It's been six days since the note in Luna's chambers told Celestia to come to the northern part of the Crystal Empire, and Rainbow was currently interrogating the changeling they found, and they hadn't gotten anything. "Again: why did you reveal yourself?!" Rainbow asked, a little aggravated.

The changeling just stared at her, saying nothing.

"Uh, why won't you talk!?" An idea came to Rainbow. "Okay, can you tell me what country you're from?"

"What?" The changeling asked, surprised at the question.

"'What' ain't no country I ever heard of. They speak Equish in What?"

"What?" the changeling asked, certain already something was wrong in the head with Rainbow.

"EQISH, MOTHERBUCKER! DO YOU SPEAK IT!?"

"Yes."

"Then you know what I'm saying?"

"Yes."

"Then why did you reveal yourself!"

"What?" the changeling asked, now just for shits and giggles.

"That's it!" Rainbow yelled, charging her horn. "Say 'what' again! SAY 'WHAT' AGAIN! I DARE YOU, I DOUBLE DARE YOU, SAY 'WHAT' AGAIN. SAY 'WHAT' AGAIN ONE MORE CELESTIADAMN TIME!!"

"Whoa, hold on their, Dash," Spitfire said as she grabbed Rainbow and dragged her away. "The princess said not to harm him with magic."

"What else am I supposed to do, ask nicely?"

"Actually, yes."

This got looks of surprise from both Knights. "Huh?" was all Rainbow could say.

"All you need to do is add 'please' to the end, and I might answer."

"Oh," Spitfire said. "In that case, would you please tell us who your ruler is?"

"Queen Chrysalis."

"The one who attacked Canterlot?" Rainbow asked.

"The same," the changeling said. "And by the way, all my friends call me Reflector, or just Flec."

"Okay then, 'Flec', why did you reveal yourself?"

"Because I wanted to. Simple as that."

"In that case," Rainbow said, "would you please tell us why you're here in Canterlot?"

"Of course," Flec said as one of his brothers relayed a message.

Celestia is a quarter way to the Empire. If they want to catch her, they'll have to fly.

"To deliver two messages, one of which I already delivered."

"Then would you please tell us the second," Spitfire said.

"That the most dangerous poison is the one we changelings seek.

"Love."

"Well, thanks for that," Spitfire said as she and Rainbow left the changeling's cell. "What do you think he meant, RD?"

Rainbow didn't answer, but was going over the two messages. Okay, let's see. Beware the Gem, and the most dangerous poison is love.

Gem. Love. Rainbow's eyes widened. Those were meant for Celestia. They must be using Rarity as a trap. Or worse, she's with them.

"Gotta stop her," she said as she ran to the nearest window.

"Stop who?" Spitfire said, but Rainbow didn't hear her.

Rainbow quickly made it to the nearest window, but, for some reason, when she got in the air, she wasn't able to hit rainboom speeds, so she flew at her best speed, just under half mach one, with Celestia at the same speed, but her headstart meant she would still be in the lead.

A day later

Celestia set down gently at the northern edge of the Empire, seeing not a single soul, unaware that Rainbow had followed, and was closing in.

Her coat, by itself, made it to where she blended in well with the snow, but her mane and tail counteracted that. Just as she landed, she felt something dark, but believed it to just be nerves.

After thirty minutes of waiting, having to use a warming spell, there was a flash of light, and the two mares she had been waiting for appeared.

In front was a gagged Rarity, an inhibitor ring around her horn, her white coat and purple mane and tail were disheveled, torn in some places, and her left eye was swollen shut.

Behind her, in battle armor fit for a royal, colored as black as night with accents of sliver, was Luna. "Hello, Celestia," she said coldly.

"Luna, why have you done this?" Celestia asked.

"Simply because you are a terrible ruler," she said. "And a terrible sister," she added after a second.

"Luna, we both know that isn't true."

"Then why did you not try to release me before the prophecy said I would return, or try to have the Elements cleanse me before by bringing me back? Don't bother lying, I would have still felt your summoning magic if you tried."

"I did that because I hoped you would come back as Luna, not Nightmare Moon."

"It seems you were mistaken there," she said as she saw a small, cyan speck approaching. Perfect, she thought with a smile that went unnoticed. She pushed Rarity to her. "Go, take your lover and leave, The Empire is already with us."

"Us who?" Celestia asked, lighting her horn, unaware of the seed doing so planted in her.

