Who are these people? And what is this ritual?

Have I really have been away for so long?

They've turned their backs on, once loved icons...

... but the god you left is now back

Behold! - it's the god who fell from earth

Enter now this world

Retake what is yours, and seize the golden throne

Greet the god who fell from earth!

Men are fleeting, for their sons and daughters are bleeding...

One should never forget the gods... sound out my triumphant return

Behold! - it's the god who fell from earth

Enter now this world

Retake what is yours, and seize the golden throne

Greet the god who fell from earth!

Behold! - it's the god who fell from earth

Enter now this world

Retake what is yours, and seize the golden throne

Greet the god who fell from earth!

The god who fell from earth could be you...
