Capítulo 166: Why is it necessary

Aether is one of the essential elements of life.

Just like how the physical body needs a mixture of various minerals to take form and grow, it also needs just the right amount of Aether, Mana, and the blessings of Life. This rule not only applies to almost every living being but also to the entirety of the world. The earth, the air, waters, stars, all and all have at least a tiny bit of Aether in them, just the right amount to make them what they are. 

So what happens when this Aether, one of the essential elements of this world, is forcefully extracted from it? What if the world is deprived of this essence?

The first affected beings would be those extremely sensitive to the changes in Aether; elementals and monsters.
