Twilight/Frisk and Pinkie/Betty were leading the charge as Princess Cadence and Shining Armour were in the middle. Rainbow was in the air above them with Fluttershy and Rarity flanking them, Applejack was at the back.

Twilight/Frisk frowned “So what now?”

Cadence frowned “Well we need to find a way to help the Crystal Ponies, they all look all so downtrodden.”

Pinkie/Betty looked around “We should ask the local populace about what’s going on, they may know something.”

Shining Armour nodded “Cadence and I will start mapping out the castle. Twilight can I trust you and you friends to speak discover what happened.”

Twilight/Frisk nodded “You can count on us.”

Shining smiled at her “Thanks Twilight.”

Twilight/Frisk rejoined the other while Cadence and Shining Amour entered the castle. Pinkie/Betty smiled “I informed them of what we’re doing. Let’s go to somepony’s house and ask.”

Twilight/Frisk approached a crystal pony “I know a lot has happened, the Crystal Empire has been gone for one thousand years. We were hoping you could give us some idea on how the empire runs.”

The crystal pony shook her head “I’m sorry, I don’t remember much. I really want to help you but I don’t remember much before King Sombra came to rule us and I know don’t want to think about what he did to us.”

Pinkie/Betty gave her a hug “Don’t worry, we made sure he won’t harm anypony ever again. I promise you are safe from his wrath.”

The crystal pony smiled “My name is Autumn Gem, I will try to think of something.”

The two returned to the group, Rainbow growled “Not a singly pony knew anything, why couldn’t this be simple?”

Applejack nodded “Well somepony mentioned a Library, that may help.”

Twilight/Frisk gasped picking up Applejack and shaking her“A library, where?!”

Pinkie/Betty facepalmed “Twilight, she can’t tell you when you’re shaking her like a doll.”

Twilight blushed “Oops, sorry Applejack.”

Applejack smiled “It’s fine, now let’s get to that library.”

Rainbow groaned “Urghh.” The group ignored her as they headed towards the local library, they arrived in front of a three story crystal building.

The group entered it to see an elderly crystal pony, Twilight/Frisk frowned “We are looking for a book on the history of the Crystal Empire.”

The elderly mare slumped “I honestly don’t actually remember where any of the books are, I’m not even sure I work here.”

Pinkie/Betty smiled “Don’t worry, we’ll find it one way or the other.” The whole group spread throughout the Library, Pinkie/Betty and Twilight/Frisk frowned as they methodically looked through books. Rarity, Fluttershy and Applejack were looking trying to find the history section, Rainbow was just wandering through the Library aimlessly.

Pinkie/Betty frowned as she grabbed a book labelled history of the Crystal Empire “I found something.”

Twilight/Frisk blinked “History of the Crystal Empire, that does sound promising.” The pair quickly read through the book until they arrived at the last page, Twilight/Frisk turned the other four members of the group “It seems we have to set up the Crystal Faire, they had a jousting tournament,a petting zoo, flag of multiple hues, sweets made of Crystal Berries, a Crystal Flugelhorn as well as an anthem and finally a Crystal Heart.”

Pinkie/Betty frowned “I don’t think it means a Crystal Heart, I believe this is supposed to spread love throughout the land. This means it an actual specific artefact and we need to locate it, probably King Sombra hid it somewhere. Also there is a page missing, probably taken out by Sombra.”

Twilight/Frisk nodded “Aright I’m going to find the Crystal Heart, it must be located somewhere in the castle.”

Pinkie/Betty frowned “I’m coming with you, it would be unwise for you to go alone.”

Twilight/Frisk nodded “Very well” she turned Rainbow Dash, Rarity, Fluttershy and Applejack “can you set up the Crystal Faire while we search for the Crystal Heart.”

Applejack nodded “Of course.”

Rainbow grinned “I’m going to love the jousting, let’s do it.”

Rarity smiled “I’ll set the flag up.”

Fluttershy smiled ‘The petting zoo will be mine to attend.”

Pinkie/Betty smiled “Good luck, and be careful. Don’t want anypony getting hurt.” The two head towards the castle, they enter through the glowing crystal hallways heading towards the throne room. The find Cadence sitting on the throne with Shining Armour, Shining Armour gallops forwards “Have you found anything?”

