You

"Everyone has an Angel. A Guardian who watches over us. We can't know what form they'll take. One day, old man. Next day, little girl. But don't let appearances fool you, they can be as fierce as any dragon. Yet they're not here to fight our battles, but to whisper from our heart. Reminding that it's us. Its everyone of us who holds power over the world we create. 
You can deny angels exist, Convince ourselves they can't be real. But they show up anyway, at strange places and at strange times. They can speak through any character we can imagine. They'll shout through demons if they have to. Daring us, challenging us to fight. 
And finally this question, the mystery of who's story it will be. Of who draws the curtain. Who is it that chooses our steps in the dance? Who drives us mad? Lashes us with whips and crowns us with victory when we survive the impossible? Who is it, that does all of these things? Who honors those we love for the very life we live? Who sends monsters to kill us, and at the same time sings that we will never die? Who teaches us what's real and how to laugh at lies? Who decides why we live and what we'll die to defend? Who chains us? And Who holds the key that can set us free...
It's You. You have all the weapons you need."
