The world has died and is nothing more than ash and dust. The land of Equestria is a far off memory along with those who once inhabited it. Wandering the empty land is the sole survivor of the cataclysm that brought about the death of the world. Yet this sole survivor is also the harbinger of the world's death. In the final moments of the last living thing in the world, the story of how the world died is told. One of many ways the story could be told and one of many ways it could end. This is the day the sun set for the last time.

6779435 Thanks.
OMG...this is some deep stuff.
Oil just pretend this is the real ending for that dusty world twilight found.
Its the best I've got.
Awesome!
can i cry now?
im guessing this is told by celestia
Well done! Very moving, and though I knew who the speaker was, it had be invested in the tale from top to bottom.
6779781 Thank you very much.
6780115 Thanks.
6780558 Yes, you may cry.
And It's actually Gummy telling the story. 
6780941 Thank you.
ok i'm gonna start crying like now and i would have never guessed it was gummy
Deep stuff. I guess the plundervines incident never occurred, perhaps because Celestia killed Discord or seared the Everfree Forest to the ground in one of her adventures.
6785634 Thank you. The vines are the after effects of Discord's magic after he dies. They are the reason she burns the forest.
Oh my...
This was pretty freaking deep...
6786523 Thanks. Glad you liked it.
7526831 I would prefer you not promote other stories in the comment section of my stories. Even if you are just suggesting similar kinds of stories. I don't like to do this but I will be deleting your comment.

Can you point me in his direction? Or at least hint on what it is he commented? PM me.
Im always curious what people's replies are to my comments.
Best depiction of what happened in the apocalypse timeline.
Also roughly my assumption, as in headcanon. Celestia nukes the world, trying to save the day.
8065274 Well, thank you. And that does sound like another way it could have happened.

Now imagine it this way...
As Celestia calls down a piece of the sun on Tirek, the quiet piano piece from Mass Effect 3's ending plays, and we get short flashbacks of the individuals who were important in her life, who were lost to the evils she had to fight. Luna, pre-corruption, then Cadence, after her ascension, both turn and face her to smile, then Shining Armor and the royal guard, saluting, before switching back to the present, focusing on Tirek, who is vaporised by the explosion of nuclear energy, and then a wider angle as Celestia teleports away and the explosion silently engulfs the area, then the region, levelling everything in the way.
I just activated all of your feels. You're welcome.
This was amazing; I feel like I actually finally know where that timeline came from now.
Fantastic!