"Why, the Eclipse," Luna said before a single voice that wasn't supposed to be there for Celestia, but Luna welcomed, rang out.

"GET AWAY FROM HER!!" Rainbow yelled, firing a shot of magical energy that was aimed for Rarity.

It seemed to travel in slow motion for Celestia as she saw the beam lance to her lover, but she couldn't do anything, as she felt her magic draining out of her.

She saw the beam strike Rarity in the barrel, and a large scorch mark appear. Thw white unicorn fell to the ground, her eyes still.

"No," Celestia whispered. "No, no, no, no, NO!!" she yelled, her volume increasing every time as she looked at Rainbow, and felt one, small surge of energy flow through her. "I told you to stay away," she said. "Now, you will pay." She then fired a beam of dark magic at Rainbow, who saw it, dodged it, and promptly ran away.

As the beam left her horn, Celestia fell to the ground. As her vision dimmed, she thought she saw Twilight, looking much darker. "Hello again, mother," she said as her horn was lit, and Celestia's wings began to shrink, but Celestia didn't notice, until they were gone.

A few hours later

Twilight and the rest of the Eclipses, including Rarity, who had simply sent an illusion in her place, stood in the palace throne room, deciding what their next move should be.

"So, what do we do next with Celestia?" Nightmare asked.

"That's. . . a little complicated," Twilight said. "I was hoping to make her my student in dark magic, but she said no. Shouldn't be surprised, seeing as how I came up with a back up plan for it."

"Oh? What might that be, darling," Rarity asked.

"That spell field I placed? It was designed to place a seed of darkness in her heart," Twilight said. "That's why the spell she fired was dark magic, and why she got so angry so fast. All that's left is to activate it, and you might not like how, Rarity."

"Why's that?"

"Because, well, it and I'm quoting here, 'in order for the seed to be activated, the afflicted must have blood flowing much more actively, and dopamine must be enhanced'. In short, you and Celestia need to have sex."

"What?" Rarity said in disbelief.

"The spell instructions say that the one the seed is in has to make love with the one they love, and as far as Celestia knows, that's you. It's not my fault that the spell needs it. Besides, didn't you say that if we turned Celestia in anyway, you might be interested?"

"'Tis true, she did say that," Luna said, getting a glare from Rarity.

"Plus," Twilight said, "if you did so, the seed would start spreading instantly, and you'd only need to keep going until it's done, which should be indicated by Celestia's eyes going the same shade of green as mine."

"Is it really the only way," Rarity said.

"Yes, it is."

Rarity sighed. "Then wish me luck," she said as she left the room.

"Well, this is going to be interesting," Cadenece said.

"Indeed it will be, my love," Chrysalis said, as the two had started dating in the past week just after the trap had been placed.

"Well, I don't know about you girls," Amethyst said, "but I'm going to do some reading," she said, leaving the room and going to the library.

"And we'll go make sure the crystal heart is ready for the loyalty spell and is able to transmit it, Twilight," Cadence said as she and the changeling queen left side by side.

"And we," Nightmare said, Luna, Galaxy, and herself, "will make sure the sun and moon still follow their cycle."

With that, Twilight was the only one in the throne room visible. She lit her horn, and, close to the throne, Opal appeared.

"Hello, slave," Twilight said.

"Hello, my Mistress," Opal said, bowing. Ordinarily, Twilight wouldn't have any of those she put under the loyalty spell callin her this, but figured it was appropriate because of the, ahem, activities the two had done. "What do you require of me?" Opal said, still bowing.

"Nothing, simply company for now until Rarity returns, hopefully with Celestia."

"Of course, Mistress. What would you like me to do?"

Twilight said nothing, only lit her horn. "Just hold still for now." As she said this, a small stream of magic came from her horn and made contact with Opal's horn. As it faded, Opal blinked rapidly, and looked around, and, when she saw Twilight, glared.

"You," she said, venom in her voice. "Why is it now you decide to let me have my mind back? Why take it at all?"

"Because, I just wanted to talk with somepony who would give me their actual opinion rather then what they think I want to hear."

"So I'm your therapist?" I think it's a little late for that, seeing as how you killed the stallion who had a crush on you, and killed plan on brainwashing the princess." At Twilight's look, she added, "Yeah, bitch, I remember everything I heard when I was your mind slave, as well as everything else."

"Then why don't you try to run, like any pony would.

