Because of the Fall, the most affected regions on Earth is Australia, China, and India.
China population which reaches nearly one billion is the past is now only around a handful of million people scattered all over the world
India is the same.
Their population was rising before the Fall but the Fall put a full stop to that reducing India population to only around two million people.
The more populated a place is before the Fall, the stronger the monster that was there. Japan was an exception
India look a lot of time to recuperate and their warlords that rise during those unstable years of the Early Fall did not help
India now have a problem that they never had before.
They have too much land and resources but not enough people to live in it.
Because of that Indian warlord lack people.
