"Cannibal"

“Ugh i’m so hungry” says the unknown lifeform “time to stir up some sustenance”.

one month later

“WH-WHAT!!! WHAT DO YOU MEAN HE’S BACK!!!”

“Princess… this is no joke he has returned”.

“Send a letter”

Dear Twilight,

Some trouble has occurred in the crystal empire, again.

from what information I received today is that somepony stole the crystal heart and Sombra is coming back. We don’t how for certain but this is going to require a lot power and magic. I dont know if I can fight him by myself i need you and discord come immediately to my castle, we have 1 week before this threat reached the empire.

Sincerely Princess Celestia

What...what does she mean sombra was destroyed how can he return and why cant she face him alone. twilight thought to herself.

“SPIKE GET FLUTTERSHY WE NEED TO TALK TO DISCORD!!!!!!”

“on it!!” the little dragon said firmly.

a few hours later

“Oh fluttershy so glad to see you did u get discord”.

“Yes” fluttershy said with a slight question in her voice.

“If you’re wondering why i need to talk to discord...sombra has come back and we need his help to stop him”

Fluttershy jumped at the name.”why the use the crystal heart”.

“I-it'sbeen stolen”.

Fluttershy gasps.

“Ughwhy do i need to go” discord said in a bored voice.

“Because the princess says she needs your help” twilight breaths out in a matter of fact voice.

the next day when they get to the castle

“We must be on our way we have only six days to get the crystal empire” celestia says in a rushed voice.

“Ohh princess you forget i can just bend reality”.

“That is why we need you, we need you to get us there, you won't be able to fight sombra though he is too strong for you to not to cause damage”.

FLASH

“We’re here, can I go now”.

“Yes u can leave now”.

Discord leaves.

“We need to set up defenses whatever’s coming is big I can see it from here.” said celestia worriedly.

Princess cadence is getting her spell ready, Shining Armor is getting the guards ready and setting up his own protection spell.Twilight is trying to keep everypony calm and continually reassures them that they are going to be fine.Celestia preps herself for the upcoming battle.

meanwhile the oncoming enemy is strategizing an assault plan

King Sombra grunts.”You know this coming back from the dead thing kinda hurts.OK so it looks like they are preparing a defense.YOU THERE GET BACK IN LINE,C’MON KEEP GOING,THAT’S IT KEEP DOING THAT AND DONT FALL BEHIND!!!!”

“O sombra soon enough you will get your precious empire back,but first u must cause as much chaos as possible and even after you become king again you will continue taking orders from me…”

“What i thought this was a one time time deal!”

“No Sombra I brought you to life with my my own life force and i can easily take it back if u don’t comply like the property you are”.
