Closing my eyes and listening to this song... I keep getting this vision of Celestial and Infernal gods and goddesses, gathering together between worlds to behold the most powerful angel alive ascend through a portal from beyond the universe in a spectacular display of Light and energy, free from an ancient prison to aid his brothers and sisters in the Heavens and Hells against an even greater threat than they've ever posed to each other.
This angel returns to Heaven, its powerful and charismatic presence inspiring loyalty and worship, and almost everyone comes to believe it is there to save them, to lead their armies against the most powerful of primordial foes. Even Michael is convinced and potentially blinded by optimism, of once again feeling united with his brother.
Yet they all know what could happen. Never before has any one being been able to inspire such loyalty from both Hell and Heaven. This being may very well defeat this apocalyptic primordial threat... but the thought of what could happen to them, and the Heavens and Hells, and the entire cosmos, if this being continues to grow in power...
