Fall of Medusa V
Back to CampaignsThe Unification of Terra
Approximately 10,000 years ago, Terra (Earth) was a war-torn planet, divided into rival factions and nations. The Emperor of Mankind, a powerful psyker and warlord, emerged to unite the planet through conquest and diplomacy. He defeated the remaining factions and forged the Unification of Terra.
The Creation of the Space Marines:
The Emperor created the Space Marines, genetically-engineered transhuman warriors, to lead humanity's expansion into the galaxy. He designed 20 Primarchs, exceptional beings with enhanced strength, speed, and intelligence, to lead the Space Marine Legions.
The Great Crusade
With the Space Marines at the forefront, the Emperor launched the Great Crusade, expanding humanity's reach through the galaxy. The Imperium of Man was formally established, with the Emperor as its leader. The Imperium absorbed nearby planets and civilizations, incorporating them into the growing empire.
The Horus Heresy
However, the Imperium was soon torn apart by civil war. Horus, the Warmaster of the Luna Wolves Legion and the Emperor's most trusted general, turned against his master. Corrupted by Chaos, Horus led half of the Space Marine Legions in a rebellion against the Emperor. The Horus Heresy lasted for 9 years, devastating the Imperium and leaving it scarred.
The Siege of Terra
The Horus Heresy culminated in the Siege of Terra, where Horus and his traitor legions attacked the Imperial Palace. The Emperor confronted Horus, and after a fierce battle, the Emperor was mortally wounded, and Horus was killed.
Aftermath
The Imperium was forever changed by the Horus Heresy. The Emperor was left in a coma-like state, sustained by life-support machines. The Imperium was divided, and the Space Marines were reorganized into Chapters. The Age of Strife began, marked by constant war and strife.
