Perturabo
Primarch of the IV Legion, Daemon Prince
Also known as The Lord of Iron
Homeworld: Olympia
Perturabo is primarch of the Iron Warriors, a siege-mind who felt unloved and made the galaxy pay for it. He could have been the Imperium’s greatest builder. He chose to be its greatest wrecker instead.
He razed Olympia after it rose against him, then followed Horus into heresy as the Warmaster’s engineer. He broke the walls of Terra piece by piece until Horus discarded him, and he walked away rather than die for someone else’s coronation.
Medrengard is his fortress-world in the Eye, a planet turned into a cage of iron. He has since taken the gifts of Chaos and become a daemon prince. The grudges are still the same. Only the walls have gotten stranger.
Ullanor seated him among the Warmaster’s court; Isstvan V and Phall taught the galaxy his method; Tallarn and Hydra Cordatus are the sieges that still name him; Olympia and Medrengard bookend the fall.
