Each type of magic is explained, casting is better described, and I think I explained what magic actually IS a lot better. It's a very complex article (and a whopping 2,321 words, making it the longest!), but I did my best to make it simple to understand. I might add a few images in later, but I didn't have a lot on-hand that I thought fit the article.
Some of the ideas about chemistry presented in it are truthful, but there definitely is some snubbing and erasing of how chemistry works in order to get across what I wanted. I'm no chemist, so don't take anything written here as scientific fact!
I also deleted the 'Dream magic' page as it was reworked into 'pure magic' and combined with the new page. Any links that led to the Arcane/Black magic or Dream magic pages should redirect to the new magic page, so don't worry about that.
Next I want to work on probably weather control and/or something about earth ponies' ability to control plant growth. I'm unsure, though! We'll see.
Wow! This post is almost as long as the article itself. Thank you for reading Numbers, and please let me know what you think of the revamp!
