Very few know what they are, or where they come from, let alone how they came into existence in this world.
What is Dust, exactly? That is a question no one can answer at the moment, nor will we ever answer it. It constantly remains out of reach, out of sight, and out of mind.
And many other things in this world.
There is so much that remains a mystery, and so many things that remain hidden from human eyes and minds. Even with the Faunus and Mobians, there is so much we don't know about our world, or what threatens us as a whole.
We just happen to be caught in the middle.
But there are those who wish to take a stand against these threats, and they are perhaps the bravest of us all. Except for those who seek to use what they were given as a means to an end in order to serve their own selfish ambitions. I should know. I've fought numerous people like that, not counting the Grimm, or an even bigger threat to the human race as a whole.
Humans imbued with the essence of the Grimm. How do they come into existence? What role do they play in this never-ending war against the Grimm? And how do they get such essence? What does it do to them? These questions may never be answered, or they may be answered in some far future time well beyond where we are currently. The future is never set in stone. That much I know. How, do you ask? Well, that is a tale for another time.
Right now, this tale is about how I became involved in the Grimm war, and how it forever changed my life. And about how much I learned about the Grimm, and of how much really threatened our world.
My name is Joseph Matthews, and this is my story.
