[@Bright_Ops] Ahhh, the Hektor Heresy. I remember writing in that shitshow. It was all well and good until Lumey fucked it to pieces. As Golgothos said when he left "That guy is too useful to get rid of, but FAR too much of an insufferable prick to put up with."

Also, that is a fair form of thinking, which The Emperor also subscribed to. He didn't mind leaving aliens alive, so long as they accept Humanity as the dominant species of the universe and agree to exist under the rule of the Imperium. Hence why many alien species like the Jeokero and Felinids were allowed.