"A: I'm not an idiot. B:Not much good getting away would do me if it could, what with Celestia imprisoned. C: You could always just blast me with that spell of yours." She paused. "And, I guess, because I liked it."

"Wait, what?"

Opal shrugged. "Yeah. If I had to guess, I'd say the spell makes me like it, or I subconsciously wanted it." She bowed again. "My Mistress."

Twilight sighed. "Opal, you aren't under my control. Just Empress will do now."

Opal got up, and teleported in front of Twilight, who, to her credit, only jumped a little. "How about 'Love'," she said, bringing Twilight into a full-fledged kiss. Twilight's eyes widened to begin with, but she slowly closed them as the pleasure took over.

A few seconds later, Opal pulled out, allowing Twilight to ask, "Why?"

"I don't know," Opal replied. "But, I always did like your figure, and you new color scheme. Guess It just needed time to grow on me." She giggled. "Just how long do you think Rarity will be gone?"

"I'd guess an hour. Why?"

"This," she said, kissing Twilight again and pushing her to the floor, the alicorn offering no resistance. With Twilight on her back and Opal on top, the two stopped kissing again. "You know, if I had known this was going to happen," Opal said. "I would have asked for it in the cell."

"Why are you complaining when your getting it now," Twilight said, kissing her lover again, their tongues wrestling for domination of the other, this time holding the kiss as Twilight's hoof moved down her lovers body until it reached Opal's glistening marehood. Just the act of Twilight making contact with it made Opal moan in pleasure into Twilight's mouth.

This made Twilight begin to slowly rub her lover's pussy, causing even more moans. Not wanting to look unappreciative, Opal's hoof made it's way to her lover's marehood, and reciprocated the action, causing the lavender alicorn to moan in response.

Opal pulled out of the kiss, still rubbing her lover, and began to move downward, sating, "I always did like this part of the activities we did while I didn't have control over my body." She eventually made it to where she had a good view of her lover's sex. "And I definitely liked how you tasted," she said before she dove in, causing Twilight to shriek out in pleasure.

"Ahh, YES, OPAL! YES!" Twilight screamed. "DON'T STOP, PLEASE, DON'T BUCKING STOP!"

Opal didn't speak, only put her tongue into her lover's slit, and began to lick it like it was a one of a kind delicacy that would soon expire.

As she was, Twilight decided to give her lover the same feeling, and put a hoof on Opal's horn, and began to stroke it, causing Opal to moan into Twilight's sex.

As Twilight stroked faster and faster, a charge began to build up in Opal's horn, just as Twilight felt something in her build up. "O-OPAL, I'M ABOUT TO-AHHH!" Twilight cried out in pleasure, unable to finish her sentence.

Not a second later, a stream of marecum rushed out of her wet slit and onto her lovers face, and a jet of magic came out of Opal's horn and washed over the two of them, the magic disappeared shortly after it made contact with Twilight's coat. Opal's muzzle was wet with Twilight's fluids as she pulled out of her lover's slit and crawled back up to Twilight's face, both mares smiling.

"I love you, Opal," Twilight said, panting.

"I love you too, Twilight," Opal said, kissing her lover.

As Rarity was making her way to the cell where Celestia was being held, she decided she would stay in her nightmare from, saying that Twilight could only save her by giving her this body. "I can't believe I'm practically selling my self for this," she muttered as she reached Celestia's cell. The two guards, crystal ponies that had been enthralled by Nightmare with the loyalty spell Twilight had taught them after she returned, moved aside and let her pass, not saying a word, but they did unlock the door.

Rarity opened the door, and let out a genuine gasp at the sight of Celestia's current state.

Her coat was stained with dirt, her once beautiful etheric mane and tail now hanging limp like any normal mane and tail, and they too were stained with dirt. Her eyes were bloodshot, most likely from crying over Rarity's death. Well, her supposed death, anyway. Around the base of her horn was an inhibitor ring that prevented her from doing even the simplest spells. Where she once had wings, she had a plain barrel, a spell Twilight learned from the former alicorn's journal being the cause.

"What, come to torture me, or to kill me?" she said as she looked away from the door, not even looking at who entered.

"Now, why would I do that, Celly," Rarity asked, causing Celestia to spin around in shock.

"Rarity?" she asked in hope before she saw her lover's form. "What did they did to you," she asked, horror in her voice.

"They saved me, Celly," Rarity said.

"What do you mean?" Celestia said.

