"Nothing..." Twilight said leaning back in a wooden chair. "Out of every book here, every book that could have helped, there was nothing. I really am stuck like this..."

As she stared at the numerous tomes splayed out across the table, the candle's flame flickered. She didn't even bother looking to see who was there, she didn't want to know. But all she heard was the light breathing of a changeling.

"Twilight?"

She froze, turning slowly she saw Chrysalis. She was staring at her, with an almost caring expression. Leaning to the side she saw the books, casting her eyes to the floor she cleared her throat.

"I'm here personally to bring you somewhere private so we may begin. Please, if you will, follow me." She said.

"Why private?" Twilight asked.

"So we are not disturbed by a drone. In order to receive the full training, we need absolute silence and privacy. Now follow me, I will not have us pass through the walls. I was told that you-"

"By Alfred?"

Chrysalis stopped, she looked at Twilight with a strange expression before a small smile graced her lips.

"Yes, Alfred," she smiled. "I must thank you for that. I have never seen him so ecstatic before. All he told me was he had made a friend, and received a name. I would have thought you would have threatened him for coming near you. You are very surprising sometimes."

"I'm saving my deserved anger for the one who deserves it," Twilight said glaring at the changeling queen. "You."

Chrysalis merely laughed before she began to walk away. Twilight pushed in her chair and followed.

They exited the large archives, Twilight wincing as the doors were slammed shut behind them. They walked through the glowing halls, Twilight making sure not to get to close to the walls while Chrysalis stared sadly at them.

They began going uphill, the smooth ground quickly became a stony stairwell that Twilight hadn't noticed until she almost tripped. Chrysalis stopped and looked back, but just momentarily to see if the new queen needed any assistance. Seeing she didn't, she began forward again.

The hall quickly became smaller, that even Chrysalis had to hunch her head slightly. Twilight walked on, careful not to bump into her.

The air changed as well; it went from the dank, moist smell of the dirt hallways, to a smell resembling decay and large amounts of Carbon Dioxide. Going further up, the smell intensified but she could still breath just as well.

As they drew upward even more, Chrysalis stopped and lit her horn. Fearing she'd see the gel changelings she had inadvertently made, Twilight looked away.

"Twilight, do not worry yourself, we are not going through any walls. But we have to walk across this one, seeing how the stairwell has been worn away." Chrysalis said. "There is nothing to fear. That is, unless you've forgotten how to climb walls this early?"

Twilight looked back and saw the changeling queen's horn casting a green light to the other end of the stairwell. She ignited her own horn and looked forward and gasped mentally.

The stairwell they had been traveling on, wasn't worn away, it was nearly destroyed to the base. Jagged grooves had been the only thing left above, while at the bottom it was a pile of boulders and stones with sharp points staring back at her. She looked over at the wall and gulped.

"Do not worry yourself over the walls here, they are made of stone just as the stairs are." Chrysalis said from the other side. "You have my word."

With a snort, she put her fore-hooves onto the wall and pulled forward.

She gave a small yelp as her hooves slid momentarily before her back hooves latched onto the stone surface. Panting from the shock, she righted herself and stood, side-ways, defying gravity.

She nervously put a hoof out and waited a second to begin her death fall, when nothing happened, she completed her first step. Relaxing, she took another, and then another. Smiling slightly, she did a full circle before getting brave and rearing up. Standing on the wall, she felt lighter, calmer.

"Twilight, I know it must be exciting for a once-unicorn to be standing on a wall, but please try and hurry up."

Twilight huffed before going to the other end of the stairwell where Chrysalis was waiting. Once her hoof touched the stone, Chrysalis began going again.

Twilight quickly caught up and after a minute more of ascending, it leveled out and she found herself in a long hallway with windows closely built to the ceiling.

The hall's floor was made of Olivine, black changeling's had been put into the green mass of the volcanic mineral. The light coming in from outside casted a dim orange glow across the floor, giving the figures carapace, Chrysalis, and herself a dingy hue.

The only sound were the faint shrieking of a wind outside brushing across the walls, or the hoof falls of the two changelings. As they neared the end of the hall, Twilight could make out a set of black doors ahead, before she could get any closer, Chrysalis put a wing out.

"I am afraid it would be unwise for you to see the outside." She said sadly. "There is a reason why the drones and I wish to stay underground. We are all scared by what we had done to the land."

"You mean what you forced them to do?" Twilight sneered making the changeling queen turn sharply and glare.

"I did nothing! It was Celestia and Luna who did this!" She yelled. "It was their fault my kingdom, and my subjects were forced to go underground!"

"No! I know what happened, the little history book I got told me all about it. You and your husband were going to see the princesses, during that time, a servant of Celestia killed your husband. After that, you, and only you, poisoned your own land, you did it because you felt the need to have vengeance over something nopony had planned on!"

"H-How did you know my husband was murdered?" Chrysalis asked. "What history book? I never sent, or had one sent to you. I gave strict orders to the drones to only observe, but never interact unless necessary. And I made sure that part was erased from the history books here. How is it you became aware of such knowledge?"

"Please, I may not have found anything here, but I know it was you who sent me that book."

"I told you, I had no book sent to you." Chrysalis said. "It hurt enough then when it happened, so why would I share it with another? One that I hate?"

"I don't know, but I don't care either." Twilight said. "You may be royalty to the changelings, but to me, all I see is a broken, pathetic little waste of air, who killed her nation, doomed her race, and has resorted to scarring ponies physically and mentally anyway she can!"

Chrysalis merely stared at Twilight, her mouth hung loosely. Chrysalis tried to form words, any word but all she could do was stare with her mouth opening and closing. Twilight continued to glare at the changeling queen, looking away she sat on the floor. Chrysalis continued to stare, keeping her mouth shut she ignited her horn and they both disappeared in a flash.

