It is believed modern society and technology are the weaver’s gifts to humanity. As such the main agent of the weaver is society itself. The bureaucracy of government, the police and human witnesses are all major problems encountered by the Garou whenever they operate within the city. That said, most of these agents aren’t even aware of the Weaver’s existence. Thus the Weaver has no direct control over the actions of any individual person.
In the Umbra the pattern spiders are the more obvious agents of the Weaver. They appear in large numbers in the cities penumbra and can be particularly dangerous when roused in large numbers.
