On Shadows and Starswirls--A MLP Fanfic (Version 2)

This is the second "version" of the story I was writing last year, now with more plot and characters!

The first couple chapters will be the same, then a few plot points will start changing.

The Mane Six are happy to finally be able to take a break and relax after saving Equestria countless times. But all that changes one day...

Starswirl wants to see for himself how there's Equestrian magic on the loose in the human world, so he uses the portal in Twilight's castle. Upon his return, it's clear that something had happened while he was there, turning him evil. With it, he got the ability to unleash strange, metal creatures into Equestria.

Now, the retired heroes must step up once again to stop the creations and save Starswirl from what made him evil...before it's too late to do that.
