Summary of History (Horus Heresy – 005–014.M31)
The VII Legion was one of the original Legions created on Terra. Known for their stoic nature and exceptional skill at fortification and siege warfare, they earned a reputation as the Emperor’s most reliable defenders. Upon reuniting with their Primarch Rogal Dorn on Inwit, the Legion fully embraced their role as the Imperium’s shield.
During the Great Crusade they were frequently assigned the hardest compliance actions, building mighty fortresses across conquered worlds. They became the Emperor’s personal honour guard and were entrusted with the defence of the Imperial Palace on Terra.
Key events during the Horus Heresy (005–014.M31):
Rogal Dorn was named Praetorian of Terra and given overall command of the Imperium’s defences.
The Imperial Fists were responsible for fortifying the Imperial Palace into an impregnable fortress.
They fought numerous brutal campaigns across the Sol System, including the Defence of the Solar System and the Battle of Pluto.
During the Siege of Terra, the Imperial Fists formed the backbone of the Loyalist defence. They held the walls of the Imperial Palace against overwhelming traitor forces for months in some of the most savage fighting of the entire war.
Rogal Dorn personally led many counter-attacks and duels, embodying the Legion’s unyielding spirit even as Terra burned around them.
The Imperial Fists represent unbreakable duty and stoic sacrifice. They are the ultimate defenders who will hold the line until the very end.
