As soon as they headed into the library Starlight and Spike began looking for books on fertility spells. While Spike pretty much knew where every book was from his time with Twilight, Starlight had no clue to look as she never had any interest in such spells. She asked, "Spike, where did Twilight keep the books on fertility spells?"
Spike replied, "They were in the far right corner in the middle."
The two headed to that area but much to their dismay they were no longer there. Spike sighed, "I have a feeling that Trixie either made Twilight remove them or she rearranged everything while she still had the wits about her to do it."
Starlight glared at the massive amount of books and grunted, "Well it looks like we're going to have a very long search on our hooves. You start looking on the left side and I'll look on the right side. If they aren't there, we'll look in the back."
When Starlight mentioned the back, something crossed Spike's mind, "Starlight, before we go looking through everything, what if Trixie had Twilight put the fertility spell books in the back in case something like this was to happen?"
Starlight replied, "Spike, you're a genius!"
The two headed to the back of the library and began to search. At first they were becoming frustrated. It was at this point that the nagging voice in Starlight's head said that they would be on the very top shelf. Starlight flew up there and found many books on fertility spells so she brought them all down. She asked, "Spike, do you remember which one it was?"
It did not take Spike long to find it as he was able to point it out easily, "Starlight, this is the one."
Starlight opened the book and began to flip through the pages. She was mumbling to herself, "Let's see, futa spells, energy spells.....oh here it is, spells involving horns!"
Starlight opened the book and began to read through the various spells wondering which one Trixie used. She kept on reading until she hit a part she did not expect to find, counter spells. "Spike, this is it! Counter-spells!"
Spike looked at the book and replied, "This is great! Now all you have to do is cast the counter-spell and Trixie won't be able to get Twilight pregnant again."
Starlight sighed, "That is true but I will need to channel my energy into the book so I'll know what energies to use and after that, I'm going to have to write a reversal spell from scratch to free Twilight from Trixie's control."
Spike replied, "Well if anypony can do it, you can Starlight!"
Starlight said, "Thanks Spike. I appreciate your confidence."
Starlight began to channel her energy into the book for the counter-spell. Her eyes began to shine white as she realized what type of energy would be required. After a minute her eyes returned to normal. She said, "Well I know what type of energy to use, now comes the hard part, writing a spell from scratch."
While Starlight had used mind control magic before, the type she used would not work in this instance and even if it would, she knew that nopony would approve of her taking Twilight's cutie mark. She sat down deep in thought with her head resting on the table. She seemed to go into a trance like state when she shot up and said,
"For the pony free will is a thing of the past
But this can not last
Freedom is what the pony needs
So she may see where life leads
The time has come for her to think as a whole
So that what can be fulfilled is her role."
Spike asked, "Starlight, do you think it will work?"
Starlight replied, "Well we're about to see. With any luck it will. I just hope that if it doesn't it won't make it impossible to save her."
As they were headed back up stairs Spike asked, "So which one are you going to reverse first?"
Starlight replied, "I will reverse the fertility spell first but I will have to do it outside of Twilight's room. I have my concerns as to what seeing something bad happen to Trixie in front of her might do."
Spike asked, "You mean like she might try to attack us?"
Starlight replied, "Yes and not only would that not be good for our cause to free her, it might harm her unborn foal and I certainly don't want to be responsible for that."
Once they arrived in Twilight's bedroom Celestia asked, "Starlight, do you have any spells ready?"
Starlight replied, "Yes, I do." She glared at Trixie and ordered, "Follow me, I shall handle you first."
Trixie laughed, "Trixie shall follow you but Trixie is not worried because no spell can reverse The Hot and Dominant Trixie's fertility spell!"
Trixie followed Starlight out of Twilight's bedroom into what used to be her bedroom. Starlight figured that it would be a slap in the face to Trixie by doing it in her old room given that is where she wanted Starlight to cast it upon her. Starlight pointed at her old bed and ordered, "Trixie, sit down."
