Just in the first 30 minutes of the first awakening the face of planet Earth changed significantly.
Many major cities were looking at thousands of their skyscrapers destroyed as violent earthquakes and natural disasters left their mark on the man-made concrete jungles.
Nearly 9 billion humans could not survive the dirty mana that had flooded in during the initial few minutes of the first awakening, losing their lives as a result whereas a billion more died due to the said natural disasters claiming their lives.
The overall population went from over 16 billion to just over 6 billion, 60% wiped out just like Gaia had already predicted.
It was a dark day for humanity, however an even darker one for the other life forms on earth, as while 6 billion humans had somehow survived the first awakening, plants and animals were not so lucky.
