Ahriman's POV

As I sauntered up to the stage, I knew the reaction I was going to get. It had been a month since we took Manehattan, and the Loyalist Guards had suffered dearly, both from trying to reclaim the city, or just doing nothing. Just as planned.

"Warriors of The Legion! This past month has been very rewarding! After the reinforcements arrived, as you all know, we secured the city, and beat back every attack sent by the Loyalists. Now, not only have we starved them, we have also culled their numbers! But, a recap is not what I brought you here for." I took a deep breath. "Today, we will finally march upon the Solar Empires soil, and lay seige to Celestia's castle itself!" I told them, eliciting cries of shock.

"But, Lord Ahriman! We do not have the resources available to attack the castle! We would need to recall all forces that have been raiding any extra trade routes!" A Soldier called out, to which many mumbles of agreement were heard. I raised my hands to calm them.

"I have already done this. And they have brought the Spoils of they're journey as well. We now have much food, as well as some catapults. Khârn has accepted my offer to spear point the assault, which will be led by Princess Luna herself!" I told them. Many more cries of shock were heard as Luna stepped out of the shadows in full battlegear. Most of her body was now as black as the shadows, and her eyes glowed a sickly green.

"Fear not, my Soldiers, for we can, and will, win this fight. Ahriman speaks true. Celestia's forces are weakened. Now is the time to strike!" She shouted, to which many cries of approval sang out. I smiled.

"We march today! Grab your wargear, and prepare to move out in three hours!" Luna shouted, and the crowd dispersed, leaving only me and Luna left. She looked to me.
"Ahriman, I simply must thank you for all the hard work these three years. Today, the war will be over, and Chaos will reign!" She stated, then blinked. "What? Why would I speak of something so foul as if to were a good thing?" She muttered, before I took action.

"Sorry, your majesty, but Tzeentch needs you now." With that, I forced my powers upon her, warping her very mind itself. All of her mental wards broke, and she screamed, a scream so loud and horrible, it couldn't be heard by the likes of the batponies, who subconsciously shut it out, leaving only a minor headache. After about ten minutes, the screaming stopped. Luna looked up at me with a very calm stare, devoid of any emotion. I smiled.

"So, your majesty, shall we prepare for the coming battle?" I asked. She smiled.

"Yes, of course, Lord Ahriman. Together we shall crush my horrid sister and her precious light. And then, the night shall last, FOREVER!" She cackled, her eyes slightly misty. I merely smiled again. All those years of silently sending my thoughts into her mind had paid off, as I doubt I could have defeated her mind at full strength. I walked off to prepare the final part of the plan, watching as a New Moon rose high in the sky.

Author's Notes:

Sorry for small chapter. I just felt like putting a quick Cliffhanger for the final parts of the war. Any constructive criticism is welcome, and point out any spelling errors I made!

Also, as a note to what just happened, Ahriman made the Nightmare Moon process speed up a little bit more than the original canon version.
