Explanation:

Adam and Bridget were walking home one night from a Free the Real NYC meeting. They were walking in the shadows to avoid being caught by the curfew police when they tripped over a huge titanium cylinder. There were three words etched on it that they could read. "He will prevail?", Bridget asked quizzed, "What's that supposed to mean?" Out of curiosity, Adam opened the container. They shone their flashlights at the titanium cylinder as they gasped in awe and relief. It was a news article from December 13, 2505! It was written about how the leader of the formerly NYC was planning to build a machine that could wipe out the entire city! They rushed back to the secret base of the Free the Real NYC resistance. They put the container on the table. Now that it was in better lighting, they could read the rest of the etchings. They read ψοφώ, Greek for "I'm dying." They learn that the etching was written by the founder of the resistance, Henry Gihigal. He wrote it when the leader of the Cultists, Tabea Thomas, was torturing him with methods unheard of. He wrote the "He will prevail" section speaking of the resistance. The "ψοφώ" was to tell the resistance to choose a new leader. They started planning their attack to make sure that the machine was destroyed.
