"Well that was fun" Brawl said
"Yeah I want to destroy something else" Demolisher said
"Sorry but this mission will require stealth" Shockwave said
"What mission?" Flamewar said
"Even though we destroyed their precious Crystal Empire the capital of Equestria still remains a beacon of hope in their eyes, and with Sigma Supreme bent on our deaths its time we went dark for a while"
"So?"
"So I have sent Barricade and Dead End to infiltrate the Canterlot libraries and Celestia's school for gifted unicorns and plant detpecks in key area's of the buildings, the chain reaction will lead to the destruction of the learning places of unicorns and the burning of precious magic spell scrolls"
"So why not send us to do the work? We like blowing stuff up" Brawl said
"The whole country will be on high alert after what we just did to their Empire, Barricade and Dead End are effective scouts and will ensure that the mission will be accomplished"

The Crystal Empire Train station
Twilight, Spike, Applejack, Pinkie Pie, Rarity, Rainbow Dash, Shining Armor, Cadence, Celestia, and Luna all stepped out of the train and into the snow north of Equestria, they where their to check on the status of the Crystal Empire after a huge explosion occurred in the general area.
Twilight was the first to break into a run her allies following behind her, she lead the way though the snow storm as they drew closer to the Empire
"Are we their yet?" Pinkie asked
"Almost" Shining said
"What do you think we'll find their?" Rainbow asked
"Either a protected Crystal Empire, or a bad sight" Twilight said
"Don't worry everypony I'm sure its just as how we left it" Applejack said
"I think I see it!" Spike said pointing towards the light in the distance.
That gave Twilight and the group some comfort as they once again broke into a run, Twilight closed her eyes as she neared the edge of the storm hoping that when she exited and opened her eyes she would see their beloved Empire. Finally she exited the cold storm and into the warm sunlight
"Finally where out" she said
Her friend also came out of the storm and onto the hill which hide the empire for the time being.
"So whos gonna take a look?" Spike asked
"We all go together" Twilight suggested "Okay?"
The ponies and dragon all looked at each other and nodded in agreement.
"Okay one. two three!"
The group stepped on the top of the hill and opened their eyes, they all Expected to see a glitsling Empire, but their hopes where shattered as their eyes gazed upon a burned down city in flames.

Canterlot
It was a foggy afternoon but even foal could spot a mysterious purple object floating in the sky
luckily for the con's they where able to sneak around the back without anypony noticing.
"This is as close as I can get to the castle without being spotted"
"Fine you just stay here in case we need a quick exit"
"You ready Barricade?" Dead End asked
"Ready"
"lets go"
The two Decepticons jumped out of the ship falling through the air and surprisingly landed in the Canterlot garden without drawing any attention to themselves.
"Okay lets make this quick and quiet" Barricade said
"Ha I'm the master of stealth and sneak thanks to my cloaker" Dead End said
"Yeah but that thing has a timer, while my grapple beam can be used any time"
"Sure but you will have to take the long way"
"Shockwave whats our target?" Barricade said
"Before you plant detpacks in the school and library, you will plant detpacks in the castles stained glass windows that are significant to the pony culture and history, some of which include the many accomplishments of the elements of harmony"
"Good I'm gonna enjoy this"
The two cons made their way trough the courtyard keeping a low profile the guards however where always getting in their way.
"Ugh can't we just silence them or something?"
"No we have to keep this quiet and quick" Barricade said
"So what do we do first?"
"Lets set bombs in the Canterlot archives, word is Celestia pet student Twilight enjoys reading"
"Well I hope she read all the books in here because their about to burn!"

