On the Island of Sodor

Thomas was exhausted, his wheels ached and his axels moaned, the fat controller had him puffing all over the island making deliveries, while he loved being really useful, his mind usually wondered off into space and beyond. The night fell quickly over the island as he finally chuffed his way towards Tidmouth sheds for a well earned rest, "I always loved running my branch line at night, So peaceful." Thomas mentioned happily to his fireman and driver. He watched as the fireflies danced through the air and the trees around him, the wonderful ballet of nature playing out before him. He stopped on the turntable and let it direct his rear end into his shed, "Thomas, we have bad news for you," James started as he cleared his funnel, Thomas grew tense as his boiler boiled. "You know of the accident that happened on the main line today, correct?" Gordon's saddened tone made little Thomas all the more upset as he began to feel very uneasy. "Yes, I'm aware of it, What's that got to-" "Percy got caught in the flames, he...he..." Emily froze to sob and Toby decided to finish for her, all the while Thomas being on the verge of tears, "Little Percy didn't make it, he was scrapped earlier this afternoon." Toby then began to cry as with Thomas and the rest of the engines. Thomas seemed to have took it the hardest as he let the tears flow, he blew his whistle loud and for as long as he could, along with the rest of the Tidmouth engines. The next morning Thomas stayed locked in his shed, too depressed to answer to anybody, not Mr. Conductor, James, Toby, Annie and Clarabelle, not even the fat controller could talk him down. Thomas haunted by visions of his best friend resting in his shed, but only the green paint was charred black in a few places, his funnel and whistle melted and his face burned with second to third degree burns. Thomas needed to get fresh air.

Meanwhile in Ponyville,

Fluttershy lied in her bed, covers wrapped tightly around her body and wings, she tossed and turned every few seconds. Her dream was a strange one, at least, She was corned by a large, brown earth pony with a large metal claw attached to his back, naturally she was completely terrified of the pony in front of her. She looked at him, his laugh was that of her nightmares. "SOMEPONY PLEASE HELP ME!" she screamed, hoping to Celestia that one of her friends had heard her. "Scream all you want, no pony can hear you!" the monster pony laughed as the claw on his back shot towards her. Fluttershy's life began to flash before her eyes as she thought that her life was about to end, when all of a sudden a dark blue blur shot into the claw, making it smash into the ground. "R-Rainbow Dash?" she quivered as she blinked and got a view of a stallion with a dark blue coat, a coal black mane and tail along with a bright yellow number one as his cutie mark. "Fluttershy, RUN!" He screamed, his voice sounding like a kind British person as he bashed into the earth pony this time, knocking him off his hooves and onto the ground. He didn't need to tell her twice, she bolted away towards Ponyville. Fluttershy awoke to find herself on her floor, blankets completely wrapped around her body like a snake. Fluttershy tried to forget the dream as she went through her day, yet as she past every corner or every building she checked over her shoulder for the monstrous earth pony.

Elsewhere in Equestria,

Discord sat in the outskirts of the Everfree forest, his urge for chaos eating away at his new reformed way of life. He NEEDED to wreak chaos but if he did Celestia and Luna would lock him away in stone, he shivered at the mere thought of being imprisoned again. "I need to release chaos, but not in Equestria...but where?" he pondered over how to find the right place for chaos. A lightbulb went off over his head, he smashed it against a tree and it spiraled and twisted until a small vortex started to become visible, the vortex on the rim was a golden yellow hue with a darker blue mix as it moved inwards. With in the hole in space and time showed the image of a tank engine, painted blue with red lining, and displays the number one. "Interesting." Discord muttered as he slithered his way inside, not knowing where he'd end up. But anywhere he could cause a little chaos was good to him.

Back on Sodor

Thomas puffed through the countryside late in the night, trying to escape the visions of Percy that seemed all round him at the sheds. "I can't stay here anymore...too many memories." he whispered as he rolled along the rails. Meanwhile over in the trees just beside the tracks, a certain draconequus was exiting a vortex in a flash of white. Discord stretched his legs and wings, "My my, what a...un-chaotic world." He said, then noticed the rails just outside of the cover of the trees. Thomas finally felt slightly at ease away from everyone and in the peace of nature, "Maybe solitude is what I need." he muttered as the draconequus began to float over to the tracks and towards Thomas. Thomas seemed shocked as his eyes fell upon Discord, "Hello there little train, I am Discord, sprit of disharmony." He seemed to be trying to intimidate the small tank engine, yet Thomas viewed it as him trying to make a new friend. "Hi Mr. Discord, I'm Thomas the tank engine." He whistled happily as Discord put his claw to his chin, trying to find out how to wreak chaos.

Discord then snapped his fingers on his paw and made a galls of chocolate milk appear out of thin air, "Wow Discord, that is really cool!" Thomas peeped as he then closed his mouth at the sight of him drinking the glass, throwing the milk and having it explode. Discord smirked as an idea struck him, "Let's see how he likes having hooves instead of wheels." He thought as he stood next to Thomas, resting his paw on his side. "So...Thomas is it? You seem to be upset-" he said as he snapped and a therapist outfit appeared on his body, "- Tell uncle Discord what the matter is." he smirked as he felt that he was gaining the blue engine's trust, "Well...My best friend, Percy, got scrapped earlier today and...I just need to find someplace to forget it all for a while." Thomas admitted sadly as Discord threw on a fake smile and looked at Thomas with false sympathy and laid his trap, "You're in luck then for I, as you can see, am not from your world. But I can bring you to my world while I stay here and...Help the inhabitants." Thomas seemed ecstatic as his eyes beamed brightly up to Discord as he opened a portal on the tracks. The vortex has a pink brim and the swirling colors seemed so warm and friendly that Thomas had to smile, He looked over to his new "Friend" who gave him a thumbs up. Thomas took a deep breath and, after being abandoned by his driver and fireman, headed right into the spinning vortex to who knows where.
