Tempest Shadow or Fizzlepop Berrytwist as her closest friends and allies know her as, is a dark purple, damaged unicorn. The reason why she is damaged is because when she was a young filly she was attacked by an Ursa Minor while chasing after a ball for her friends. This ended in her losing her horn and getting a scar across her eye as well.
Since she had lost her horn, the two friends she had abandoned her, and she was left alone and soon became the Commander of The Storm King’s Army. Soon she was betrayed when he got what he wanted and didn't restore her horn. But because of this she turned good and saved Twilight and her friends. After that she was given a second chance.
Ever since the Friendship Festival, and Twilight's offer to become her friend, Tempest Shadow has tried her best to make up for her previous mistakes, and help rebuild Canterlot. She has also tried to make new friends. This has proved difficult for her since she has not gotten a good reputation from attacking Canterlot. It also doesn’t help that her broken horn has made many ponies too scared to come near her.
However she has been able to make a couple of friends since the festival. She is good friends with Twilight and her friends now. And is also good friends with Starlight Glimmer and even Princess Luna since the three of them had all been through similar scenarios.
Twilight and Tempest had become really close to each other since the festival. One day Twilight had been invited to visit her at her new house in Ponyville. Which she had gotten thanks to Princess Luna pulling some strings at Canterlot.
Twilight walked up towards her house and knocked on the door. She thought to herself quietly as she waited for Tempest to open the door. “Ok Twilight stay calm, she's a friend, a close friend and she is nervous and scared to make new friends."
Twilight was knocked out of her thoughts as the door opened. The sight before her made her stifle the gasp that tried to come out, as for the first time since they ever met, Tempest was without her black armour on her body. As Twilight saw her purple fur, and saw she was quite attractive even without the armour.
"Twilight it's so good to see you again. I’ve been wanting to talk to you for a while, please come in."
Tempest said happily as Twilight walked in and looked around her house. Twilight was expecting it to be a dark place, but she was wrong as she saw the room was bright and happy looking. Tempest walked past her and went to the sofa to lay down on it, as Twilight slowly walked over and laid on a chair nearby.
"What is this, a therapy session?"
This made Tempest laugh, slightly looking over to Twilight.
"It could be Twilight, it's just my horn."
Tempest said choking on the last part of her sentence, as she felt her horn making the it’s usual sparks. Twilight looked down sadly wanting to do anything to cheer her friend up.
"I wish there was something I could do for you Tempest, I really do but I don't think even Starswirl The Bearded would know how to make a horn fully return if it’s broken. I have been researching for any leads but got nothing."
Tempest smiled softly at the panicking alicorn. She had found out from her friends that Twilight panicked quite often when it came to most research projects. "It's okay Twilight I'm thankful you are even attempting to find a spell to help me.
Nobody else has ever done that for me. I’ve got to admit those words you said to me at the Friendship Festival have stuck with me ever since."
Twilight tilted her head and gasped, remembering the words she had said to her that day. She was surprised Tempest had remembered those words.
"Wow Tempest, I didn't think they would have that much of an effect on you. I did mean what I said though. Even if it's broken it's a very powerful horn just like the mare it’s attached to. You sacrificed yourself to protect me and my friends."
Tempest listened to Twilight and smiled happily. That she had brought her back and not kept her in stone despite what she had done. She didn't want to admit it, but she admired Twilight, and was happy to have a friend like her.
"If you’d like Tempest, perhaps we could arrange some magic lessons, and see what your horn can do. Maybe we could find some spells to work around with. That way you can use it like you use to."
Twilight's offer made Tempest think for a few seconds, before nodding towards her friend smiling.
"Thank you Twilight, that would be really kind of you. Though, I don't want to interrupt your plans with your friends." Tempest replied pawing the sofa with her hoof, feeling a hoof on her shoulder she saw Twilight smiling at her.
"It's no trouble Tempest, besides maybe Starlight can help us out. You could also send some letters to Princess Luna. Maybe she would have some advice for you as well. I know you three get along well, and they would love to help you too."
Tempest couldn't think of anything else but to hug Twilight, so she did expecting Twilight to push her back. but then she felt her hug being returned as they stayed that way for a few minutes. The moment ended when Twilight spotted Tempest’s armour and walked over to study it as Tempest watched her.
"If you like Tempest, I could ask Rarity to alter your armour. Maybe get The Storm King's mark off of the armour for you."
Twilight offered as Tempest walked over. She smiled and put her hoof over the mark, then looked at Twilight.
"I think I want to make this symbol a symbol of hope, instead of fear. What do you think Twilight, become Ponyville’s Royal Guard?" Tempest proposed making Twilight smile. She thought about it before looking at Tempest, and the armour. Then her eyes lit up.
"That's a great idea Tempest, becoming the Commander of Ponyville’s Guard. That will show you are turning over a new leaf, and want to help ponies not harm them. You even already have experience doing it!"
Twilight said excited, grabbing a quill and paper to write to Celestia making Tempest chuckle seeing how excited this idea had made Twilight. Continuing to watch her she watched her write like a machine. This made her think, "Wow when she writes she really goes at it that's sorta cute actually." Tempest watched as Twilight put the newly written scroll in her saddlebag to ask Spike to send to Celestia when she got home.
"Alright Tempest why don't you come over tomorrow, and I'll tell you what Celestia says. After that we can start those spell lessons, I’ll also Luna if she has any ideas for you." Twilight said as she walked out of the house as Tempest watched her leave. Once the door was shut behind her Tempest walked to a mirror looking at her horn spark again which made her give a smile.
Maybe you’re a blessing dear horn. I think I may like her more than just a friend. I hope she might feel the same. Tempest thought to herself not knowing that Twilight was thinking the exact same thing as her.
