Hi
So I gave my thoughts about how to represent the abhumans of an old WD article in Only War in a thread where someone had done just that. Soon after I got to thinking, why just sit there and say how you would do it when you actually can do it.
So here they are;

I plan on adding more abhumans in the future but this is a good start.
And Sorry if I stole an idea from that thread, there is room for both interpretations.
