continue!
Please update please please please this is so good
