Within her royal palace in Canterlot, princess Celestia was still awake at this late hour. She had just received a letter from her most prized student that had recently finished her studies as her pupil. Nevertheless, she still enjoyed sending her reports, and princess Celestia certainly enjoyed reading them.

Dear Princess Celestia

I recently had a run-in with the most peculiar creature I have ever known.
It was a villain that didn't try to physically hurt me, or my friends.
To be honest, he seemed more like a teacher than a villain!
Not to judge a book by its cover wasn't even close to being the most important lesson he taught me!

In the end, he indirectly reminded me of just how much I value my friends.
He also taught me that no living being is impervious to corruption,
That being born with corruption inside of you is not a choice we get to make,
But whether to let that corruption grow or not is solely up to us.

I cannot even begin to recite all the things I learned from him!
He also urged me to learn from everything I do,
And that I would surely not succeed in my future endeavors,
should I fail to learn the lesson in every experience I go through.

Your faithful ex-student

PS: I thought you might want to know his name. He calls himself...

"Contrast..." Celestia whispered to herself with her eyes wide open from shock.

"Hello, Celly," a voice came up from behind her, seeping fear into her eyes. "Did you miss me?"
