Well, not only did the corpses of Tokugawa and the Fabius Family draw a pack of wolves vying for them, but the remains and rotting flesh left by the East City Society and the Shura Society also attracted a bunch of maggots.
After the local gang leaders in Night City were taken out, a whole bunch of unclaimed territories opened up in the city, with no one to collect protection fees for the business streets and nightclub clubs, giving rise to various lower-level gangs like bamboo shoots after a rain. Corporations at least maintained the facade of civilized people, engaging in corporate warfare and coaxing people to jump buildings and whatnot. The thugs were more direct, resorting to chopping people, arson, and spraying with machine guns.
There were turf wars in the streets, and a new era of warfare had commenced in the scramble for the scraps left by the corporations.
