Not long afterward, the massive joint fleet temporarily returned to Macragge.
Regent Guilliman immediately gathered a large number of Astartes successor chapters and countless common citizens to hold an exceptionally grand investiture ceremony for his Primarch Brother, Rorschach.
Amid the cheers and shouts of countless Astartes and common citizens,
Rorschach formally became the Regent of the Dark recorded by the Imperium of Man.
For the first time, the Lost Primarch stepped onto the Imperium's political stage.
However, given Rorschach's temperament, he would never treat those vermin with the same cordiality as Guilliman did.
Therefore, Rorschach also hoped that those blind Imperium factions would not provoke him. Otherwise, rivers of blood would no longer be a figure of speech.
After the investiture ceremony ended,
Rorschach revealed his plans to prepare for the Disaster Crusade to Guilliman.
However, he did not tell him all the specifics.
Guilliman did not immediately object.
Instead, he personally helped Rorschach formulate various war plans for facing countless different battlefields.
However, Guilliman also advised Rorschach to remain on Macragge for a while longer before launching the Disaster Crusade.
That would also give the people of Ultramar and the Astartes more time to rest and recover.
Thus, Rorschach and Fulgrim joined forces with Calgar, Chapter Master of the Ultramarines Chapter, and numerous successor chapters to launch one reclamation campaign after another across the rest of Ultramar under the pretext of unit integration.
After bidding farewell to his Primarch Brothers one by one, Regent Guilliman also set off on the long journey toward the next stage of the Indomitus Crusade.
After Regent Guilliman left Ultramar,
Rorschach, as Regent of the Dark, became Ultramar's uncrowned king.
However, he did not act recklessly. Instead, he followed a sacred tome of governance Guilliman had left behind and began making further attempts.
