--An) As promised, here you go!--
"The blue ball is mana. It is the simplest form of power that allows one to achieve a long, long life through evolution. But the process is long, and even if you are able to live thousands of years, you will eventually grow old and die. While it can be powerful, it is only a little powerful. Only when you reach a stage to break through to the Mana Plane will you be able to even be considered a baby here in the Astral Domain. While after many, many evolutions you can eventually reach the point that you can fight on par with someone from the astral domain, the length of time it will take to reach that point, you might just end up being an old man unless you are some kind of freak of nature.
