It was late in the evening at Canterlot castle and Celestia was on her way to her bedchambers after another long day of political jargon.

She was not alone. Twilight and Luna accompanied her as she walked.

"Come on sister." Luna said "Young Twilight and I can lead the kingdom on our own for a century so, you can take your vacation."

"Thats right Princess Celestia." Twilight herself was nearly a full grown alicorn at 316 years of age. "You should take a century off, you led the land of Equestria for over one and a half millennium. You deserve a break. I mean you have a century of vacation stacked up! If somepony where to pay you that amount in holiday money Canterlot would be bankrupt."

"I don't know. Are you sure you two will be ok?"

"I think after 300 years of experience I can handle it by now."

"Very well, tomorrow I will start with the paperwork."

"Way ahead of you." Twilight said as she pushed a bunch of paper into Celestia's face. She studied it carefully and indeed everything was in perfect order. Tomorrow started her 100 year vacation. If Celestia didn't know better, she would have thought they want to throw her out.

"Everything seems to be in order."

"See, told you." Twilight's smile got even wider "You have nothing to worry about, just go enjoy your holiday. It will begin tomorrow! Good night." And with that they closed Celestia's bedroom door.

Initially, Celestia couldn't get the feeling of worry out of her. After a while she finally started to wander off into the land of dreams. She nearly forgot to take her regina off again. Maybe Twilight and Luna were right. Maybe she did need a vacation.

It was late in the night when a green portal made itself noticeable next to Celestia's bed and as destiny commanded it, at that exact moment Celestia rolled over and fell into the portal.

A explosion. It was expected but it still hurt Louise. Why couldn't it work for once?

"Damn it Zero! Are you trying to kill us?!"

"Told you the Zero would screw up."

"Montmorency, are you alright?"

This was her third try. Professor Colbert wouldn't let her try again. She would be expelled and her family would disown her. But right as she was about to sink into a black hole of self pity the smoke cleared and SHE was there.

Her coat was the most pristine white she has ever seen. Her mane was a radiant mixture of colors that flowed in the wind in a hypnotic way. A long white horn on her forehead. There was no doubt she had summoned a Unicorn. The purest of all creatures only a pure woman was allowed to touch one and harming one would curse one for all eternity.

And she was apparently asleep.

Her familiar didn't answer the first two times because she was sleeping.

Louise didn't know how to react to this.

There was whispering in the crowd around her but she couldn't hear it. Louise was too busy looking over what was apparently her familiar as she stepped closer.

She was a bit smaller than the normal sized horse and some of her proportions were wrong now that she took a closer look at her and she had a sun marked on her flank. For a few seconds Louise panicked that she may have hurt the unicorn with the explosion but the slow rising and falling of its midsections indicated that she was just a very heavy sleeper.

Louise could barely hold back her enormous smile. "HA, I told you I would summon the most amazing familiar, Zerbst." Her rival only had a bitter face at that.

"Yes, yes. We are all very proud of you for not messing up one spell in your entire live." In truth Kirche was about to turn green from envy.

"Miss Vallière! Please finish binding your familiar!" Colbert decided to interrupt them before another argument broke out.

Louise quickly hurried to her knees spoke a binding spell and kissed her familiar on the side of the head that was facing up.

Now normally foreign magic invading your body would hurt like hell, especially if the target of said magic initial didn't have any but to an alicorn this was nothing. The magic entered and hit a wall so solid you would need a equivalent of a anti tank rocket to even make it noticeable to whatever was behind it. To break this mental barrier you would need nothing short of something eldrich.

The runes didn't like it but they were outclassed and had no way to make this creature loyal to the caster. So they did the only thing they could and engraved themself on the barrier hoping to at least have some effect on the creature.

That effect was showing sparks of energy which were flowing around it like fireworks. Many took cover, but Louise just stood in front of her, biting her nails and praying that everything would turn out alright. Right as the intensity of the magic reached its peak, it suddenly went out like a candle and a set of runes was visible on her right forehoof.

Louise was so overjoyed that she didn't see her familiar, who had risen at the noise.

And with that all the cheerfulness in the air was gone. The unicorn's eyes were concealed by her mane, her head vas lowered and her stance was threatening.

It was so frightening that Louise was about to collapse and if had taken a look behind her she would have seen that everyone had noticed. The Professor and a few students had their staffs ready to unleash hell.

Louise didn't expect her new familiar to suddenly leaped onto her and drag her to the ground, abusing her like a pillow. The tense aura was dispelled so fast no one really knew what was going on, until Kirche decided to cut in with a snicker. "Why Louise, you are bonding awfully fast with your familiar!"

