Dark Matter Fifis are a race of fifis classified under evil. They are located on Zmenia in the ruins of a once profitable city that got destroyed by a chaos bomb.
Dark Matter Fifis are extremely dangerous and you should not go near them as we are not sure if they are contagious or not. Either way, they should not be brought into cities as the result could be devastating to the city and its inhabitants.
After being studied by excalishman, it turns out these fifis release a small chemical into the air that withers plants around it.
