Greetings Mortals, I am but another energy which will manifest to join this bloody and glorious war. May you be foe or ally, it'll be a pleasure to make your acquaintance. Remember. Ulthwé is watching you.
Much can be learned from these creatures. Unlocking their minds with potent psychic assaults shall be wondrous!
The part you will have is laying siege to his craftworld when I pry the location from his twisted dead mind.
Since when do you have authority over me? Why would I attack a craftworld when there are much higher priority targets?
