Dear Starswirl, Legendary Teacher of Equestria's Princesses!
I have waited for a letter from you with great anticipation, so I can learn and benefit from your wisdom. But, oh, you made such a terrible mistake by suspecting your friend Stygian and betraying him, I was so shocked to read about this! You are such an ancient and wise wizard, I thought mistakes like that would never happen to you.
But it's fine, Cozy has made a mistake, too. I betrayed many ponies who could have been my friends. They all thought I was honest and then they learned I was just using them. This was so awful and I regret it.
We both did awful things, didn't we, Starswirl? But we learned from it. Cozy has learned from everything bad she did and changed!
I had noble intentions with my plan, just like you said, and there is a lot of good in Cozy Glow! You will see everything of it, once I am out of this dark and scary prison!
We understand each other so well, Starswirl, I can see that when reading your letter. I am sure you will put in a good word for me when you talk to the princesses... right?
Yours faithfully,
Cozy Glow
