Animated music video for the Warhammer 40,000 universe during the Horus Heresy wars. The plot of the clip tells about the confrontation of the former brothers of the Space Marines inside the Iron Warrior Legion during the Civil War. Many Iron Warriors followed their primarch Perturabo and went over to the side of the warrior Horus, but some old legionaries refused to submit to their primarch and remained faithful to the Emperor to the end. This is the story of one such legionnaire, the last guard of one of the countless garrisons scattered throughout Iperium, who, even when left completely alone, did not give up and did not betray the Emperor.
