Luke fell to the ground in pure astonishment. Not only was he the one who would ultimately defeat a deep lurking evil, he was also this deep lurking evil. He tried to stand up again but his tembling knees caused him to collapse once more. The ponies tried to keep their distance.
"luke wot is this y r u gonna kill us!" asked spike
Luke had to think to himself for a moment. He said nothing. He managed to stand up at last and kicked some of the sand from the desert, then turned to the ponies.
"i dunno" he said.
Then, a blinding light filled the skies and a mighty figure flew down to the ground before Luke. It was Princess Celestia. She turned to the ponies and focused her horn on them. Using her magic, she transported them back to Ponyville.
"luke u gota exercise the demon in u" she said.
"wot demon?" luke asked
Celestia then told Luke how it was not truly him that was evil, but a spirit living inside of him. How it got there exactly, neither of them knew.
"y did u send the others back" luke asked
"they think ur evil nd we cant let them stop u release the evil in u" she said back.
Celestia then sighed and used her magic to levitate the letter which Spike had dropped when he teleported.
"theres someting i miscal- misskal- did wrong" she said
"wot!" said luke
"u r not the chrono core x aka The Purification Weapon" she expl- ekspl- said.
Luke learned that 'The Purification Weapon' was the true name of the 'chrono core x', and that it was not him, but truly a weapon of mass power.
"wen i gave the elemtns of harmony a new form i used there power to mak the weapon" she said "this weapon wood destroy an evil i predickted years ago"
"do i has to killed myself!" luke shouted a question
"dunno" celestia replyed.
Luke looked towards the sun and shielded his eyes from its glaring light.
"were is The Purification Weapon?" he asked
"in the castle in canterlot" celestia said "but u cant just go in not even with my permishun you need to go to the grand galloping gala"
She explained to Luke a detailed plan of how he would arrive to the Gala and whilst there, make his way to Celestia and recieve a map of the grounds and magic spells to use on the guards. Apparently this was all too important and risky for Celestia to do herself, she could not just simply retrieve The Purification Weapon. It had magical shields that only Luke, the most powerful being in Equestria, could overcome.
"but i ent a alicorn anymore im a human" he said
"i can use a spell to change you back" said celestia and she did and teleported them back to ponyville but luke was under diskies.
***
Later that night, Luke remembered something very important from his first visit to Ponyville. He went to his room in his house and looked through his wardrobe.
"lol found it" he smiled looking at the tux rarity made him in chapter 1.
Struggling to put it on with horse-like features, it took him a long time to correctly wear the tuxedo, but he managed to put it on correctly eventually. He walked outside into the cold night air to wait for his carriage to the Gala. Ponies walked by but none recognised him; it seemed that Celestia's disguise spell was working well.
Eventually, a cart pulled by two white stallions stopped at Luke's door and he climbed on board and suddenly gasped at who he saw.
"luna wot u doin here?" he asked.
"im ur date 2 the gala" she giggled.
"k" said luke and they went to the gala.
***
After an hour or so, the two arrived at Canterlot Castle and waited for the doors to open. They watched in awe as the Wonderbolts performed amazing somersaults and tricks to open the Gala.
"rainbow dash wonts to be them" luke said
"yeah i no but they wont let her" said luna
"y!" asked luke
"we cold all die soon" she said with a tear.
Luke had to ponder for a second as to what exactly she meant, but he decided to ignore it and focus on his main mission; to retrieve The Purification Weapon. At last the gates opened and ponies flooded in, all wearing dresses and suits to mark the occasion. Luke and Luna trotted through slowly and immediatley found a room where they would be safe and nopony would find them.
"k now i need to make u seethru" said luna using magic on luke and he was gone.
"thanks" luke said "now i need to find The Purification Weapon"
Luke quickly galloped off, however Luna was not sure which direction he went as her spell had turned him invisible. Carefully avoiding bumping into ponies when entering huge crowds, Luke had to find his way to the basement of the castle before Luna's spell wore off.
Luke stealthily opened another door when nopony was watching. The door led to a small cloakroom with a hatch in the floor, which Luke opened with his magic. He stepped through, expecting stairs, but fell and landed on the ground with a hard thud and the invisiblity spell wore off.
"oops" he said.
He identified this as the basement and directly ahead of him was a large opaque white case attached to the cold, mossy stone wall.
"fond it" luke smiled.
He slowly approached the case and reached his hoof out to open it, but as he did so, a crackle of electricity made contact with his hoof and exploded in the air, sending him flying backwards into another wall.
"ouch that was mean" he grumbuld.
"indeed" said another voice
"o celestia hi" said luke to the alicorn
Celestia had entered the basement just as Luke tried to open the case. She laughed.
"luke thow needeth to use thine spelleth i taght thow" she sed
"o i forgot!" he said
Luke closed his eyes and relaxed. His horn began to glow a blue aura circled his horn and also on the case. It shone brightly in the blue colour and slowly opened to reveal another orb of light which flew out anfd covered Luke. Luke, in the light, levitated upwards. Celestia watched in amazement as the light faded, still leaving Luke in midair, and slowly transformed into a bright silver armor which slivered up Luke's hooves and twisted around his torse then up his neck and over the top of his head. Around his neck, a light green gem formed and was supported by more silver armor.
Then Celestia began to laugh maniacally and out of her usual context.
"r u ok" asked lukee lowering down
"im more than okayeth, foal!" she replyed evily
"what did u call me!" luke gasped
"a foal ur a foal im not celestia and now u opened the case witch previously sealed my power" she expl-eks-sorry this bit is too scary i cant spell very well my heart is racing.
"then who are you!" luke asked
'Celestia' laughed once more and walked over to the open case. Its white leather turned a dark black and a purple mist oozed out. A green light slowly travelled from Celestia's hooves, which turned black and had holes in them. Eventually she was fully transformed and revealed herself.
"i am queen crystalist" she said
"i dunno who u r but y r u here!" luke asked
"to get my powers back!" she announced
Then the purple mist lowered to the ground and grew, taking the form of a smaller creature. A changeling.
"wot r those" luke asked scarededly.
"my changeling army they can transform into anything or anyone" chrystalist laughed.
Luke watched in horror as more and more changelings formed from the purple mist. He then tensed himself and looked down at the gem on his chest.
"The Purification Weapon" he gasped.
"no dont use it itll kill me!" chrystalist begged
"good! PURIFICATION WEAPON ACTIVATE!" luke shouted.
The gem shone a bright green. Chrysalis covered her eyed and screamed. The Purification Weapon was in effect.
"a one time use to end the evil" luke grined.
The light then started to take a shape. The shape of an alicorn. Luke gasped as it became real and Chrysalis stared seeing she was in no danger. The alicorn stood on the floor. She was a glorious white with long flowing green hair. She wore a golden wreath around her head and had an expression so serious that it would give anypony goosebumps. She was no taller than Luke or Twilight Sparkle, but just as magnificent.
"who r u" luke asked in amazment.
"I am MUTTV," she proclaimed, "or as you may know me, The Purification Weapon."
