Hero

The morning after getting to Ponyville was like a normal morning except the fact that you were on a different planet. You were greeted with the smell of eggs and hash browns. As you hopped of off the couch you ran past your sword propped up in a corner and stopped in your tracks, you examined the huge blade and saw that there was still some blood from the changeling you killed yesterday on the sword. Then you thought of the damage that thing could have done to Rainbow Dash if you were any slower in killing it.
But you didn't want to dwell upon that now, there was breakfast to be eaten.

"Good morning." Twilight sleepily greeted as she was flipping a pancake.

"Good morning to you too."

"We might wanna eat up so we don't have to go see Celestia on an empty stomach."

"Sounds right."

"By the way what was that thing you said was better than an arrow on you planet?"

"Oh you mean by gun? Why'd you ask?"

"Here." she says as she teleports something next to your right hand.
You look down to see a 50.caliber desert eagle on the table.

"Holy shit!" You say as you pick it up.

"Language."

"Sorry. I just can't believe you made this though."

"And why is that?" she says handing you your plate.

"These things are good for war."

"I know but ponies don't exactly have fingers."

"Oh..."

"Anyway we should hurry up and so we can get ready for the guard."

"Yep." You responded with a mouthful of hash browns. After you finished eating your food you put on the clothes that Rarity had made for you. It was a pair of black jeans and a white t-shirt.

"Oh my God I love this smooth this shirt is." You made your way down the stairs and grabbed your sword, turning it on.
"How did my machete turn into this?"

"I don't know."

"Oh my bad Twilight, I didn't know you were there."

"It's fine."

"Anyway where's that guard?"

"I have no clue."

You were turning your sword on and off when a knock came through on the door.

"Princess Twilight? Are you there?" A rough voice came through the door.

"Yes I'm on my way out now." You opened the door for Twilight and the guard's jaw dropped at the sight of you. You paid him no mind as you stepped into the chariot.

"How long is this going to take?!" You yell over the loud wind

"About 40 minutes."

"Well that's nice!" You say sarcastically.

"Oh cheer up, it'll be worth the wait when see Canterlot."

"Whatever." Soon you had arrived at your destination. "So this Canterlot?"

"Yes, isn't amazing."

"Yeah it's pretty nice." The guard escorted you two to the castle doors, when you had made it over to the 2 guards watching the gate they let Twilight in but blocked you with their spears.

"Halt freakish creature, return back from where you came."

"Why I outta-" but before you could finish the sentence the glow of your sword intensified and the faces of the handle began to actually scream before it died off into a ghostly wail. The gaurds were so scared that they dropped the spears out of fear.

"Calm down gaurds, he means no hard to you." You walked past the now shaking guards.

"Thanks Twilight."

"What was that? Why and how did your sword do that?"

"I don't know?"

"Well try not to make it do that." You nodded your head in confirmation. Once you saw Celestia and Luna, you stopped in your tracks. Celestia caught a glimpse of you and made her way down the stairs.

"So this is the "human" you were telling me about?"

"That's right." Celestia walked over to you and examined you and your sword.

"May I see your sword?"

"Sure." You put the sword down and then Celestia attempted to pick it up with her magic but it simply fell with a resounding clang.

"Hmm this sword may be immune to magic. Perhaps it requires to be held physically." She then knelt her neck down to grasp the sword but it simply fell again she tried with 2 hooves, she tried and again but the sword just kept falling as if she was trying to pick up an actual planet. On her 7th try, the sword's faces began to glow.

"It seems were getting somewhere." But this didn't mean what she thought it meant, as the sword forced itself out of her grasp and flew over to you setting itself down into the ground. The other 5 ponies had finally arrived and made their way to the 3 of you. Then out of everyone's suprise the sword spoke, it's voice was deep with an echo to it.

"Foolish being, only my proper user can hold me. No other can do this, not even you Princess Celestia, for I the Blade of Black Thunder, Axiom can only be used by the God of War, the one you call human, the fearlessly awesome Archaeus."

"Call yourself what you might but nopony calls me foolish." she boomed at the sword. Before you could interject the sword flew into your hand but this time something was different you felt stronger. Your eyes began to glow the same color as the sword's light and you felt a burning sensation around your neck then it turned into pure hell as you fell to your knees screaming and clawing at it.

"GRAAAAAAAAAAAH! AAAAAAAAH! HAHAHAHAHAHA!" Your screaming soon turned into wicked laughter, the pain in your neck had lifted leaving an amulet like Celestia's but it looked very different from her's. You then felt a smile form upon your face. You spoke, but your voice was way deeper than usual and the amulet around your neck began to expand around your face and body, turning into armor.

"Yes, there's my armor."

"What is the meaning of this?!" Celestia yelled at you with her royal Canterlot voice.

"You don't have to yell!" You bellow making Celestia's royal Canterlot voice seem like a whisper.
"Now that I have your attention, you do not need to portray me as a threat, I do not kill the innocent but only the evil and frankly, I do not like to be yelled at." Celestia seeing that you meant no harm straightened her posture and recomposed herself.

"Right, I apologize in advance for acting that way towards you, but you must understand that Equestria is in danger of being invaded by Chrysalis and her changelings."

"Yes, I understand but you must keep a calm and collected head, even in the face of war, for that is the only way to truly finish evil. So, are we done here?"

"Yes and one more thing, I want you to be the leader of my army."

"I accept Celestia."

"Very well." She says bowing.

"Do not bow, bowing is what evil rulers force their servants to do, give a sharp nod."

"I will take that into consideration, Archaeus."

"Very wise of you Celestia. I shall revert back to normal until I am needed." Once you say this you transform back into your normal clothes. But you still kept the amulet while also remaining strong, wise and powerful.

"So Archaeus, when shall I expect you to return." You thought it over and made a response, this time sounding like your usual self.

"In 3 weeks."

"Wonderful." You turned to your friends.

"Shall we leave?" All they could say to you was a,

"Woah." You then decided to take the train back to Ponyville. On the way back Pinkie and Rainbow Dash were assualting you with questions while the others were talking amongst themselves. Once you made it back to Ponyville you walked home with Twilight.

"How'd you do all that?" You just shrugged. "Well I thought you and Celestia were going to throwdown for a minute there."

"I know but I don't think she wanted to."

"Why is that?"

"Because she needs me." You were getting tired of holding the sword so instinctively, you slung it over your back and it stayed there. "Today has been chock-full of suprises." You thought.
