A pegasus filly, a bipolar unicorn, and a changeling walk into a bar.

Twilight Sparkle: a name often associated with magic, friendship, harmony, and most recently, ascendant princess of Equestria.
Nopony, not even herself, could have thought that she would be a changeling.
Especially not a changeling princess.

This story is a sequel to Becoming One With the Night

It was supposed to be a good day. Twilight and Luna were sharing the news of their relationship with their closest friends and family. However, Celestia's largest secret yet finally came out. Now, relations are strained between Celestia and everypony else. After all, what's Twilight to do when she finds out her second mother is actually her birth mother?

On top of this massive bombshell, soon Twilight will be sporting a pair of wings of her own. If she thought things were complicated now, just wait until Canterlot gets wind of a new alicorn. Life is about to become one giant nightmare for Twilight. But hey, at least she has Luna, right?

As stated above, this is a sequel. I highly encourage you to read the first story (the writing is extremely rough early on, mind you), but it's not entirely required to understand most everything that will be going on here.

EDIT: Takes place during S3, when it was originally conceived, thus the Alt. Universe tag. There was no redemption of Discord. There was no ascension. Yes, the Crystal Empire is back, and Cadance and Shining Armor are the leaders there. This should cover the more critical aspects of the season in regards to the story.
