Chapter One:
Arthas Menethil was given an opportunity to go to a completely new world which needed his help. However, he made a condition that he be given all relevant information before he arrived.
So he stepped through the portal into a church filled with flowers.
There was Aerith.
"So you must be-"
Arthas drew his hammer and whacked Aerith across the sternum. There was a crack and she flew against the wall, before falling down to land on the flowers.
"You killed Aerith..." said a red-haired man. "Why would you kill Aerith?"
"She's the main problem," said Arthas. "As the only person who can access the Black Materia, every side needs her. No Aerith, no Black Materia, no Black Materia, no meteor."
"Alright but the promised land-" began the red-head, tears in his eyes.
"Metaphorical," said Arthas. "And anyone, it is totally irrelevant for the vast majority of the population. Only a small band of adventurers will benefit from the spiritual enlightenment.
"The common man isn't going to get anything. And if it's something you can mine for materia, you've got plenty of that here."
"But... but Aerith..." sobbed the man on his knees.
"She wanted to call you to help her as a bodyguard. All while she went out on an adventure with friends," said a brown-haired man with a big sword.
"No, you never get anything without sacrifice," said Arthas.
"Aerith..." said the red-haired.
"Is he alright?" asked Arthas.
"I'm pretty sure this guy is a professional hitman," said Zack. "Um... are you gonna kill us?"
"That depends," said Arthas. "Do you feel like a hero yet?"
Zack began to cry.
Arthas walked back through the portal and adjusted his hammer on his back. "Alright Muradin, the errand is done.
"Now we can get back to base."
"Wasn't that a bit much, lad?" asked the dwarf.
"Never drop the hammer when a runeblade is handy," said Arthas.
"Yeah, I guess you're right," said Muradin.
They arrived at base to a hideous surprise. "Captain," said Arthas. "Why are the guards not at their posts."
"I am the ghost of Aerith." Then the ghost of Aerith crossed her arms in a huff. "I was wrong about you, Prince Arthas."
Author's Note:
See, this is the problem of having Arthas go into any other medium.
On paper, his character is essentially a pro-religious Tidus or Vaan with a more martial bent. The problem is that Arthas is incredibly ruthless and highly competent. While also being intelligent and charismatic enough to avoid stupid evil. Since fiction by nature requires characters to act irrationally, Arthas tends to be a game breaker.
Thus this fic.
