Epic.
Listening to this has put me in a different world. When I close my eyes I see myself in that world. A world engulfed in flames. I'm seeing an entire army of beasts and demons marching. You sir, have succeeded in setting that atmosphere.
There's something I notice while they are marching. Those chants are a nice touch. Certainly add to the evil atmosphere.

This is where I see the hero entering the scene. This hero is descending, almost as if an angel, with weapon in hand. He sees what lies ahead of him. He knows what he must do and what the stakes are.

Insert epic battle here.
This is truly a masterpiece. I can tell a lot of hard work went into this. You have earned a 10 from me.