They reappeared, Twilight still sitting with her back turned to Chrysalis.

The room was large, dome shaped with green, fleshy walls, black supports sprouted from the floor alongside the walls. The floor was a solid stone, Twilight leaned forward staring at her own glossy reflection.

"Obsidian floors, walls, and Olivine floors back in the hallway. Were the stone steps Basalt?" Twilight asked.

"Yes. Yes they all were." Chrysalis said without emotion. "Why do you ask?"

"Because," Chrysalis could see the side of her face curve up. "I know exactly where we are."

"I'm sure you do, but what good would that bring?"

"You said I could leave at any time, correct? Any time of my choosing, and I would be free to leave without hesitation?"

"Correct. Where is this going?"

"If I were to leave, then I could easily tell both princesses that the changeling hive is exactly in the long extinct dragon pits of Nuveral. I could ask Celestia to send her sun straight down here, or have Luna flood your land with ice. Or, maybe, have the guards kill. Every. Last. Changeling." She said letting the least three words click off her tongue lightly.

"And I suppose you want that?" Chrysalis sighed. "I am not sure Celestia or Luna would agree to such things. But I do not have very good relations to Celestia, and in turn, to Luna either. Do you wish to leave?"

"No." Twilight breathed in before audibly exhaling. "I'd rather kill you myself. You ruined my life, so I take yours. To put the wounded down, as the griffons say." She said turning around.

Chrysalis took a step back, staring into the the eyes of the crazed looking changeling. Startled by the sudden look, she had heard of Twilight when she had entered into a similar state. She scoffed at that, but this look sent something she hadn't felt in years going down her spine.

Fear.

Twilight's mane was split in some parts, giving it a thorn coated look, her pupils shrunk but the whites were even brighter than before, and she was smiling. Not an erratic smile, but a small, fanged smile that sent a cold wind across Chrysalis.

"Shall we begin, Chrysalis?" Twilight said sweetly. "Or, is there something wrong? You look troubled, almost... Afraid." She chuckled before stopping and giving the taller changeling a flat stare. "Or, I could simply use a paralysis spell while you are, right now, frozen with fear, and then simply end you here. That is of course, if you would like to still teach me?"

"O-of course." Chrysalis said feeling her own breath become cold. "We shall s-start with mimicking inanimate objects."

"Well, I'm waiting, O so patiently." Twilight said standing on all fours now. "After all, I'm just here to learn. And your here to teach me how to kill you."

"R-Right... Of course." Chrysalis said backing away.

As she went away, Twilight's mood shifted and her mane became smooth again. Blinking she caught a faint smell in the air, one that wasn't there before. It made her shiver, it made her afraid, it made her fell empty and cold on the inside.

"Who knew pheromones could affect grown changelings." Twilight said under her breath. "If that was what that was."

She jumped slightly, seeing Chrysalis roll out a wooden wheel, a barrel, and then take out a ponyquin. Setting them in front of Twilight, she looked back at the unicorn turned changeling without as much fear. Smiling she put a holed hoof to the wheel.

"Now, first off we will be practicing how to turn into a simple object, such as this wheel. Now, it that same basic principle that-"

Twilight was enveloped in a flash of lavender flames, in her place sat an exact replica of the wooden wheel Chrysalis had. She rolled forward, and then back before twirling and breaking the disguise. Smiling at Chrysalis, the queen rolled her eyes.

"Now, Let's try something harder. Try and imitate this barrel, since it is a hollow object you will need to, in a sense, put a hole through yourself."

Twilight looked down at her hooves, legs and even her wings.

"No. Not any of those, you need the ones on you legs to breath in water or the walls here. Now, just imagine a hole forming in your back, let your magic wash over yourself and then, instinct will take care of the rest."

"You want me to tear a hole in myself? On purpose?" Twilight asked defensively.

"It will do no physical damage," Chrysalis said. "Remember, it is only the magic making yourself appear to be splitting. Think of it as a light passes through a prism."

Apprehensively, finding no lies in the changelings words, Twilight stared at the barrel, concentrating on her magic she envisioned herself becoming it.

Slowly, she felt her magic begin to puddle at her hooves before crawling up her legs. She felt it go up, bending her form and molding it like a putty, it made her back bend and slowly split like an amoeba. When she felt that happen, a new feeling overtook her and suddenly her magic was put into overdrive, ending the process in seconds.

"Very good, I see why Celestia chose you as her protege." Chrysalis smiled. "Now, as for the ponyquin, it is almost exactly the same as mimicking a pony, changeling, griffon or any other small creature. Except, it has no features, nothing to tell if it is male or female. A challenge, yet, it is not a challenge. Now, do not worry yourself if you cannot do it, it has no real purpose really."

Twilight changed back shortly, checking her back she saw no hole. Just a plain back with two insectoid wings. Twilight looked back at the queen and then ponyquin. Concentrating, she copied the ponyquin's features, which she found she couldn't.

Slowly, she went back and retraced her steps.

It has no features, it has no color, it has nothing but a shape. She thought. So, if it has nothing, then I just need to make an equine shape with no visible features. She grinned physically, Chrysalis also grinned seeing her figuring it out.

"Very good," Chrysalis said watching her become surrounded by lavender flames. "Very good indeed, not many changelings, myself included, can do that. Tell me, how did you figure it out?"

"All I did, was make a blank equine shape. All I had to see was white, and make it into a shape of my choosing." The fake ponyquin spoke. "Now what?" Twilight asked letting the disguise fall. "Because that had to be only minutes long, there must be more to teach?"

"There is," Chrysalis smiled. "Much more to teach, my rental pupil."

"I'm not a rental."
