Fifty years ago.
To be precise, on December 20, 3025 of the Federation, something big happened.
It was this incident that led to the establishment of Homeland Security.
That day, an explosion occurred at the Quantum Collision Experiment Center located outside the Federation's special zone.
The next day, the Federation Senate held an emergency meeting and passed the draft. Then, the next year, they passed a resolution and established Homeland Security.
Everyone thought that it was the explosion at the Quantum Collision Experiment Center that led to the appearance of Homeland Security.
However, such a statement was right and wrong!
"Do you know why the explosion at the Quantum Collision Experiment Center led to the establishment of Homeland Security?"
"I know, I know."
