The Other Side Of Us

chapter 1:an outrage in equestria

Magma spirit trots down to the train waiting for a friend of hers.
As she waits, an alicorn, thunder strike, joins along on waiting his friend.
An awkward silence goes above them wile the waiting continues. Thunder, trying to avoid more of the awkwardness, takes out his headphones and hears music, ignoring the world and entering in his world.  Magma sighs and just taps quietly as she waits.
Few minutes later, a train stops and ponies start to come out. Thunder took off his headphones and smiled patiently, waiting for his friend to come out.
"Magma?" A voice from the train got her attention. A changeling came out. Once his eyes contacted hers, he greeted her, trotting towards her.
This friend was slash silver wings.
A changeling who isn't like the others.
"Slash, how are you?" Magma asked with a soft smile on her mouth.
"Tired, but mostly great" he responded with a yawn at the end.
"I'll meet you at my house" magma said. As soon as she spoke slash disappeared in a flash.
As she was about to leave a loud crash near twilight's castle was heard.
Thunder frowned and teleported near the castle. Magma curious followed.
Once she got their she saw nothing but dust blinding her pink eyes.
Dust vanished a moment later and a mysterious hole was on the ground.
Thunder asked"how did this hole appeared?". 
"Obviously, something crashed here" a pony, named cosmic Aurora, answered. Thunder growled quietly and then stopped.
A few other ponies galloped every where with terror.
"Hey you!" Magma shouted to a mare named blue wolf. "What happened!?!" She spoke.
Blue wolf just stared at magma with widen eyes and then continued roaming around the streets of ponyville screaming.
"No luck" a pony with deer horns responded with a sigh. "We should check if princess twilight is OK" the pony, Hornzz, suggested.
"Come on" cosmic agreed and all of them entered the shiny crystal castle.
Slash appeared in front of a door of the inside.
"Let's separate so it can be faster to find the princess" slash decided. As everyone took one step they all appeared in canterlot castle. They saw two more ponies in front of them.
"Thy sister, these are the whom you say are chosen?" Luna's soft voice asked Celestia who stared at each pony standing in front of her eyes.
"Yes, Luna" she answered.
"May I ask something, your Majesty?" A brown cocoa pony named, silly Lily asked. Celestia nodded. "Where are we and what do you mean chosen? Where are we going? What are you going to do to us?" Her mouthful questions popped out real quick.
"I promise I will explain, but not here my dear" Celestia giggled quietly. "Follow me" she commanded. Hornzz, thunder, slash, magma, Lily, discord Galaxy, and cosmic followed.
The princess of the sun opened a door and inside was a broken window. The room was dark with a little of light.
"Whoa...." Galaxy whispered.
"My little ponies, the crash that happened in ponyville was an earth pony from another dimension" she explained.
"What!!!!" All seven froze for at least two seconds.
"Indeed it is surprising. I used a spell that picked the chosen ponies for this mission. It revealed all of you seven.
It is your job to bring the pony from our world. If you not complete this mission, the whole universe will be unbalanced and soon destroyed."
