Small fuzzy cheerful little creatures that spread and consume like locusts, leaving only destruction and tears in their wake.
As Mankind is still the dominant species on Earth, the Darwinian Demons are mostly contained. Usually they will be kept in boxes with various warnings written on them, which in ancient temples whose language no one speaks doesn't really help. Not inherently aggressive, if ignored, they will multiply very quickly and become a subplot in and of itself.
