He returned to Terra to begin to reorganise his empire into a unified whole. The first to be found was Horus, who would become the most trusted 'son', second only to the Emperor.Įventually, the Great Crusade reached a point where the Emperor felt that his Primarchs could continue without him. His homeworld would also become the new homebase of the Space Marine Legion in question. Upon discovery the single primarch would be evaluated, and if found worthy - all of them were - received the command of his respective legion. This created twenty distinct Space Marines Legions which he led into the Great Crusade.ĭuring the Great Crusade, the Emperor, sensing that the primarchs were still alive, searched and eventually found his 'sons', one by one. In the creation of a particular legion he only used the material of a single Primarch. However not everything was lost, and using samples collected previously from the Primarchs the Emperor was able to create Space Marines.

Unable to destroy them, they still were able to scatter the Primarchs throughout the galaxy. However while the foetal Primarchs where still maturating inside of womb-vats, the Chaos Gods somehow managed to spirit them away. Even the Emperor could not be everywhere at the same time, and accordingly he created twenty Primarchs using his own DNA.
