Whether it's humans or deities, including the world itself, when reaching a dead end, it's definitely not the help offered by others.

Although they are an absolute race that will not perish with the destruction of the world... the Goddess of the Earth's World Tree clearly placed its last bit of power in that ancestral valley, ready to pack those bears inside and take them away.
But it also proves that, when forced into slumber, the Goddess of the Earth has also prepared for the worst.