"When i was hit by that beam of magic, I was barely alive. Twilight appeared, and I suppose Luna told her of what happened. I guess she asked me something, and I responded right, and she gave me this form, saying after that it was the only way they could save me. I deided to go with it, as I knew you wouldn't be able to handle losing me," she said as she walked over to Celestia and nuzzled her, which made the now white unicorn visibly relax.

"But why did the guards let you through?"

"Well, Twilight did give me permission to visit you once per day," Rarity said as she made her face level with Celestia's. "That, and I'm allied with her," she said before pulling Celestia into a kiss, the second mare's eyes widening in surprise, but she quickly pushed Rarity away.

"Get away from me, Rarity!" she yelled.

"But Celestia," Rarity said, "you already lost, and I only allied myself with her so I could see you. If I could, I would try to get the both of us away, but she put an anti-teleportation spell over the Empire."

"But why are you here? You know that Twilight wants me dead."

"No, she doesn't, Celestia," Rarity said. "Yes, she may hate you, and she did tell me the reasons as to why, but she never explicitly said she wanted you dead. If she did, then why bring you here, when she just could have left you where you were, and let you freeze to death."

"She told you I'm her mother?"

"Yes, and, though I do not like the idea of the one I love being the mother to one of my best friends, I can look past it." Rarity giggled. "After all, you are still the most beautiful mare I've ever seen, darling."

"How? Look at me," Celestia said.

Rarity only pulled up to her and gave Celestia a small kiss. "Did I say I meant your physical looks?"

Celestia chuckled. "No, I suppose not. But still, why would you side with her?"

"Well, for one, she is still caring. In fact, there was this one mare who found out the truth, and Twilight let her join us. She is willing to do the same with you, you know?"

"Yes, but I'd have to learn dark magic, something I swore I'd never do."

"Even if it meant we never saw one another," Rarity said, looking at Celestia with sad eyes. Not pleading, just. . . sad.

"Rarity, I never want to be away from you, and if I had to choose between you and being killed or what ever it is Twilight has planned, I'd want to be with you, but I swore to myself when Luna became Nightmare Moon, I would never learn dark magic."

"Who said you had a choice," Rarity said as she tackled Celestia to the floor, partly out of lust, and partly because she just wanted t get it over with, and began to rub Celestia's marehood so fast, Celestia's moans were heard throughout the cell block.

"Rarity, what are you doing," she yelled.

"Isn't it obvious, Celly," Rarity said as she kissed Celestia. "Having fun. Don't you enjoy it?"

Whatever Celestia was about to say, it was interrupted by another moan as Rarity pushed her hoof into Celestia. "AHHH, YES, Rarity, don't stop, please!"

"I knew you wanted it," Rarity said, rubbing faster.

"I don't want it, I need it," Celestia growled, pulling Rarity into a deep kiss, neither noticing the whites of the former alicorn's eyes beginning to turn green.

"I want to eat you out, Rarity," Celestia said as Rarity pulled out of the kiss.

Rarity smiled and got up, and sat down, facing the door, and said, "Then what's stopping you?"

Celestia let a devious smile loose, her whites slowly becoming greener, and laid down behind Rarity, getting an eyeful of her marehood, before diving in, causing Rarity to gasp. "Oh, yes," she said in a sigh. "Yesss, faster, Celestia."

Celestia complied, causing Rarity to moan loudly and in shorter intervals.

After nearly ten minutes of this, Rarity screamed in pleasure, "OH, CELLY, I'M ABOUT TO CUM!!"

"Then let me drink it down like the dirty whorse I am, Rarity," Celestia said, the whites of her eyes now entirely green.

Rarity said nothing, only shriek as she released jets of marecum onto Celestia's face. "AHHHH! AHHHH! Ahh." she said as she came down and Celestia moved next to her.

"I love you, Rarity," Celestia said.

"I love you too, Celly," Rarity said, with genuine love behind it.

After a minute of panting. "You know, I think just being with you is worth taking Twilight up on her offer to teach me dark magic," Celestia said, getting up on wobbly legs.

"Then why keep her waiting," Rarity said, getting up with Celestia, and the two left the cell and made their way to the throne room.

Twilight sat on her throne, Opal sitting next to her, and smiled slightly when she saw Rarity and Celestia walk in, side by side. "So, mother," she said to Celestia, "have you decided to take up my offer?"

"Of course," Celestia said, bowing, "my Empress."
