Imperial Fists were the Seventh Legion of the Legiones Astartes, led by the resolute and disciplined Primarch Rogal Dorn. Originating from Terra and later Inwit, their mastery lies in fortification, defense, and siege warfare.

During the Horus Heresy, they were summoned by the Emperor himself to fortify Terra and prepare the Imperial Palace for the coming siege. Dorn led his Legion as the Praetorian of Terra – the unbreakable shield against treachery. Their fierce rivalry with the Iron Warriors culminated in bloody clashes during the Siege of Terra.

Imperial Fists excel in precision firepower, endurance, and unyielding loyalty. Their elite units such as Phalanx Wardens, Templar Brethren, and Huskarl Terminators form the backbone of any defense. In the Horus Heresy system, they gain unique rules for fortified positions and enhanced defensive tactics.
