Dustin however woke up unharmed, and learned that the world was about to go into ruins basically, and that some humans would be taken away in a few days as 'earth's warriors'.

As it would turn out, on the D-day, Dustin is one of those that were taken. But, this might turn out to be an opportunity rather than a curse, as some night before this day, something interesting happened.
