"We are the sons of Perturabo, and our legacy is not forged in glory, but in endurance. While others chased honour in open war, we learned the strength of silence, the art of stone, the truth of steel. They mocked our siegecraft, called us bitter—until their bastions fell beneath our guns. We do not ask for remembrance. Let statues fall. Let songs fade. All that matters is that the walls we build do not crack, the empires we crush do not rise again. Iron does not weep. Iron does not forgive. It only endures — and when all is ash, it is iron that remains."
