War. War changes everything. It affects everyone. Those who are not soldiers fight to supply them. Those who remember peace kill to find it again. Those who lead the charge die in the crossfire. Moral or physical, the sacrifice is the same, and everyone must make it. In war, every foe vanquished is a friend lost; a lover taken; a family torn. Every nation that falls is a people destroyed, and at the end of the war between Ponies and Zebras the people of Equestria were nearly annihilated. The survivors retreated into their Stables, condemned to eke out an existence in twisted societies, while outside a nuclear winter dragged on throughout decades. Not all people were so lucky.
For the Changeling Empire, the war spelled out a more certain death and doom than for any of the ponies caught in the balefire. All love had been drained from the world, and so, faced with extinction, they vanished to places unknown. Now, a lone worker has awoken, confused and alone, to try and find love in a land filled with hate...
Fallout: Equestria - Change
It's not a very good idea to have a prologue this short with nothing else. Should have been a part of the first chapter.
So lets begin reading this story. There are to few changelings in the wasteland, so always nice to meet a new one.
As Half-a-Yolk said, this is way way to short. A good prologue are minimum 500 words long, just enough to actually say something but not beginning to drag out. Another important thing is to hook your reader, to throw something out to us that are different from all the other stories. To show us what makes your story special. Sure you have a changeling, and say that, but the way that you say it make it sound like a fact. That your main character just is there instead of making it personal and us the readers curios.
I would say re do it all. Sit down and think over what there makes your piece of the wasteland into yours and not others, and then write this again.
this prologue sounds like it should be the description
