I wouldn't kneel to a man who used me, tossed my empire in the trash, and manipulated all of my actions for his benefit. I can't and refuse to kneel. I usually admire the villains because of their plots but Valkorion basically laughed, spit on the empire, and now is trying to throw us away for his eternal empire. I can't kneel to him. I refuse to. The only characters who would kneel to him would be my smuggler/operative just because how they work in the shadows and directly opposing somebody is a big no no.
My assassin main would rather die than kneel to an emperor who treated us like garbage.
