The great void engulfed all of reality. It was an entity that was more of a hindrance to all ascended living matter rather than anything beneficial at all. The void was littered with many vexing phenomena that even Deities steered clear from. It was Void's body, after all, one to vast for her to control perfectly. It had its own imperfections.
When creating a world, Deities had to push against the sturdy foundation of darkness that was the great void to create their own spaces. But that didn't mean the great void was then detached from said spaces and worlds.
Unfortunately not.
Everything in reality was connected to the great void in some form. However, while Void herself could not impose her darkness on these worlds – lest she broke several 'rules' she had to abide by, like her sisters – her bearers could do so wantonly, provided they were skilled enough.
