Forbidden Knowledge.
Knowledge that, for one reason or another, should not be known to humanity.
I don't know what that knowledge is, but the Measurement of Truth has the power to uncover said knowledge, and due to the natural morbid curiosity of mankind, that was what occurred.
However, a price was to be paid for such Forbidden Knowledge.
That price, according to Professor Marcus Lynton, was the death of everyone present except me and himself.
"I won't tell you what question we asked, but I'm sure you'll be able to figure it out without much trouble eventually."
He asked me a question, so I used the Measurement of Truth to find the answer and gave said answer. This straightforward sequence of events led to slaughter.
The Professor said that multiple people discussing it is not good for anyone.
He and I were the only survivors that were present during the time of the incident.
