The void declaration Father God made against Abyss Xyrin was actually just a precaution, because no matter what, this generation of Abyss Xyrin is saving all Order Worlds, and we have neither the stance nor the motive to declare war against her, especially since both sides are currently allied. However, Abyss Xyrin herself is an extremely dangerous entity: her mindset ensures that as long as her "Empire" conflicts with any other Order World, she will immediately transform into a disaster of the Void—just like during the initial years of Da Ye.
It's beyond good and evil, beyond factions, destroying worlds in a completely neutral and indifferent manner, which is more dangerous than any "Demon King" with evil intentions because she harbors neither malice nor goodwill, merely a disaster machine that wouldn't stop short of self-destruction.
