Just a little thing I did to highlight the Auraras' powers. They can manipulate their aura, and depending on their emotions, it changes their abilities. I used Quarius as the guinea pig, but all of them have the same emotion base. Here's a brief explanation.
Green (Calm/Neutral): The standard aura. The Auraras try and keep a serene outlook to life, so this is the aura color that shines the most. Does standard damage.
Yellow (Happy): Caused by positive emotions. Has the bonus effect of being much brighter than other aura colors and can be used to light up darkened areas.
Blue (Sad): Caused by negative emotions. Hard to control, but has the added effect of having a cold touch.
Red (Anger): Caused by rage (Or...by Zorch. Because he has a tendency to cause it.) Hard to control, but with the added effect of having a burning touch.
Grey (Ill): Caused by illness, regardless of emotions connected with it. Extremely weak.
Pink (Love/Bliss): Caused by lovestruck or extremely positive emotions. Has a dizzying effect to it.
White (Fear): Caused by feelings of extreme terror. Extremely powerful, but extremely difficult to use.
Orange (Confusion): Caused by feelings of indecisiveness. Has an immobilizing effect, but also hard to direct.
