This story is a sequel to Mirror Equestria

“I can’t believe it… I’m back.” Twilight tilted her head.
“Back? Back where?” Sunset looked to her solemnly.
“Back home. In Equestria.”

Be sure to check out the prequel Mirror Equestria if you haven't read it yet, or else this story won't make any sense!

Note: This story is basically full of self-indulgent Headcanons for Sunset, since she's my favourite character and I just can't help but spoil her

[An AU where Sunset Shimmer never went through the mirror. The mirror portal didn't exist, and neither did the humans.]

When Sunset woke up to find herself in some part of Equestria she's never been before, she had originally planned to drive all the ponies apart in this place and gain more power to show Celestia that she's strong enough to be an Alicorn. But she didn't need to; all the ponies were already fighting with one another.

EDIT: Sequel is up now!
