The lost blades of Equestria

When we reached the safety of the trees, we looked at what we managed to grab. A lighter, a bottle of some alcoholic beverage, and a white cloak made for ponies. I used my hidden blade to cut a strip of cloth off the cloak and made a molotov cocktail. My friends were surprised I knew how to do it but I just said to them:

"When you live in the house of an end-of-the-world prepper and a neat freak, you pick up a thing or two." We continued to travel northward until we decided to rest by a creek. "Does the name 'twilight sparkle' mean anything to you?" I asked out of the blue.

"No, why do you ask?" Said Andrew.

"I heard the hybrid say that name to the purple unicorn that protected us. I thought it might give us a clue to where we are." I said before Charm snapped her fingers and said:

"We're in equestria! Why didn't I see it sooner?" Me and Andrew were confused. "Don't you see? Mythical creatures, Civilized talking ponies, Twilight Sparkle. We're in the My little pony universe!"

"So what your saying is, we are in a TV show..." Said Andrew. I laughed at what he said until I saw that both he and Charm were serious.

"Your serious?! We're in a TV show?!" I knew we were far from home, but not in another reality!

"Look, we should not focus on that. We should focus on finding a way home." Said Andrew. We then decided to travel northward until we find another settlement that is hopefully friendly or at least neutral to us.

Meanwhile, in the canterlot dungeons...
Twilight was in a dilemma, on one hoof was helping princess Celestia capture the humans and getting set free, but on the other hoof was helping the humans return to their world and possibly getting executed. Of course she wants to live but she also wants to do what's right. She was pondering over which to choose when she heard commotion outside her cell. Apparently, the humans she protected are heading straight to canterlot!

We were heading northward when we saw a city built on the side of a mountain. We used stealth to enter and look around for anything useful. We found a few armaments in an unguarded armory which included, but not limited to: Two shortswords, three spears, and six daggers. We snuck into what appeared to be a castle and were looking around when a guard spotted us.

"Raise the alarm! We have intruders!" She said. I ran up to her and stabbed her with my hidden blade, killing her, before we ran down a set of stairs to our right. We ended up in what appeared to be the dungeon and we were about to go back up the stairs when I saw the unicorn from before.

"Help me, please..." it said with puppy dog eyes.

"Are you twilight sparkle?" I asked, the unicorn nodded and I broke the lock of its cell saying: "Come with me if you want to live." Andrew just looked at me and asked:

"You always wanted to say that, didn't you?" Before we ran back up the stairs.

"Yeah, it made me feel like a hero." I replied. With twilight sparkle right behind us, we ran from the castle and escaped into the sunset.

At the same time...
Princess Celestia was livid because not only did the guards fail to catch the humans but they let twilight sparkle escape as well. She used her magic to toss a table out the window then screamed out of said window. When she calmed down, she ordered a kingdom wide pony-hunt for twilight sparkle and her human companions.

We camped out in a forest west from the city, hiding from the ponies searching for us. Twilight shared stories from her world and we shared stories from ours. She was shocked when we told her about the two world wars, the atomic bomb, and the war between the assassins and the templars. When she told us the hybrid, named princess celestia, controlled the sun and the moon, we were shocked that we battled her and lived to tell the tale.

"What is the assassin's creed?" Asked twilight. Me, Andrew, and Charm huddled together and discussed over it.

"Should we tell her?" I asked "she is not an assassin."

"But I'm a templar and I know the creed." Replied Andrew.

"Because you are a former assassin, not a pure templar." Said Charm.

"Okay, I have an idea..." I said before whispering my idea to them.

"I agree to this." Said Andrew after I told him my idea.

"I am worried it might backfire on us, but I agree." Said Charm, obviously concerned. We all broke the huddle and I answered twilight:

"If you want to know the creed, you must join the brotherhood..."

Twilight was shocked. To become an assassin is treason, punishable by death! But, she is already an outcast from equestria and she already is a hunted pony "If that be the case, teach me the way of the assassin..." she said after some thought

After I crafted twilight a set of hidden blades out of the daggers we stole from the armory, I told her the assassin's creed and she vowed to uphold the three tenets of the creed. The tenets being:
1. Stay your blade from the flesh of an innocent
2. Hide in plain sight
3. Never compromise the brotherhood

"Now, apprentice Twilight, I welcome you to the brotherhood of the assassins." I said as I gave her the cloak we grabbed from ponyville and the pair of hidden blades (which I modified to allow her to use them).

"I just realized, We never told you our full names." Said Andrew "my name is Andrew L. Wellington."

"My name is Charm A. Valery" said charm

"My name is Shadow S. Limgenco" I said " And before you ask its pronounced Lim-heng-co"

We continued to chat Twilight, Charm, and Andrew called it a night, I stayed awake to keep watch for anything or anyone that might be a threat to us.
