"I am what remains of the Song of Salvation. I am His will rendered in silent light, sent forth to guide a
billion vessels home. I am what remains of the Emperor now that His body is dead and His mind is
dying. It is a death that may take an eternity, but it will come. And then I will fall silent with His final
thought. [...] I stare into eternity and witness the dance of daemons. I sing forever into the endless
night, adding my melody to the Great Game. I am Imperious, the Avatar of the Astronomican."
