Kill the dragon
It sounds really good. It fits well with that quest you talk about, with Gods. I would certainly add some dragons.
I do not really like the intro, it doesn't match the aggressiveness/fighting feeling I've got when I listen to your song.
What you've managed to do really good is that though the song's got a fighting melody, it's still soft to the ear and it doesn't bother a loop listening, for instance in a video game.
It's maybe a bit long for the few different variations I could define. Maybe shorter (song and intro) would be better, I guess. But it's all personal.
Good job !
