"So, simply put, the damage in the Universe's Foundation was a foreseen outcome. It was the result of the destruction of the Extinction Sphere," Gem concluded the answer to the first question.
"Now, your second question. Why did the Universe get split in half as a result?" Gem thought about the past as he recounted the events. "Because I was forced to initiate the Severing Formations Array ahead of time, I wasn't able to control its power as well as I intended. As you know, the formation was going to split the Yin and yang energies inside the Extinction Sphere. With that, they wouldn't be able to complement each other anymore."
