As silently as a ghost you dart from shadow to shadow, mentally counting down the time you had until the next guard patrol would pass by the base of the castle's rampart.

four...

Three...

Two...

One...
A unicorn guard passes by, Shining a light back and forth keeping careful watch for intruders.

Not carefully enough, you think to yourself.

Waiting until the guard is out of sight, You reach into your backpack and remove a grappling hook and a long coil of rope.
Twirling the grappling hook over head you give it a toss and watch as the grappling hook disappears over the castle wall taking your long coil of rope with it.

"Crap!" You bring your Palm up to your face with a loud slap.
Next time don't let go of the rope, you think to yourself.

Reaching into your pack you remove a second grappling hook and another long coil of rope. You then proceed to repeat the action of twirling your grappling hook overhead and then tossing it over the wall, while this time firmly holding onto the end of the rope in order prevent your previous mistake.

With your rope now firmly secured, you begin scaling the vertical wall with all the grace of an out-of-shape spider and once you finaly Reach the top of the parapet you collapse in a heap, gasping for breath.

Once you finaly regain your composure, you take in your surroundings. All of Canterlot lays before you, it's city lights twinkling brightly.

Leaping from the parpet you silently land on the roof of a nearby building. The city streets are narrow and you can easily jump from rooftop to rooftop without any difficulty whatsoever.

You continue your moonlit journey towards the royal palace appearing as nothig more than a deadly silhouette in front of the full moon, Your shadow trailing silently behind you, like a phantom in the night, leaving no indication whatsoever that you were ever even here.

Until you step on a loose roof tile and slide uncontrollably to your doom in the city streets below.

Earlier that day in canterlot. Princess Celestia was enjoying her afternoon tea accompanied by her sister Luna.

"Dear sister you seem rather melancholy of late is something troubling you?" Luna asked her sister.

After a moment of silence Celestia let out a long sigh of desperation, "I'm just a little lonely is all Luna."

"What reason have you to be lonely dear sister? You are adored by all your subjects and I am here as well, rest assured you are quite loved" Luna reassured her sister.

"I love all of my little ponys and you too Lulu" Celestia said, placing a hoof on her sisters withers, "But I crave a more physical
relationship."

"Ooh..
Ooh my....
Sister I had no idea you felt that way about me.
I...I mean I hadn't realy thought about ....us in that way.
I mean we are sisters After all. Wouldn't that be incestuous or rather princestuous in our case?
I am realy quite... unsure but if you realy want to try I guess I'd be willing to give us a chance for you Tia." Luna stammered.

ppffffftt! Celestia spat a mouthful of tea across the room "Luna! That isn't what I meant at all,
I mean your a wonderful pony, And... I'm not saying It could never happen, but that realy wasn't what I had in mind." Celestia said using both hooves to cover her blushing cheeks.

"Oh good, Because to tell you the truth I was a little uncomfortable about the hole idea." Luna said making a rude gesture with her hooves and winking at her sister to ease the tension in the room.

After a long awkward silence Luna finally spoke up and said, "Surely we can find you a special somepony among our subject's.
Perhaps we should host a grand ball or a gala, Some kind of party get you out there and mingling."

"It just isn't that simple Luna, They all think of me in a motherly sense.
And surely you've noticed a certain anatomical difference between them and I."

"Hmmm... You have wings and a horn?"

"IM FREAKISHLY TALL LUNA! I tower over everypony.....I feel like a monster sometimes." Celestia breaks down sobbing. "Sniff...Sorry Luna I didn't mean to snap" Celestia apologised to her sister, wiping away her tears with a napkin.

"There, there, big sister don't cry it isn't all that bad is it." Luna said cheerfully.

"Luna, Imagine throwing a carrotdog down a hallway coated in lube." Celestia deadpanned.

"Oh it realy is that bad after all." Luna said staring off into the distance, realising there are certain things you can never un-imagine.

"All is not lost though sister" Celestia said tilting her head as she fondly reminisced,"A few months ago I was running late for my day court and I bumped into someone, he was tall, handsome and strong, but unfortunately, he was also unconscious. So i never realy got his name. And by the time court was adjourned he was gone. And I have no idea were he went."

"It wasn't that pretentious minotaur Iron Will was it" Luna asked in a concerned tone.

Both sister looked at each other scrunching their muzzles adorably and exclaimed "Eww gross" in unison, before rolling on the floor completly devolving into a fit of girly giggles.

Once the two sisters recovered from their random fit of silliness Luna turned to her sister and said, "Tis good to see you smile again Tia. I mean really, Sometimes you make me feel like the older sister, Always cheering you up and whatnot."

"Which reminds me dear sister I've taken the liberty of hiring you an assassin." Luna said is if she didn't just threaten her sisters life.

Celestia sternly glared at her sister, "I swear Luna I will send you right back to the moon!" Ceslestia said raising her voice while pointing a hoof at her sister.
"I thought we finally put all this foalishnes behind us."

"Tia it's not like that" Luna explained.
"The guard's have been getting restless lately. They've been complaining that there isn't anything to guard against. Things are a little too peaceful to suit them, So I've arranged a little training exercise."

"I've explained every thing in my letter this morning, And he should be here tonight. The guards are already making preparations, And he knows we'll be waiting for him."

"Doesn't this seem just a teensy bit dangerous Luna?" Celestia asked her sister.

"Nonsense Tia, Nopony would ever realy harm you."

"Luna I can quite handle myself if it should ever come to blows." Celestia reassured her sister.
"It's your assassin that I worry about, The lunar guard can get a little over zealous sometimes. They might actually kill somepony."

"I must admit they can be a little over the top sometimes, But the pony I've hired is a highly trained professional.
Pony's say he can melt into the very shadows themselves and silently strike without warning before disappearing without a trace.
I'm confident he'll be more than a match for canterlot's elite guardsponys." Luna told her sister beaming with confidence." And don't pretend that you yourself aren't eager for a little action dear sister."

"Well I suppose your right Luna, And this might be a good chance to blow of a little steam. Just as long as nopony gets hurt."

Both sisters jumped around the room in excitement for all the fun that tonight would bring.

Author's Note

No I didn't misspell whole, Luna made a dirty joke.

P.S. it seems that great minds think alike for Gimmick68 also wrote about Celestia complaining that she's freakishly tall in the story After Words wich was featured feb 27 2020.
