They're small. They're unpleasant. They're the Grubbers, feared and despised by all other peoples of Desolation Earth.

Why? Because they steal everything they can get their knobby little fingers on. They're hairless and have rough, almost scaly skin, and are prone to diseases such as Eye-Rot and Skin-Rot, as well as conditions such as Proteus syndrome, withered limbs, and stumpfoot (see Popups 1 and 2). Even when not armed, they're extremely dangerous-- they're very strong for their size, they have claws, and they fight viciously. Also, they like to bite-- and a bite from one can be fatal because of the virulent bacteria in their saliva. Altogether, they're a thoroughly nasty race-- so much so that parents of other races frighten their children into obedience with the threat:

'You'd better be good, or the Grubbers will get you!'
