In the beginning of Celestia and Luna's reign over Equestria, it was decided that four alicorns should be created for the second most powerful elemental force other than Night and Day, the seasons. Four "Keepers" were created for each season, and were tasked to control the weather during their season and provide smooth transitions from one season to another. Luna created the Keepers of Winter and Autumn, Snowhoof and Amberleaf; while Celestia created the Keepers of Summer and Spring, Brightmane and Lilyheart.
Now we draw to the present. Luna has returned from banishment, Snowhoof also had been banished and he is returning
as well. In Luna's absence, international relationships had degraded and the whispers of world war pierced the uneasy tranquility. With Luna back, world leaders fear more treachery from Luna, and a harsh winter from Snowhoof as vengeance for his brutal incarceration. War breaks out as leaders fear food shortages, and adverse climate changes. Starlight Mirror, Luna's champion and general, must restore peace before the world is engulfed in war.
Contains: A few instances of foul language, combat violence, and suggestive material
If you guys have any suggestions or anything, please say something. No one has said anything so far, and I'm wondering...
Make Maelstrom all powerful overlord god king alicorn, that is my suggestion.
4296621 I agree with LordRaimondo. Maelstrom should be called Malestrom for his manliness. They say alicorns are like gods in Equestria and they also say manliness is next to godliness, so sexy manly Maelstrom should be an alicorngodkingpharoahbigwhigmeisteremperor.
Luna doesn´t give a fuck about gryphons, does she?
4304565 What do you mean?

Well, the scene doesn´t clarify if Luna is expressing indifference to the griphons tribulations plus what
Snowhoof´s winter will cause to their kingdom, or spite to the captured invasor who spilled her subjects´ blood, or both.

Someone very near and dear to her, Snowhoof, said that he no longer wants her in his life. She thinks herself as his mother, and imagine if your son said something like that to you. I'd be heartbroken. Snowhoof hates her now, and she feels like she has lost him forever

And how does it relate to the prisoner´s plight? While Luna surely doesn´t like the suggestion of putting his son in chains again, she should at least show some empathy for the griphon´s motivation, who is not begging for his life but for the lifes of his entire people.

Snowhoof has promised mild winters. That vow, Luna believes will diffuse the situation between the gryphons and dragons. And the gryphon's won't lose their territory either or any population.
They gryphon captain, justified or not, killed many of Luna's soldiers and almost killed Starlight. Snowhoof was serving justice, even though it was very cold hearted. Because that's just who Snowhoof is.
4296709 i agree with you all an all but starlight a real nigga
4313017 Seems like I started a craze.
4313038 but did you not hear what i just said. Starlight the man with the plan
4313047 Starlight is nothing compared to Maelstrom. Maelstrom is a boss.
He is easily the best character in this fanfic. Maelstrom for best pony.

I was looking at your story and noticed that it was complete. This story looks very interesting, but I also see that it doesn't have a lot of views. Have you considered posting your story in some other groups? It could really help give it some more attention.
Never expected this ending! SO many upvotes!
I think I like where your story is going already; I enjoy how you tell of the seasons. Very creative and nicely worded.
Seriously! Such a great ending!

Thanks! I think it turned out really well for my first MLP fanfic
Promising start, however I must ask: Why are the first five paragraphs done in the first person and the following done in the third? Maybe it's just me, but, unless it's describe that is what he is thinking at the time, it might come off as a tad confusing.

Those are his thoughts. He gives a little speech introducing himself, and I switch into third person. It will remain third person for the rest of the story.
Okay I have read this thing up to Chapter 15 and I feel I can give it a fair critique. Lucaro your story needs only one thing: proper build up for the drama. Case in point: when Brightmane surrendered himself to Cadence in Chapter 11, you showed it happening in the next chapter. What would have been better, in my opinion, is hearing the story told as though it were real-time. Also, you could spare some time to go more into detail on some places and the inner thoughts of ponies on certain matters. Otherwise your story telling style is fine.
Not to mention, that Celestia had blamed him for corrupting Luna, which is probably why she had him tortured in the first place! 
Then upon his release (after an attack mind you, which was meant to kill or imprison him!), he found out that the ponies that were the closest he had to loved ones had betrayed him to a life of loneliness and pain! And, in the chapter in question, the races called for his torture, which is what caused this in the first place! I mean had any one of them even considered, even for a moment, how he must be feeling! 
Did any of them have the common decency to feel any sympathy for the one pony in the world who needed it the most! I mean in the course of a single day, his entire world changed due to the actions of one pony who failed to keep her emotions in check! I mean if it weren't for all the pain he were causing, I'd be rooting for this guy!
Now for a personal moment (you have managed to move me emotionally and that is no small feat! If I could I'd shake your hand or brohoof or something! *Ahem* Moving along.) While reading this story, when I reached the chapter named 'Rage Against Winter' I could not help but feel a small amount of righteous indignation on behalf of Snowhoof! How do I justify this? Well, consider that Snowhoof has not only spent the last 1000 years imprisoned for a deed which he did not do, he also got tortured for it!
And to top it off! the mare that he willingly went through all this for, didn't love him back.
He got tortured everyday for one. Thousand. Years! And she didn't have the decency to see him upon his release, even to say that she didn't feel about him that he felt about her! 
Exactly what the hell was she doing that was so damned important that DAY! Lastly, for being the one to start all this in the first place, I hope that Brightmane bastard dies an agonizing death!
Also, why can't Luna or Celestia control their respective alicorns, like when when Celestia found out that Brightmane was in charge of the attack on Avendale, why didn't she shut him down?!
Don't mean it to sound like a rant, but I had to get that off my chest. Really love the story will finish it today.
P.S. Sorry it took so long to get back here. I got caught up in a contest-which I didn't win- but I just finished reading the other entries. (For the record, the winner they selected, totally deserved it.
Might want to work on the ending too. (Build it up a bit more. Also suggest watching Code: Geass for reference material)
Great story, you had me in tears at the end.
The build up towards the ending does need a little work
but otherwise great all around. May I ask for a small sequel to wrap up Snowhoof's return?
