Dear [Insert],

The sounds of a quill scratching against paper were heard, Celestia eyeing the piece of parchment in front of her trying to come up with ways how to start a letter with someone after so long of being distant over paper. She was merely doodling whatever on the piece of paper as she waited for her thoughts to naturally flow.

Her body was warm, the fiery colors of red, orange, and yellow oscillated on the other side of the room as her fireplace. It spread warmth and light all throughout the room.

Dear Princess Twilight,

She gently put down her quill, thinking that it was too formal. She wanted a good-natured relationship between the two just like always even if Twilight would most likely blow up for her role model.

And so, she put a line over the word 'princess' before scrunching the whole parchment up into a ball and throwing it into a nearby trashcan. Getting out a fresh new one, she started writing again.

Dear Twilight,

How have you been? I'm sorry we haven't been in touch lately. So have you got any interesting stories you would like to share? Knowing you, you would probably like to but I don't know if you've changed that about yourself.

I'm sorry for not being there. Keeping being you.

Yours,
Celestia

Celestia smiled and nodded, rolling the parchment up into a tube before dematerializing it away out the window in green flames using her magic. She looked out the window to see the little town before her.

A scroll interrupted Twilight's view as Spike burped it out, lifting up her head from her book. She took it in her magic and started reading through it. Seconds later, she lowered it down and frowned.

She turned to Spike, entreating him to go fetch for some quill, ink, and parchment.

In a flash, he went away. Not even a second went by, Spike came back with the following equipment he was asked to bring to her.

Twilight levitated the items and thanked him with a smile before turning to her parchment, trying to think of what to write. She wasn't normally speechless but since it was about a letter from her role model telling how they've been distant lately, Twilight didn't know what to say.

And so, she merely went with whatever came to mind.

Dear Princess Celestia,

I have been good, actually, but could be better if I had you around in my life still. But it wasn't your fault so don't blame yourself. I'm sorry for not writing letters to you after you made me into an alicorn but may I ask: what took you so long exactly to tell me that we've been distant?

Anyways, I was just separating Applejack and Rainbow Dash away from their little arguments again. Even if I'm not an AppleDash shipper, I still don't want my friends arguing.

I'm more or less a Rarijack shipper. Heck, you remember that sleepover I had with them? That's when I started dreaming sex dreams of them. Ask your sister. She told me she enjoyed them too.

Yours,
Twilight

Signing off with her name, Twilight hoofed over the scroll to Spike to have him breathe green flames over it and send it out the window, waiting for a reply from the princess.

Celestia lowered the letter down and began writing down her reply.

My Dearest Twilight,

I fear my sister had already told me about the sex dreams of your two friends. As horny as my sister is, she told me she wished she had some sort of device that allowed her to record ponies' dreams. While I'm also a Rarijack shipper, I prefer to respect ponies' privacy.

I've also forgotten to tell you that when you became an alicorn you start to feel a sense of horniness inside of you. Your body is developing and maturing but it's nothing to worry about. Think of it as going through puberty all over again.

Your Former Teacher,
Princess Celestia

Letting out a chuckle, Celestia rolled her parchment up into a scroll and used her magic to send it out the window in literal green flames.

In a spark of golden light, Celestia's magic took hold of a book lying somewhere in Twilight's castle library as she had given to her for her two former pupils to write with each other about an ancient threat occurring until they started eagerly writing back and forth.

Celestia hugged the book tight, memories pushing into her mind. She looked at the front cover where an image of her cutie mark was designed upon.

She smiled, flipping through its pages where her two former pupils were writing to each other but then flipped to the very front where Celestia herself was writing to Sunset Shimmer herself before having to let her go to another world.

A frown wrinkled up her face and she sighed. She picked up her quill, dipped it in the inkpot, and started writing on a fresh new page in the journal.

My Little Sun,

I know it's indignant of me to try and talk to you after so long of not, but I just want to let you know that I'm sorry. Sorry for being impatient towards you when you tried so hard, so hard to make some friends.

I'm sorry I didn't see this.

But anyway, how have you been doing over there? It's fine if you don't write back, but anything would be great just to hear you rambling on a new spell learned, you laughing at your own jokes...

I'm sorry. I screwed up.

Signed,
Celestia

Dealleviating the tension off her shoulders, Celestia brought out a big breath and waited for a reply, hoping so desperately that there would be one.

From the other world, Sunset was laughing at a table with her friends all around. Suddenly, something vibrated in her bag causing her to stand up and excuse herself from the table.

She went somewhere where she could find it private and peaceful.

Taking out a book from her backpack, the book lighted up golden and not like the magenta that she had always been receiving. This one was where she had never been received in such a long time judging by the wrinkles forming on her face.

Dear Sweet Celestia...

A part of her still felt angry towards her mentor for bringing this faith upon her, but another part of her felt grateful. Grateful that she was able to make a wonderful group of friends all because of her mentor and... Twilight who she was jealous of.

Sunset took a breath and got out a pen, clicking it and writing some words down on the next side of the page.

Princess Celestia, I... I'm so sorry. I'm sorry for turning my back against you, I... It wasn't your fault! So stop blaming yourself all the time. It was I that said all those things towards you, I... didn't mean them.

I... was just so, so angry. I know I had the right to be, but... it was no excuse for my poor behavior against you.

But I'm on a new page now. But it's always been empty without you on my side but now you're here. So thank you. This message meant a lot to me, reading it.

Thanks,
Sunset

Sunset smiled through her teary face, the free-flowing tears that were strolling down her cheeks were being wiped away, and went back to join her circle of friends.

The scroll blasted out from Spike's mouth as he burped after he finished draping a blanket over the alicorn's body sleeping on the couch.

Not wanting to wake her up, Spike took this upon himself to reply to the princess himself.

It has been a long time between the three of them.

And so, Spike got out a quill, ink, and parchment before letting thoughts flow through his mind to write them down on the piece of parchment, dipping the quill into the ink.

Dear Princess Celestia,

This is Spike writing to you as Twilight is unavailable to do so as she is currently sleeping so I have taken this upon me to catch up with you that was also my teacher. And don't worry. Twilight adored you ever since she was a filly and still does. There's no way you'll ever be able to disappoint her.

I'm pretty sure Twilight would go insane when she finds out she didn't know about something before.

But... I don't know if it's a wing-creature thing but when I got my wings I started feeling horny ever since then too.

Mostly towards Rarity, obviously.

Anyways, we never did talk to each other that much, did we? I remember when Twilight hatched me you took me under your wing before giving me to Twilight to look after herself as part of a 'test' for her. You said I was too much of a claw full. Heh. Who could blame you?

But I feel as if you focused too much on Twilight that you forgot to focus on me too.

Shining and Twilight never thought of me as their little brother, just a friend or pet or companion or assistant or slave or sex slave. Heck, there are so many things to call me apart from 'brother'.

I'm sorry. For ranting. Towards you. It's not your fault.

Your Equestrian Dragon Citizen,
Spike

Spike wiped his tears away and slowly smiled before breathing green flames over the rolled parchment, sending it out the window as he laid down next to Twilight on the couch.

When Celestia put down the letter, a string of sorrow and regret washed over her. She never really could remember the time when he was in the picture with her and the others. It would always just be Celestia and Twilight with her friends.

A frown marred her face, lifting a quill into the air and dipping it in the inkpot before jotting words down on the flattened out parchment.

Dear Spike,

I'm sorry.

Yours,
Celestia

Celestia sighed and rolled the parchment into a tube before dematerializing it into green flames out the window, settling herself on the rug beneath her and ruffling her wings. She inwardly declared to herself that this was going to be the final letter she would send for today.
