Dear Cozy Glow,
the Great and Powerful Trixie demands your attention!
Cozy Glow hadn't even read the first line completely as she already put the letter down. “Powerful? Golly, this is how you start a letter! Princess Nightmare Moon should take lessons from you!” she smirked. Then her eyes narrowed and a sly grin built up on her face. “Go on, Great and Powerful Trixie! You already have my full attention!”
Trixie has heard that you were a very naughty filly! Did you really manage to seize control of Twilight Sparkle's school all by yourself?! But Trixie does not write this letter to judge. No, Trixie is amazed that you succeeded with this!
“Oh, do you want me to teach you, Trixie? I can send you letters and explain you all about it! I can make you even Greater and more Powerful!” Cozy cheered.
Tirek stirred. “Yes, because that worked so well the first time we tried this.” His voice was ripe with sarcasm.
The veins on Cozy Glow's neck protruded again. “SHUT UP!” she scolded. “It was your plan that failed!”
The centaur shrugged. It was an intentionally unimpressed gesture. “I only told you what to do, the execution was on you and you failed horribly with that. Any pony you'd try to teach how to take over Equestria would fail all the same and end up here, annoying me even more!” He squinted and his eyes were burning with bottled-up rage.
Cozy Glow huffed audibly. “Just wait until I found a way to get out of here. What I'm going to do then will make you look like a roach in comparison!”
“Roaches are importunate.” Tirek's lips curled up into a vicious smile. Instead of giving another rebuttal, Cozy ignored him. More interested in reading on, she cast her eyes on the line where she left off.
And Trixie hopes that this letter does not make you angry. If it does, send your revenge to Twilight Sparkle. This is her idea, not Trixie's, and Trixie only writes you this letter because she owes Twilight Sparkle something.
But before you enact revenge, let Trixie tell you that revenge is a bad idea. Trixie knows, she tried. Twilight Sparkle bested Trixie in a magical showcase once. Trixie returned a few years later with the Alicorn Amulet after saving up enough money to buy it in one of Canterlot's dark and shady corners. Trixie beat Twilight Sparkle with it and exiled her from Ponyville. Then Trixie took over Ponyville and ruled over it as Great and Powerful Queen.
Cozy Glow whistled and a smile appeared on her face.
But the amulet also made Trixie become insane. Trixie still shakes sometimes when she looks at wheels. Don't ask.
After this, Trixie was suddenly really popular. Many ponies all over Equestria began to talk about Trixie, but not in a nice way. And some ponies still do that. Twilight Sparkle forgave Trixie and her friends forgave Trixie, too. Trixie even found a new friend with Starlight Glimmer! Today, the shows of the Great and Powerful Trixie have many ponies coming to them again, but a few never returned and they give scornful looks and whisper behind their hooves every time they see Trixie. Some ponies never forgive.
Trixie had to learn the hard way that being a villain is not worth it.
Here, the letter ended abruptly, close to the bottom edge of the paper. Cozy Glow frowned and folded in her ears. “Too bad..... This letter started so promising, but it ends on a really disappointing note!” Shrugging, she crumpled the letter and the envelope together and tossed the paper ball out of her cage. “Goodbye, Great and Pitiful Trixie!” she commented the gesture. Then she turned to a pile of small pebbles and started to stack them on top of each other, a deep frown on her face.

A few days earlier.....
“And you are really sure you want to send Cozy Glow the letter like this?” Starlight cocked her head and gave the mailbox that came ever closer a doubting glance before she turned at Trixie.
“Trixie is sure!” the other unicorn mare exclaimed.
“But you didn't write a whole lot and you came to the point so quickly. It would be better if you had taken some more time with it. And I'm not sure if it was the best idea to tell Cozy that some ponies will never forgive her for what she did.”
“I tried!” Trixie suddenly snarled into Starlight's face. “I am not a therapist, I did what I could!”
“Okay, then.” Starlight retreated, but with a raised eyebrow. “I really hope this won't backfire then.” Having read Trixie's letter, she was not filled with confidence. But before she could say more, the envelope had been thrown into the mailbox by her friend.
