The fourth wave of calamity separated the world. Originally the world was about the same size as earth; but after the ground cracked open, and lava flooded out aided by Mana which allowed it to cool extremely fast the planet grew. Once it had stopped growing the planet was now at least a million times larger than before, and because of the primitive technology of the people many were separated from each other never to see each other again. This lead to large scale grief as the world mourned believing each independent group to be dead.
