Twilight's mind was still thinking of what had happened. When she had tried to worn her mentor and brother about Cadence they lashed out at her. When Shining Armor and Celestia had left her friends and Spike went over to comfort her, telling her that it will be okay. Applejack them said she might need some alone time. She looked up to see Cadence standing above her stroking her head like a puppy.

"I'm sorry." she apologized to the pink alicorn.

Cadence merely looked at her with a smile before her eyes shifted into green slits, then turned back very quickly. Before she could assume she was seeing things Cadence said "you will be!"

Suddenly a ring of green fire circled her and created a dome. Then Cadence closed all the doors and windows, her magic was green. That made no sense, Cadence magic is blue. A flash of green light caught her attention as "Cadence" was engulfed in green fire and turned into a creature she had only read about. A changeling. She guessed it was female.

"Hello Twilight," she said.

"Who are you, and where's Cadence?" Twilight asked slightly scared because she was in her magic.

"I'm queen Chrysalis and she is in the abandon Canterlot mines." Chrysalis said smugly. "In fact why don't you join her, i'll meet you there in a bit."

Twilight then felt the scene fade out as she passed out. Chrysalis took the unconscious pony and teleported her to a cocoon in the mines.

When Twilight woke she looked around her. She was in a cocoon. Chrysalis was there smiling turned to a familiar pink alicorn held down by slime "Cadence!" she tried to shout but the slime in the cocoon made it muffled. However she was heard and Chrysalis turned to face her.

"Finally your awake, now we can get started." Chrysalis said as though she had been for hours.

"What do you want with me?" Twilight asked, fear in her voice.

Chrysalis smirked before saying. "Its quite simple Twilight, that cocoon your in will turn you into a changeling. And not just any changeling but by using a spell I will infuse with my and my mate's DNA making you my heir. I was just waiting for you to wake up."

As Chrysalis's words sank in Twilight started to thrash about the cocoon trying to escape, but all it did was amuse Chrysalis.

"Don't you dare touch her." Cadence shrieked. Chrysalis laugh.

"And what are you going to do about it?" Chrysalis asked before turning to Twilight. "And don't worry your not going to be alone, when your done and we invade i'll turn your friends into your sisters."

Cadence had a look of shock of Chrysalis's plans but Twilight asked "Why." "Because I'll need heirs now that all be ruling Equestria, It will be vary painful and long for you but it will be worth it, you'll see." Chrysalis answered.

"Chryssi are you done monologue yet, I want to get started?" Can a different voice and Chrysalis, Cadence, and Twilight looked to see three changelings, one appeared to be scarier and one foot bigger then Chrysalis.

The two smaller ones stayed where they were but the bigger one walked over next to Chrysalis. "So this is the pony you picked to be are daugther" he asked.

"Yes Aphid, her and five others. But they'll be transformed after invasion." Chrysalis said smiling.

"Why are you doing this?" Cadence asked.

"Because I need heir's, and I can't have daughters." Chrysalis said before putting a muzzle on Cadence's snout. She then turned to Twilight. "Lets get started."

Chrysalis and Aphid both charged there horns and fired at Twilight and she immediately felt a change from were they blasted her.

"There, by tomorrow we will have a daughter." Chrysalis said in a giddy tone taking off Cadence's muzzle.

"Won't ponies notice your disappearance and Twilight's." Cadence cried.

"Not likely, they didn't seem to care about her at the rehearsal except her friends, and I said disguised as you that I was going to bed, And a changeling is there pretending to be asleep in your form." Chrysalis said "So I will be staying here. Aphid can you get the army ready for tomorrow."

Aphid nodded and left knowing he could see the transformation of one of the others. Chrysalis sat down to watch.

Twilight writhed in agony, the last few hours have been tormenting. She had felt her horn lengthen and twist, her skin turn into exoskeleton, and holes develop in her legs as well as changeling instinct and ways being ingrained into her mind. The only good thing that had happened was Chrysalis had left an hour ago. She wanted it all to stop.

Twilight waited, she knew she was missing wings. A extremely painful feeling in her back told her they were coming. A muffed scream was heard in the cocoon as translucent changeling wings burst out, the slime keeping her from bleeding to death and healing the damages around her wings. As she felt more changeling ways being ingrain in her mind she saw Celestia in a different light, as a tyrant. She didn't care for the ponies or any other creature. She sent her on deadly missions. She even let her own sister suffer, then sent her to the moon for a thousand years when she couldn't take it anymore. She turned a creature to stone for being himself, and the chaos wasn't that bad. And she and her "brother" abandon her when she tried to warn them. Maybe mommy Chrysalis wasn't so bad. She actually cared. She would love and care for her and her friend/future sisters.

Chrysalis entered the mines seeing that Twilight was ready, with a slice she ripped the cocoon and aloud Twilight to slip out. Twilight then started to cough trying to get slime out of her lungs and stomach. when Twilight was done Chrysalis took a good look at Twilight. Twilight looked like a royal changeling should. But was only a bit taller then a pony foal.

"Are you feeling better darling?" Chrysalis asked.

"Yes mother." Twilight chirped. Chrysalis smiled.

"Twilight do you recognize me?" Cadence asked cautiously.

"Of course I do Cady" Twilight said cheerfully.

"Okay you come with me. Will hid you till the wedding then you'll get your sisters." Chrysalis said as she shrank Twilight, transformed into a Cadence look alike, put Twilight in her pocket, and teleported to her room.

Cadence started to sing.
