Why is everyone so sure that the fallen is the hive? You do realize that the hive actually are insect like, and so that the thralls are just simply worker ants for the colony? No brain required for lifting a pole. Acolytes are actual overseers for the thralls, knights are the "titans" of the hive, wizards or commanders, most likely with an actual brain, used for coordination of hive forces. Orgers are literally tanks, looking at one chained in a video, most likely completely brainless, and need to be carefully monitored so they don't smash other hive. Great chance of a queen because of eggs found. Also, why would they want to convert other races? They despise other life, and want to eradicate it all. Their crusade of darkness? Am I the only person who watched the video for them?
