The mane six walked back into the throne room and saw Satania was currently still asleep in Twilight's throne with her legs still crossed and her hand still over one eye in order to look cool. Twilight looked back at her friends and whispered, "Now let's see if the spell worked," she then spoke up and said, "Miss Satania we are ready to hear you story."
Satania then woke up and had her smug look return to her face, "Ah yes of course, I was just busy meditating in order in to contain my vast demonic power," soon after she finished saying that all of the mane six heard (I fell asleep because you left me in this boring room alone) in there head confirming that the spell did indeed work. "Now it all started when I graduated from demon school with highest honors (barely passed) and was sent to Earth in order to spread evil and chaos among the mortals." The mane six sat for a few seconds waiting for that to be translated into the truth and when it wasn't they were all shocked.
"WAIT YOU REALLY ARE AN EVIL DEMON!" said Rainbow Dash.
"YOU MEAN THIS SILLY FILLY WAS TELLING THE TRUTH!" said Applejack.
"AND WE PROMISED TO HELP OUT A MONSTER LIKE HER!" said Twilight Sparkle.
"Actually it is not that surprising or bad at all," said Fluttershy.
The others simply let out a collective "WHAAT!" and stared at her.
"Miss Satania you said that this was the job of you and all other demons, can I assume that there are also beings meant to spread order and goodness among Earth's mortals?" said Fluttershy.
Satania looked a little surprised before saying, "Yes those are the angels like that detestable Gabriel but I will get to her later. How did you know about that?"
"Oh I have a friend named Discord who has a similar role in our world," she then looked at her friends and continued, "I forgot to tell you all this but not too long ago Discord tried to act completely normal at a tea party to impress me and he started to fade away. I had to cause chaos in order for him to reaper and afterwards he explained that there are immortal beings like him who simply must cause chaos and immortal beings like Celestia who absolutely must maintain harmony. Booth need to exist in order to maintain balance in the universe and if either one were to quit doing there job it could lead to untold disasters. He said the reason he was disappearing is that in this universe if one of them stops doing there job said being well be erased and then simply replaced with a new one. Considering you haven't been spreading any evil since you got here but haven't faded away either I am guessing that it doesn't quite work the same way in your universe but it's the same basic concept right?" said Fluttershy before looking back at Satania for confirmation.
Satania smiled and said, "It makes me happy to meet a mortal who truly understands the beauty of my demonic works." (I am glad you understand it my teachers used to go on and on about that balance stuff and I never really got it)
"Well if it's necessary for the survival of her universe I guess it's ok," said Rainbow Dash, "What do you think Twi? Um Twilight?"
Twilight just stood there dumbfounded at all this new information. Celestia and Discord are polar opposites of each and booth are needed for our world to exist she thought. But what about when Discord was in stone? Is that why so many villians like Sombra and Nightmare Moon only first emerged after Discord was in stone? Because the universe was out of balance and the resulting issues corrupted ponies? She then snapped out of it and decided she would ask Celestia all these questions some other time. "Sorry. What you do may not sound appealing to us Satania but we understand you need too do it. We are sorry for judging you and would like you to continue your story."
"Of course. Now then I was causing the most evil and demonic acts all across the world (I was pulling pranks at my school) such as undercutting there economy, ridiculing there knowledge, and ruing there environment (switching the price tags at stores around, ignoring my homework, and throwing recyclable trash in the nonrecyclabe bin) I was on the fast track to being demon queen and absolutely no one could stop me." (I was barely meeting my quota of bad deeds and had my pay cut a couple times.)
Everyone in the mane six did there best to stifle a laugh at hearing what Satania thought was evil deeds. Rainbow Dash almost couldn't contain herself but Applejack nudged her hoof and made her hold it in.
"Ah I see you are all on the verge of tears at hearing all my dark deeds," said Satania who seemed to have no idea these were tears of laughter as evident by the fact that there was no translation afterwards. "Unfortunately these did not continue as soon an angel by the name of Gabriel showed up to ruin all I have done. She spites me by doing the same deeds as I but with some kind of goody angel twist to make them good and make me look bad. (She does all the same stuff I do without even trying or really even caring.) And whenever I attempt to do something to destroy her and her goody ways (to mess with her and ruin her day) she uses her advanced angel magic to undo my work before it even affects her and sometimes even turns it around on me. (she simply does not care no matter what I do to her and will sometimes trick me into turning my prank on myself). She even tricked my greatest comrade Vigne into joining her cause and spreading good. (Vigne keeps trying to get her to act like a proper angel to maintain the balance and because she liked doing good deeds to begin with). Moreover she has a comrade named Raphie who seems to a demon acting as an angel as she always messes with me and causes chaos." There was no translation on that so it looks like it's true. "After several failed attempts to best Gabriel i finally found the perfect way. Through great study I learned of a spell to enter heaven the home of the angels (I saw it for sale on the late night demon shopping network) I planned on using the spell to go heaven will I infiltrate Gabriel's fortress and bring it to the ground and make Gabriel writhe in agony. (I would break into Gabriel's room and threw out all her clothes and replaces them with ones that are slightly too small so she will be uncomfortable all day without realizing why and maybe think she's getting fat.) But unfortunately something went wrong with the spell and now here I am."
"Hmm I see. Will if that's it I think we can help you." said Twilight.
"Really? And what can you ponies do for me?" said Satania.
"Well I can make you a fresh new ensemble that will truly fit a demon queen," said Rarity.
"I can help you do better pranks, I mean dark deeds, on that Gabriel girl," said Rainbow Dash.
"I can help you build up your strength by working on the farm so you wouldn't have to complain about anypony being stronger than you," said Applejack.
"I can talk to Discord and together we can explain more about the balance and how demonic energy works so that you can expand your influence and improve your work," said Fluttershy.
"OHH. I can show you how to make awesome cakes, and pies, and muffins, and throw amazing parties," said Pinkie who then paused for a second before remembering who she was talking too, "Um. So you can win over the hearts of mortals so they will join your side and follow your cause," she said with a somewhat nervous smile.
"Hmm I'm not sure if I need your help but I guess it couldn't hurt," (OH THANK YOU SO MUCH I NEED ALL THE HELP I CAN GET) said Satania.
"And of course I can take a look at that portal spell card of yours to try and fix it so it can send you home after we're all done," said Twilight Sparkle.
Satania pulled out the card and Twilight grabbed it in her magic. "Just be careful, there is some powerful demon magic in that," (I spent a lot of good yen on that so you better not break it) she said. "Now then your new queen is tired from this long day (that nap wasn't enough) where might I lay my regal head."
"Ohh. I have plenty of guest rooms here in the castle. There is one just down that hall and to the left if your OK with that." said Twilight as part of her hoped maybe she wouldn't be OK with it and have to stay somewhere else.
"That seems fine," said Satania who then began walking to the hall Twilight indicated, "Goodnight pony creatures. I will see you all in the morning when you begin serving me." (I am looking forward to your lessons to help me tomorrow) She then walked away.
Rainbow Dash then jumped in front of Twilight and with an intense stare said, "OK you have to remove that spell from her ASAP."
"Why?" said Twilight.
"Because if you don't I don't think I am gonnah be able to keep myself from a laughing whenever she talks," she said before finally giving way under the pressure and laughing on the floor. Honestly everypony else was surprised she held out for as long as she did and silently agreed with her.