Once Trixie sat down Starlight lit up her horn, pointed it at Trixie and recited,
"While the mare enjoys spreading the seed of life
by doing this she has caused much strife
normal this is not
it is despised by a lot
this ability can no longer be
free from the father's role she shall now be."
Starlight fired a powerful bolt of energy encircling Trixie in a bluish-white light. Trixie began to scream and yell as she felt her horn begin to return to it's normal size. Once the spell was complete Trixie fell onto her side. She could tell that the spell worked and was not happy about it, "Starlight, how could you just do this to Trixie? The Hot and Dominant Trixie didn't do anything to deserve this."
Starlight stared her down, "Trixie Lulamoon, you used this spell to impregnate Princess Twilight. Not only was that wrong but from what I understand it is also illegal." Starlight headed out of the room and locked Trixie in. She headed to Twilight's bedroom where she announced, "Well it worked. Her horn is back to normal so she can no longer do what she did to Twilight."
Celestia asked, "Where is Trixie?"
Starlight replied, "I locked her in my old bedroom. I do not believe that it would be in our best interests if she is in here while I free Twilight."
Everypony nodded in unison as Starlight headed over to Twilight. She waved her hoof in front of Twilight's face and asked, "Twilight, are you ok? Can you hear me?"
Twilight just sat there in an unresponsive silence as though Starlight was not even there. Rainbow asked, "Starlight, why did you ask her that? You know how deep she is under Trixie's spell."
Starlight replied, "Rainbow, I had to make completely sure that she is completely under her spell. If I would have got even the slightest amount of response from her, I would have to alter the energy I will be using from this."
Fluttershy asked, "Uhm....Starlight. I know I'm no master of magic or anything but do you think your spell might work better if you took your helmet off?"
Starlight stood there annoyed for a couple of seconds but realized that with the state Twilight is in, that removing her helmet may help her succeed with this. She replied, "Good thinking Fluttershy."
She took her helmet off and began to stare intensely at Twilight. Her eyes began to shine white, she began to levitate as she recited,
"For the pony free will is a thing of the past
But this can not last
Freedom is what the pony needs
So she may see where life leads
The time has come for her to think as a whole
So that what can be fulfilled is her role."
As soon as she recited this, a powerful beam of energy shot towards Twilight. While it was absorbed into Twilight's body, a powerful shock threw Starlight back into the wall, "Oww!" Her friends gave her a concerned look as she continued, "Well I certainly wasn't expecting that."
Everypony headed over to where Twilight sat to see if it worked. She blinked her eyes, shook her head and said, "Ugh....where am I?" In front of her she saw Celestia, Spike and her friends, "Princess Celestia, Spike, girls, I'm so happy to see you."
Upon hearing this, Applejack was the first one to hug her, "We're glad to see you too sugar cube."
Twilight asked, "What happened? Why am I in bed in the middle of the day." She then felt her foal kick her, "And how in Equestria did I become pregnant?" She looked around and continued, "And where is Trixie?"
Celestia replied, "Twilight, there is a lot that we have to catch up on since Trixie put that mind control spell on you."
Twilight asked, "Mind control spell? I don't remember Trixie putting a mind control spell on me."
Celestia looked back and motioned for Starlight to step up to Twilight. When Twilight saw her she was stunned to see how much she had grown and it stunned her even more that she was an Alicorn and was wearing armor. She asked, "Starlight, is that you?"
Starlight replied, "Yes Twilight, it is me."
Twilight asked, "But-but how did you get so big? How did you become an Alicorn? Why are you wearing armor?"
They heard Twilight's stomach growl and decided that it would be best if they caught her up on everything over a meal. Starlight put her helmet back on and said, "Wow Twilight, I have never heard anypony's stomach growl so loud in my life."
Celestia added, "Let's get you down to the dining hall and get some food in your stomach, you must be hungry."
Given that Twilight had not walked much recently she was wobbly on her feet but managed to get down to the dining hall. While everypony was happy to see that she was free of Trixie's control, they also knew that there would be a lot of catching up to do, some of which they were unsure of how Twilight would react to.
