"I'm still not entirely at ease with only one first-generation Primaris Space Marine protecting you.
Once this batch of materials has been modified, have them remain at your side as guards and assistants.
Their 'former selves' were quite capable. After the modifications, they should better ensure your safety and help you handle some... research projects that require physical labor."
At his words, all the mechanical arms around Cawl paused slightly.
The Primarch had not only bestowed upon him the incomparably precious "Emperor's Revelation" technology.
He also placed such importance on Cawl's personal safety and the continuation of the Imperium's scientific endeavors that he had even specially tailored a guard force for him!
"My lord..."
Cawl's voice carried restrained excitement.
"Your trust and concern are my highest honor.
Please rest assured. I will immediately devote my full efforts to researching the integration of this technology with Servitor modification.
And regarding the comprehensive upgrade plan for the Primaris Space Marines..."
"I know. One week, right?"
Guilliman interrupted with a smile.
"As you say, my lord.
In one week, all your sons will be bathed in a brand-new, more perfect genetic legacy."
Cawl made the solemn promise.
"Very good. Go attend to your work, Sage Cawl."
Guilliman nodded.
Cawl bowed once more, then controlled his mechanical array as he departed, carrying the roll of silver foil and a mind full of fanatical research plans.
Like a rapidly moving research fortress, he hummed his way back into the depths of his unfathomable workshop.
Guilliman watched him leave, then summoned another person through the internal comms.
Before long, the Lord of Macragge, Chapter Master Calgar, entered the hall with ringing strides.
He came before Guilliman and dropped to one knee, his movement fluid and powerful.
"Father, you summoned me?"
His form of address was natural
