Ahriman's POV

I walked towards the ruins of the old Castle of Friendship in the Ponyville Wasteland. Midnight had sensed an influx of Warp Magic, and I had decided to investigate it personally. Behind me were two Terminators, clad in the black armor of my honor guard. I stared up at the mostly destroyed castle, crystal walls blackened from battle and the corruption of Chaos. I opened the door, which then fell to the floor with a bang.

“So much for subtlety.” I muttered, before pressing forward. I walked through the destroyed walls, examining every detail.

“You know, this would make a perfect Temple to the Chaos Gods.” I muttered absent mindedly. The Terminators said nothing. I opened the door to the throne room to see a pinkish unicorn with a purple mane, that included green highlights. She sat on one of the six crumbled thrones, an evil grin etched in her face.

“You must be the Warmaster Ahriman.” She purred, sitting up from the throne. “It's an honor to meet you, after all I had heard about your little war.” a scroll floated up.

“Indeed I am. Who are you?” I asked, narrowing my eyes and reading the scroll with my enhanced vision.

“I am Starlight Glimmer.” She answered, the table in the middle of the thrones glowing, before energy rose out of it. The Terminators opened fire with their bolters, the bolts bouncing off the energy rings like they hit an invisible wall. Starlight crumpled the scroll before tossing it at us. A half sphere appeared in the air, and Starlight flew into it, before it closed entirely. Whatever powers were at work vanished immediately, and the crumbling room returned to normal. I picked up the scroll, examining it. The weird portal opened up again, dragging me into it.

The other side of the portal led me to an area that was quite familiar, but shouldn't have been possible. The main hall of the New Lunar Republic, where Luna had first become Nightmare Moon. I was in the backstage, with my past self talking to the whole of the Lunar Guard, and Luna by my side.

“Time Magic...interesting..” I muttered to myself. “Let's see where this ‘Starlight’ is going with this….” I snuck to the side, and invisibility spell enveloping me in shadows. As Thestrals, or batponies, as they were during this era, filed out, my past self turned to Luna, beginning a conversation. After five minutes, he reached out, beginning the spell to transform her. However, a beam of magic struck out of nowhere, striking my past self and cutting out his focus. Luna fell to the ground, crying out, and I followed the trail of magic to see Starlight grinning madly.

“You...traitor!” Luna roared, standing up and staring my past self down. “Guards!” A large amount of Lunar Guards burst into the room, spears at attention. “Ahriman, you are charged with attempted assault of me, and shall be executed!” She roared, before charging her horn. I took action, teleporting in front of her, firing a beam of Warp Magic as she fired her own beam. The two beams met, exploding at contact.

“Who are you?” My past self asked, pulling out his staff. I activated a spell, a shield forming around us.

“Not important. Right now, you need to get out of here.” I told him. He nodded, before teleporting away. The Time Portal opened up again, dragging me back in.

When I fell out of it again, I was back in the Castle of Friendship, or whatever it was called. However, it looked more...pristine. No signs of decay could be seen. I landed on my feet, looking up. Six ponies stared back, eyes wide in surprise. Three of them were familiar. Twilight, Rainbow, and Applejack, along with a white coated unicorn with a purple mane, a yellow pegasus with a pink mane, and a pink Earth Pony with a pink mane all sat on thrones, gazing at me with fear. I immediately teleported to Canterlot, landing in the gardens. Confused, I looked up.

A stone Khârn and Zhufor greeted me. I stood there, shocked.

“That Starlight...she did this!” I roared, bashing my maul into the ground. The ground parted beneath it, creating a large crater. I grabbed my anger before it got out of control, and calmed myself.

“Let's see...she used that scroll, which I now possess, to go back in time and change the past. In order to return things to how they were, I will need to return to that moment and keep her from doing this. Let's see...how to go about this…” I muttered to myself, only to have my train of thought broken by a spear that broke against my armor. I glanced to its origin to see a large group of guards, spears held high.

“Halt, creature!” They yelled. I lunged forward, my power claw removing the leader's head from his shoulders. My maul flew out, crushing the rest under it’s might. I teleported back to the castle, holding the scroll out and activating the spell, before flying into the portal.

××××××××××××

Once again, I was at that period of time. A beam of energy flew at me, hitting my armor and freezing me in purple crystal. Starlight walked forward, grinning.

“Sorry, Ahriman, but you won't be stopping this.” She cooed, patting the Crystal prison. I growled, Warp Magic destroying the crystal. My hand flew out, the power claw gripping Starlight in a deadly grip. I pulled out the scroll again, before pulling us back into the present.

×××××××××

We reappeared in the ruined castle, as it was supposed to be.

“You hold no power over me, vermin. What you did was commendable, and you are the first I've known to try to change what I created. However.” I gripped her horn in my other hand, breaking it off. She cried out in agony, unable to move in the grip I had her in. I brought her up to my face, growling. “Even if I had a use for you, I can't take the chance. But… I am a merciful warrior.” I opened a portal to the Warp. “I'll let you live. In the Warp.” I tossed her in, her screams muffled by the chaotic beauty of the Warp’s song.

“When you see Tzeentch, tell him Ahriman sent you. Then apologize on my behalf for the inconvenience.” I growled, before closing the portal, cutting off her screams. The two Terminators stared at me.

“Tell Midnight that the anomaly has been dealt with, and that we are returning to the base.” I ordered, before realizing that they didn't know how to use the Warp. “Never mind, I'll send the message myself. Let's go.” I sighed, before walking out the door.