The Crystal Empire(whats left of it)
Twilight could not believe her eyes, all of them just stood frozen in placed as they looked on to words the ruined empire, their eyes where so fixated on it that they didn't even notice a large blue omega sentinel in ship mode pass over their heads.
"What happened here?" Cadence asked with a heavy voice
Twilight turned to the group,they all had either shocked expressions, or watery eyes Rarity with the most tears.
"lets go down their and find out"
It took the group two minutes to get to the city, they looked at the deviation cussed by the explosion, everywhere they saw burned bodies, mutilated mares, and crushed colts, it was to much to bear as the kept walking
"What could have done this?" Luna said
"Yeah the destruction shows evidence of an explosion but other bodies loomed like they where attacked by somepony" Twilight said
"Or something" Celestia said
The group turned to face Celestia, the word "something" wasn't used unless their was a new type of threat on the loose
"what do you mean princess" Spike asked
"Look here"
Twilight walked over to the princess position, and she couldn't believe her eyes.
It was the Crystal Empire library, every single book, every page of priceless information she will never know was ashes.
Twilight's sorrow was replaced by pure rage, whatever did this was going to pay for this crime against books.
'I'm going to find the thing responsible for this"
'I'm not referring to the library Twilight" Celestia said
Twilight looked at her mentor
"I'm referring to her"
Celestia pointed to a dead elderly body. The librarian.
Running towards her she checked for what caused her death, then she found it, a small hole was in her head, small but it went right through her brain.
This intrigued Twilight
"What could have made a hole like that? Their is no known weapon of that function"
"What I wanna know is why wasn't the empire protected? Isn't the crystal heart suppose to protect it from danger?"
That also intrigued Twilight was happened to the heart?
"Ugh guys" A voice said
All eyes where on Rainbow who was flying.
"You might wanna come see this"
Rainbow flew in the direction of the castle, with the ponies in pursuit.
_____________________________________________________________________
The two scout Decpetiocns Dead End and Barricade where done planting the detpacks in the star swirl the bearded wing and ready to move onto the next stage of their mission, destroying the murals in the Canterlot castle.
"Okay Shockwave we have planted the bombs in the archives and now moving onto the castle murals" Barricade said
_____________________________________________________________________
When the ponies arrived at the castle, they didn't notice it before but it was not destroyed, but knocked over by something.
"What could have enough power to knock down an entire castle?" Spike asked
"I think we have a bigger problem everypony" Shining said
The ponies looked in the direction of Shining Armor to see a horrible sight.
Laying on the ground was the shattered remains of the crystal heart.
The ponies approached the remnants, when Spike tired to pick a piece up is disintegrated as soon as he touched it.
"Well that explains why the empire wasn't protected" Twilight said
"Yes, but this doesn't explain what destroyed it" Celestia said
Twilight thought for a while, what could be so powerful to infiltrate the empire, destroy the heart, and blow it sky high?
"Keep looking around" Twilight said "Maybe their something here we can find that will tell us what happened here"
__________________________________________________________________
The two bot where just done placing the bombs on the stained glass windows in the throne room.
"Ha can you believe it Barricade? These ponies think they achieved great things by using their powers of friendship"
"Yeah" Barricade said like this one, these six ponies defeated a spirit of chaos?! Wait till they meet Unicron"
"And this one, this couple defeated an army of evil creatures just by using love and lived happily ever after? If I was their I would slit their throats"
"Ha I'm glad were gonna destroy these windows"
"Okay thats the last of them, Shockwave Bridge us out of here"
"As you wish"
A ground bridge opened up in front of the two cons and they stepped through the portal with a timer set on the detpecks.
____________________________________________________________________________
Twilight and her friends where sitting in the train on their way home, did not find any evidence to the empire destruction, so they decided to give up.
"Maybe will find something later?" Twilight asked
"Maybe" Celestia said as she was dropped off
"Don't worry Twilight just continue your studies in ponyville and I will see to what happened in the Empire, and keep this between you and your friends, I don't want this to get out it might cause panic"
"Yes princess"
Then the train set off in a non stop trip to ponyville.
1 hour later
The royal guard and the Canterlot fire department where busy with a mysterious fire that had destroyed the star swirl the bearded wing and an explosion that shattered all the accomplishment murals, the exact nature of the fires was unknown but Celestia kept this to herself, she didn't want Twilight to worry.
"Celestia" Luna said
"Yes?"
"You think this fire could have something to do with the empires destruction?"
"Maybe"
