I would like to suggest a role.
The Corrupted.
These past users are dead

No matter what..
They all are different.
They can look like zombies which grayish skin or pale, or can be black..dont be racist. They travel in packs, ganging on survivors of past battles..
They would not be a serious gang unless further approved.
You can decide what to do
I just thought this so hard, and I just like the title.