Louise herself had no idea what was going on till Kirches remark. "Shut it Zerbst."

"Well, that marks the end of today's class. I would suggest that all of you follow Miss Vallière example and use the rest of the day to bond with your familiars."

Louise was beet red but no matter the struggle she could not get out of the death grip that she was held in.

She was getting slightly desperate when she saw her classmates leave by floating away.

Only after she was completely alone and was completely sure that the Unicorn would not let go of her. She let out a weak cry for help.

Celestia was used to many things and through her millennia of ruling, learned to value words of wisdom like 'Always expect the unexpected' or 'If something is impossible then you have simply not found a way to do it yet'.

Many doesn't know this but Twilight got her checklist habit from Celestia and here was Celestia's checklist as of right now.

1. She was not in her bed.

2. She was snuggling a sleeping human.

3. She could not remember anything beyond going to sleep yesterday.

4. Her internal clock was messed up in a way that she couldn't even tell if it was time to raise the sun.

She recalled the discussion that she had with her sister and Twilight and tried to connect the dots.

After some thinking, she came to a conclusion that on her holiday, she drank alcohol then lost control over her alcohol intake. Found the magic mirror, used it, and broke it in the process. Explaining why she was still a pony and next to her was a human. The party continued until they landed in what appears to be some castle backyard.

Well no one could tell her she didn't know how to party if her assumptions where true.

Celestia started to shake her sleeping companion back into the land of the wake but only got murmurs back as a response. She started to shake harder to wake the pink-maned what she assumed was a girl.

"Huh…What?" Finally she got a answer out of her.

At first, Louise didn't really know what was going on. It was way too early to wake up and something had the gall to do so while she was snuggling onto the best pillow ever.

Only after her eyes adjusted did she realized that she was staring into the face of her new familiar. She took note of the large purple eyes and the worried look they had in them.

"Excuse me for waking you at this hour. But do you, by any chance, know where we are?"

…

After a few seconds of silence, Louise finally was awake enough to realize what had happened.

"You, you, you can TALK!?"

"Of course, I can. Now can you please answer the question. I don't really know where we are nor do I have memories of how I got here."

Louise cared for none of this. "My familiar can talk! Take that Kirche!"

Celestia was starting to get impatient with the girl. "I have no idea what you are talking about. Could you please answer my question?"

"You are my familiar. I summoned you as my companion and proof that I am a real mage." Louise explained with pride in her voice.

'Ok. I didn't got here the way I expected and apparently this female human summoned me to be her familiar.' Celestia reorder her thoughts.

"Can you please tell me now where we are?" She stood up to get a better look.

"We are at the Tristram academy of magic."

"And where is Tristram in relation to Canterlot?" Celestia was hoping that the town that Twilight visited beyond the mirror was called Canterlot because of the name of the school.

"Canterlot? Never heard of it." That was not good.

"You said something about me being your 'familiar'. What does that mean exactly?"

"A familiar is the extension of a mage that aids them with tasks like protection, transport, and finding ingredients for magical potions." Louise repeated after the book that her sister had sent her.

Celestia got slightly irritated at that. Did this little girl summon a ruler of a nation to be her pet? Of course she didn't show that on the outside, after all she still had no idea what exactly was going on.

"Why would you chose me for such mundane tasks?"

Louise got the impression that she may have offended her familiar. "I didn't. The ritual choses a familiar that fits the mage the best. Such as a wind mage getting something that is like a bird or an earth mage getting a mole." Louise again explained according a book.

Ok. So she was summoned by accident or fate, if this girl's words where to be believed, and apparently there was some unknown type of magic here that she didn't know of. Was earth magic somehow related to earth pony magic and wind magic to pegasi? Speaking of which, her magic felt strange somehow, as if it was trying to burst out of her. So many questions she needed to answer. For now, she should try to get on the good side of her summoner. A friend would always be helpful.

"Well, my name is Celestia. Nice to meet you."

"I am Louise Françoise Le Blanc de La Vallière. Your new master!" Celestia had a bad feeling about this familiar relationship. Hopefully Luna and Twilight were not worried about her absence. Even when she was supposed to be on a vacation right now, you could never know.

"Are you absolutely sure she is gone?" Luna asked.

"100%."

"She is not anywhere inside the castle?"

"She is no where close to Canterlot!"

"Have you checked the hidden rooms?"

"Untouched."

"Toilets?"

"No sun on any of them."

"So we are, without a shadow of doubt, completely alone in the Castle" After Twilight affirmative nod. Luna couldn't hold herself back anymore and threw Twilight into her bedroom before sealing it.
