So, I didn't really like what happened with the first Yume drawing, so I decided to reattempt it.

I used four layers on this.
WHOEVER MADE LAYERS IS A FREAKING GENIUS
Oh, and also:

CONCEPT TIME LETS GO!
Mostly this was made for.... an abandoned roleplay... ha...

SO IN THE LOGIC OF... souls.... DIFFERENT MAGICAL CREATURES CAN OBTAIN DIFFERENT SOULS!

One of them is an Anger Drive, which are the most dangerous.

If a really powerful creature falls into despair, yet blames another person for all of it, instead of their soul morphing into a Black Orb (I shall explain when I draw one), it becomes an Anger Drive, shown above.

Why its so dangerous, you ask? It changes the way your magic power works, so it doesn't just automatically quit when you have used up a lot of it. Instead, you can keep using this magic, BUT it drives into your life force, potentially killing you.

You can also die by completing revenge (since the Anger Drive has no fuel anymore) or go into a despair in which you think your efforts are useless (which will cause it to self destruct). These are really hard to avoid because it locks all emotions except for anger away.

I don't think you guys wanted a 100 or so word explanation on a small picture. Im sorry.
