Everypony has secrets. Some secrets are embarrassing. Some secrets are just things you don't want to share publicly with others. Other secrets can rock your relationship to the core if revealed...

-----
K'larra was a deep cover changeling sent to spy on Ponyville in preparation for the invasion. Sazzix was a survivor of the invasion that slipped past the wards and posed as an ordinary pony.

They fell in love.

Then they figured out they were both changelings.

Then they got drunk.

Ponyville is seen as a quaint little town by those who live there, and for Twilight Sparkle, it has all she needs with her friends by her side. When a stranger that she is familiar with comes into town, she finds herself questioning as to what to do and how to accept a secret they have held from her since they meet.

Sometimes, friendship is tested by what your willing to see as truth or lies. But how can one trust those who live with using masks to hide both lies and truth?

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.

There's only so much failure a changeling can tolerate. For Shade, once was enough. Years of training and preparation in the hopes of achieving a new life for himself and his colony wasted because of the negligence of their leader. It's time to try a different approach; if force won't work, then maybe peace and diplomacy will. What could go wrong?

A chance encounter in a creepy forest; A tree filled to the brim with books; A brief and sudden rain shower. These are all things that will change Shade's life forever.

This story is a sequel to Like Shattered Glass

UPDATED 12/22/2014.

Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?
