I know why now. anger feels.....fantastic letting out all your frustration was so liberation that I couldn't stop. It started with a taste when I got angry at pinkie, but then they became more and more frequent, and the explosions only grew more powerful once I ascended, I thought I had it under control.

That is Until I ruined the canterlot library. Its not my fault! I had been waiting for that book for years and they give it away before I arrive. After my rage took hold I had leveled a good section of canterlot....and the fires didn't go back. my main stayed on fire, scorching anything that got too close. My purple coat is now white from the heat. And the only thing I seem able to control are my wings, they feel the same but made of fire, and dissappear when I don't pay attention to them. And It seems my magic is burning at a constant rate...fueling the fire. however instead of weaker, I feel stronger than I have ever been. I must investigate this phenomenon. And test its limits, and to do that I need test subjects. and lots of them.

Discoveries

1. It appears that my anger is a lot harder to control now than ever before. even slight irritation is enough to scorch anyone around me.

2. I have noticed whenever I...explode the beings that are not targets of my anger suffer no damage from the heat and fire.

3. I have found that a simple heat shield spell prevents people from...dying when they get close enough to touch me. I have decided that I shall not cast this spell every morning as was originally planned, as most things who try to touch me without asking first usually want something else.

4. The air feels cold to me, and water is so frigid I think I might freeze solid, but the shield spell seems to work both ways, preventing me from being uncomfortable in 'average' temperatures.

I shall add more discoveries as I uncover them. I need to do more research.
