The Doomsday Countdown. A countdown that nobody ever expected to happen. A siren sounds underground with such power, people everywhere hear it. A siren attached into the core of Earth. It was built thousands of years ago, where technology fell and later rebuilt. It was built to sound every 3,521 years, 3 months, 1 and a half weeks, fifteen minutes, and forty-nine seconds. The sound of doomsday is heard with great attention. Everyone panics.
The Countdown has begun...
