Princess's most faithful student.

* after events of Canterlot wedding and banishing Chrysalis and changelings *

So many years. I was under the command of princess Celestia. Ever since she recognized my talent in dealing with corruption and disharmony the hard way. Well, it's not talent like other ponies discover. That talent was gained through deep dive into the corruption. I reached many triumphs, but sadly, I'm not as powerful as i thought. That day was my lesson about powers, which were beyond my own.

I was sent to Everfree forest to investigate some sort of disharmony. Princess Celestia was worried about me. She said that I'm taking more than I can chew. She was damn right. But before that lesson, I was sure about my success. Or at least about that, I can escape without harm. Maybe over self-confidence blinded me. I was so sure and all wrong. At least I listened to Princess, when she told me about contacting her Ponyville student, if something will go wrong. If I haven't been listening to her, I would have been surely dead by now.

It was a dark night. Perfect for my work. I'm working under straight command of my Princess as a secret agent. No one knows about me. Even princess Luna has no idea, why I'm sometimes with Celestia locked inside her quarters in Canterlot. Sometimes I feel bad about this, but at least I live. Without my strong will, I would be imprisoned as stone statue like Discord. Also I didn't want someone to know about my special gift in the past. I have two cutie marks. One is my own. As most of unicorns, my own special talent is connected with magic. My cutie mark is flame. It means my special talent is fire itself and fire spells. Second cutie mark is from Shadow of another pony, who was consumed by disharmony and attacked me, when I was a bit younger. This cutie mark is far from harmony and friendship. It allows me to conjure and control a grim-looking sword. Also it gives me some sort of talent in fighting with it.

I was so proud, when I tamed that Shadow, which wanted to control me. When I realized that I was unable to completely drive him from inside of me. I offered him something, what he doesn't know. I offered him to be his friend. After some time, he was talking to me and after few days, he told me everything he remembered about himself. To be honest, that Shadow was a mare. But not only a mare, she was student of the famous Star Swirl the Bearded. She offered to share her powers with me, if I will never abandon her. After a few days, princess Celestia appeared before me. I have never seen such beauty. After few moments of investigation she aquire the knowledge about me and she was about to strike me with power of the Elements. I was so full of fear, that I started to run with wild use of magic used instinctively. After a few minutes, she determined, that I was right. She have taken me to Canterlot and observed me for a few days. She gained some sort of trust in me and started to teach me. She taught me about harmony and friendship. Not only me, but also my inner demon. After a few years, I changed my inner demon into powerful and understanding ally. She changed mostly in understanding of life. Someone could say, that she is white Shadow now.

But that day in Everfree forest, it was very hard. I was slashing through some timber wolves, when I felt it. Source of that corruption. I headed that way as fast as I could. It was far more stronger than it looked at first. Even when I was so far, I felt it strongly. When I could see it, disharmony was so strong, that even Everfree forest has been changed by it. I have never seen such an abomination in my life. It looked like normal Shadow of somepony, but it was devouring another Shadow and somehow it was gaining strength through this process. Few moments later, it noticed my presence. Even though my sword was primary for fighting with these things, I cannot hold it long under such powerful bucks and attacks from that Shadow. After a few moments, I was unable to hold my sword summoned. My sword burned out as always, when I unsummon it, but this time it was from lack of power. I was looking at that little show, which always amaze me. Long, black sword with brightly glowing red runes burning like a paper. Shape of sword have been always that strange. One third was hilt, which is wrapped in leather ended with black, simple head in shape of ring. On the other side, blade as long as pony. Blade without tip look like it was cut in half, but I know it's because this sword is for slashing but no for stabing. Blade is sharp only on one side.

It looked like that Shadow drained nearly all my power. Few minutes of fighting and i had felt like i had been fighting for hours. Without sword, I was nearly deffenseless and surprised by sudden disapperance of my sword. Shadow bucked me to head. I flew like bale of hay. That buck was as strong as being hit by a train. After I crashed in the tree, I was barely alive. With remaining power I had, I tried to cast escape spell with only one thought. Ponyville. Last thing I saw was a Ponyville library.

„Whoo“

„What's happening, Owloysius?“

„Whoo“

„Ok, I'm following you.“

Very quiet sound of wings and legs clopping could be heard from inside of library then the sound of opening of the doors.

„What in Equestria...!“
