what Thordan said and how we appeared to him momentarily in that scene, Thordan's 'death' scene at the Singularity Reactor was just him being unable to reconcile his defeat - he had become a Primal himself after all and
killed for good an Ascian, a 'servant of the darkness' after all! Defeating a 'servant of the light' should have also been cake! And yet he folded faster than Superman on laundry day, and just could not accept how this mere mortal could bring him down.
So he envisioned us as some kind of monster, some unknown entity that he could not understand or accept, regarding us a blank featureless entity. It was a
visual metaphor for Thordan's bewilderment in his final moments, nothing more.
