Nocker

Nockers are a kith in the relatively popular "Changeling: the Dreaming" role-playing game published by white wolf game studios. Like each of the other kiths in Changeling the Nockers have two special abilities and a special flaw which serves to distinguish them from the other kiths. Nockers are able to forge chimera, that is imaginary objects which other changeling's can see and use, and they also have a close affinity with machines, and can often intimidate any machine into working correctly simply by yelling at it. Nockers also swear continuously. It is virtually impossible for them to prevent an endless stream of curses and blasphemy from issuing forth from their lips, which puts them at something of a social disadvantage. Nockers are generally short and pail, they favor complicated victorian clothing.
