Long ago, when Princesses Celestia and Luna both ruled together, a war was fought in the shadows between Luna's Brotherhood of Assassins and Celestia's Order of the Knights Templar. Blood was spilled across Equestria until the banishment of Princess Luna, and the Brotherhood went into hiding, while Celestia and her Templars gained complete control of Equestria. The return of NightMare Moon and rebirth of Luna brought the Brotherhood out of hiding and the war between the Brotherhood and the Templars began once again. The Brotherhood's targets are all known as the "saviors" of Equestria, the bearers of the Elements of Harmony.

Spike, banished from Ponyville for a crime he never committed, turned from his friends, he walks through the Everfree, were someone he never expected sent him on a new adventure and life.

He was called Spike, but now he will be the Dragon Assassin.

Note: kinda like an assassin's creed crossover

Assassin's creed belongs to Ubisoft
Mlp belongs to Hasbro and Lauren Faust

Oh? You want to hear a story young ones? Well I may have a story for you tonight. Now this little tale of mine is about a young man who suffered an accident and must fight a secret organization to recover the shattered remains of his mind. He'll meet new friends and old, travel across the land of Equestria, and hunt down the people who think he is dead.
Now it's not my place to say whether you believe this story to be true or not, but what I can tell you is that this story is filled with action, adventure, some comedy, maybe even romance, sword fights, a little blood, and old enemies and new alike coming out of the shadows.
So what do you say kids, want to hear about the Assassins and Templars?

I read a story, Assassin Spike, (I have no idea on how to put in a link) go check that out, it's a great read. So I decided to take a crack at the Assassin's Creed crossover idea. If the author is reading this, I give you the credit for the inspiration for this story, if not for your story, I wouldn't have thought of this. I think that this story will be the one I'm hoping for though. Anthro Spike and all other characters, so if you don't like that kinda stuff just don't read. Also this story is in the future.
Live long and prosper my fellow readers
