The Break the World event will determine whether literally everything was fake and all the important character should commit die, or whether we're all going to die at the hands of gigantic corporations who want to have 8-21B for their own evil purposes. The Break the World Event was initiated when Hat Kid walked out dramatically and revealed that everything was a lie and most people were fakes created by the computer. How this is possible is unknown. The fighting for the sides don't take place in the roleplay, but rather in how the various DMs lead the story.
The Break the World event with Thomas being handed keys to the world with instructions to destroy it. And so the world crumbled. Everything seemed lost.
But out of the love for those who were lost, when the world was on the brink of destruction, it was reborn. And thus 8-21B Neon was born.
