Entry Ten:
Nothing. The closest I have come to an answer is using dark magic. Which, is what I suspected in the beginning. This isn't groundbreaking. Dark magic had some pros, other than corrupting the user, it can manipulate our reality. Much like elemental magic can, but elemental magic is rare. I suspect Twilight was only able to "experiment" with it before her death was because of her connection to the tree of harmony. That tree feeds off the unbalanced nature of the Everfree Forest and the magic of Equestria itself to become as strong as it is. It turns the magic into a positive. Dark magic, as powerful as it is, is dark for a reason.
Years and years ago I burned most of the dark books available to the wider public to avoid another pony turning corrupt. Turning into another Sombra. I had to go into the Canterlot Catacombs. Built within the mountain Canterlot was built on, to get the books that survived. The ones I hid away for future use if needed.
I checked Starswirl's journal. He investigated dark magic in one of his journals. He wrote about his apprentice, Sombra, who came from the Crystal Empire. Sombra became corrupted and obsessed with power and living forever. He used magic to manipulate reality. Starswirl refused to write down what he did.
All he said was:
"Sombra interacted with the Dead. It was unnatural. It was evil. Magic is NOT supposed to be used in this way."
Sombra has not returned since Luna and I banished him. Scientists have calculated he will return soon. Within the next decade.
This brings up a whole other set of issues I don't have time to plan out how to fix right now. This is driving me mad.
I have begun talking to myself. Again. I haven't done that since my youth but now I am reduced to talking to myself to remember I am still sane. To remember my actions matters. That I do have control. That I can stop whatever Twilight is trying to accomplish.
There. There I go again. Lying to myself.
I need to face the fact that I have failed another one of my students. That she has become a monster.
A murderer.
She has not written me a letter yet. It is late. As I am lowering the sun I am dreading that there is still time for her to-
Sonic
Rainboom.
Sonic Rainboom.
A Sonic Rainboom just shook Equestria. Those colours from the sky are disappearing as I write this. I need to order the guards to Ponyville right away. Rainbow Dash is the only pony (To my knowledge) that can cause a Sonic Rainboom. It went off far too close to the ground.
The staff are marvelling at the wonder of the magic they have witnessed.
All I can see is death clouded by light.