Twilight/Frisk nodded “We are setting up the Crystal Faire but we need to find the Crystal Heart it has to be hidden somewhere in the castle by King Sombra.”

Pinkie/Betty frowned “I believe dark magic is required to open the path, it may even be in this room.”

Twilight/Frisk nodded as she returned to her unicorn form for a moment, her horn glowed with dark magic revealing a staircase spiralling downward. Twilight then resumed her human form. Shining Armour frowned “I’m coming with!”

Pinkie/Betty shook her head “No, we can handle this on our own besides you are needed to reassure the masses and helping Rainbow with the jousting. Even Sombra couldn’t even beat me at full power, I will lead if it makes you feel any better.”

Shining Amour grimaced “You better keep her safe!”

Cadence frowned “I know he is being a bit gruff but he is concerned for Twilight’s well-being and doesn't want her hurt.”

Pinkie/Betty smiled “I understand.” The two humanoids turned ponies from another world ran down the stair at blistering speeds quickly arriving at the bottom.

Twilight smiled “Thanks Betty, I must admit you’re a really good friend. Wow that feels weird to say considering our history.”

Pinkie/Betty giggled “No problem, we have had a long and twisted one” then she frowned at a close door “that door is filled with dark magic, I’ll break into the room.” Pinkie/Betty’s eyes widened as she was up against a wall, her eyes widened as she saw a man with red eyes and brown medium-length hair in grey armour as well as a woman with orange hair wearing an orange T-shirt and an orange skirt carrying a spear.

Pinkie/Betty looked at the man “Copper” then at the woman “Agate, aren’t you both supposed to be dead.” She then screamed her hair turning gully pink as Agate shoved a spear into her chest, she felt a pair of hands shake her.

She looked up to see Twilight/Frisk’s red eyes filled with worry “Are you okay?”

Pinkie/Betty frowned some of the pink vanished revealing the original brown “Yes but those weren’t memories.. I have seen seen from Agate’s perspective but I saw it from…” she screamed as pain wracked her body.

Internally however something very different was happening, something impossible in the old world. Tiny broken pieces of a soul were being connected together by Equestrian magic, soon it had formed a small empty soul in the middle of the pink soul. It then started to glow half of it filling with green and the other half filling with blue, memories of days with Copper and Agate filled her mind. While the ends remained pink, the brown part of her hair turned to a blue with a tinge of grey.

Twilight/Frisk while all this was happening had just placed a hand on Pinkie/Betty until the screams stopped and Pinkie/Betty sat up. Twilight/Frisk with a fearful look asked “Betty, are you alright?”

Pinkie/Betty smiled her eyes now showing a slight tint of green amongst the pink “I’m fine but I’m not Bête Noire anymore, I am Amber Lightvale”

Twilight/Frisk frowned “Alright but should we continue, you looked hurt.”

Pinkie/Amber smiled “I’m fine, in fact I’ve never been better. I am no longer my sister, Agate’s puppet. It seem Equestrian magic can do what soul and monster magic cannot, revive a dead soul.”

Twilight/Frisk blinked “Amazing, maybe with some experiments I can..”

Pinkie/Amber scowled “No, my soul is not a test subject. I have just been restored to a true living thing and not just some spell!” She took a deep breath “I’m sorry but you I am going to be very blunt with others. My true soul is a two-traited soul of Kindness and Integrity so I will tell the truth but will try to be nice about it.”

Twilight/Frisk nodded “I understand, just sometimes I forget about things in my search for knowledge.”

Pinkie/Amber smiled “It happens even to the best of us, now come on let’s go.” The pair ran through the room, then up some spiral stairs. The Crystal Heart was hovering there, both of them grabbed the only for dark crystals to surround them.

Twilight/Frisk fired red attacks at it only for them to do little “Arghh how are we supposed to escape!”

Pinkie/Amber smiled “It’s quite simple these objects are powered by hatred” her hand glows with green light as she fired out a green wave shattering them “the kindness trait is very effective at destroying anything using hate.”

Twilight/Frisk smiled “Well let’s get the Crystal Heart back to Cadence.” About an hour later Celestia and Luna saw the power of the Crystal Heart echo across Equestria.

Meanwhile in at the edge of Equestria a dark blue pegasus with orange eyes boarded a train. Once on her own she transformed into an orange haired woman wearing an orange T-shirt and orange skirt, she grinned “I’m coming for you, Determination.”
