The Complete Rise and Fall of Roboute Guilliman | Warhammer 40K Lore Documentary

This video tells the full story of the XIII Legion's gene father, from his adoption on Macragge, through the fires of the Horus Heresy, to his return in the 42nd Millennium. Of all twenty Primarchs, Guilliman landed in one of the few places that didn't try to kill him. Raised by the statesman Konor Guilliman and the brilliant adviser Tarasha Euten, he received what nearly none of his brothers ever had. A balanced upbringing rooted in both leadership and empathy. We cover how he built the Ultramarines into a force of over 250,000 warriors across five hundred worlds. The devastating betrayal at Calth. The founding of Imperium Secundus. The creation of the Codex Astartes and the near civil war with Rogal Dorn. The duel at Thessala that froze him for ten thousand years. His resurrection. The Indomitus Crusade. The Plague Wars against Mortarion. And the devastating truth he discovered on the Golden Throne. Whether you are new to Warhammer 40K or a longtime fan, this video brings together every key source into one complete narrative. SOURCES AND FURTHER READING: Horus Heresy Era: 1.
