A race of creatures made out of darkness. Blues are composed of flesh made of healing goop, which can be torn off and applied to fellow aliens or bathed in to feel your mental stress go away. Blues are the most emotional aliens of Yang, often overprotective and highly supportive. They lack in combat experience and need a leader to thrive, though. Blue aliens can absorb the effects of other aliens to gain additional power as well, in addition to that, they can also change the concentration of light on the battlefield. 

(Yes you can make a Blue if you'd like)
