The Weaver of Time

You all at least know that princess Celestia raises the sun and the moon
Now, we are talking of an alicorn who controls the passage of time named princess Tempora

The winter season comes to land and then the spirit of disharmony returns to evil roots of his past
The massive vortex brought the six of them to Ponyville where everything was twisted and was full of contrasts
The heat and cold, two seasons mixed together in one place
The wanderers can't solve this puzzle of time and space
There was no time before the golden sands of storm approached and it has put those little ponies under threat
Protected by the magic shield and slowly going further suddenly they saw a blurred silhouette

Rusted armor, hourglass on her chest, body is mutilated
Standing in the eye of the storm of time she probably created
Her fur is covered with cracks and her mane is glowing with light blue stripes
We thought there are no more alicorns, but the truth breaks our stereotypes

"No
Stop coming back

You see what you've done
The time is collapsing on us

Now our home was destroyed
But we must stay strong and keep the things under focus

We've always acted alone

We've always been alone
This is the problem you've created -
Descending of our world
And now we need to keep the present, future and past separated"

Ah, there
The tale of the Weaver of Time - Princess Tempora
She continually uses her magic so that the time would follow a succession and not get tangled in a knot of possible past, present and future events

Without the elements of harmony they can't prevent the aftermath and then Nightmare Moon is back
But she was not the only one who has returned from deeper past - there is Queen Chrysalis with changelings pack
Black crystals rise, King Sombra joins the battle on the shore
And Tirek's wrath pushed every single soul to begin the war
Even Celestia and Luna cannot help to figure out what's going on in this eternal madness
The only one who is responsible for time is disappearing with her world in ethereal blackness

"Your magic of friendship has revealed something unknown
Ever since we exist we didn't know we were on our own"

"No
Stop coming back

You see what you've done
The time is collapsing on us

Now our home was destroyed
But we must stay strong and keep the things under focus

We've always acted alone

We've always been alone
This is the problem you've created -
Descending of our world
And now we need to keep the present, future and past separated"

"What?
It's not coming from here
Our kingdom
No
No"

"We didn't realize
This was not supposed to go this fast
"

"Nothing separates Equestria from our world now, and if we continue like this, there will be only oblivion"
