Ages ago, there was an apocalypse caused by one ever-so-sensitive catalyst.

"The events that followed that moment are spoken of sparsely in local mythology, as those who know of that tragic day tread carefully around the topic in fear of recreating the catastrophe that devastated the lives of so many innocents. Those who survived to this present day are known as sages, for their wisdom and willpower have kept the rest of us safe simply by sealing their lips."

"Sealing their lips? About what exactly...?"

"Pizza toppings."
