Roboute Guilliman: Primarch of the Ultramarines

His critics — and among his brothers they were many — called him a bureaucrat with a sword. I knew the man. The sneer confuses the tool with the mind that wields it.

The Battle King’s Son

He fell to Macragge, and fortune fell with him: he was found and adopted by Konor, one of Macragge’s Battle Kings. The boy ran the freezing mountains of Hera until they could not tire him, and fought bandit campaigns in untamed Illyrium at the Battle King’s side. When treachery took Konor, Macragge took Guilliman as its ruler — and prospered as no world of that age prospered.

The Builder of Five Hundred Worlds

Given the Thirteenth Legion, he did the thing no other primarch quite grasped: he treated victory as the beginning of the work. Where other Legions left smoking compliance behind them, Guilliman left functioning worlds — fed, ordered, governed, loyal — until five hundred of them turned about Macragge like a wheel. His Ultramarines marched in royal blue and gold in Chapters ten thousand strong, and in the tactical simulations he loved he kept a private list — his dauntless few, Dorn and Russ and Sanguinius and Ferrus — the brothers who, paired with his own Legion, could win any war in the galaxy.

They mocked the man who wrote everything down. Ten thousand years later, his book is almost all that still works. I permit myself the irony.
