Going to start with a couple of captions of Rend and Maim from the book Rise of the Horde after they had been prematurely aged for those interested in the topic but who haven’t read the novel:
Blackhand was in front, flanked by the three ogres. Behind him were his sons. Rend and Maim, who spoke to one another in low voices punctuated by the occasional rough giggle. Orgrim had been against allowing the boys to fight at first, but they had proven
to be stronger and better than one might think. They lacked their father’s cunning, but they certainly had inherited his bloodthirst.
Grisclda, too, had been trained to fight, but she was not a natural the way the bovs were. Their names were appropriate. Their father shot them an angry look and they sobered at once.
Orgrim wondered if Blackhand would make a speech. He hoped not. Blackhand was at his
He glanced over to see the ogres the Blackrocks had befriended talking to their kind. Or, rather, bellowing at them and occasionally smacking them. But at least the ogres had been distracted from following the retreating ores and appeared to be listening. One of them, bigger and wearing something that looked like an official sash of some sort, actually seemed to have a brain. Orgrim could not understand the vile things and used the pause to catch his breath and gulp some water.
“Can’t wait till we can kill them again,” Rend said. Orgrim glanced at his chieftain’s eldest son.
“If we succeed, they’ll be Fighting alongside us,” Orgrim replied. “You won’t be allowed to kill them.”
Maim spat. “Heh. Right. Kill 'cm on the sly.”
Orgrim grimaced. He himself would like nothing better, but… . “Several are dead already trying to make this plan of your father’s work- He wouldn’t like you undermining his efforts.”
Rend sneered at him. “Who’s going to tell him?”
“I will. If this works, and they listen to us—if any of them turn up dead, yours are the first names I’ll mention.” Rend glowered. Right now, he was so young that it looked like childish petulance, but inwardly. Orgrim was touched with
foreboding. He had never liked Blackhand. and liked his children, with the exception of little Grisclda. even less. He did not know if it was their parentage or their forced growth that was responsible, but there was a darkness in them that Orgrim mistrusted. One day, if they survived and began using their brains in addition to their powerful muscles. Rend and Maim would grow up to be
even more dangerous and deadly than their father.
“I told you he wouldn’t listen. Rend.” Maim said petulantly. “Old man’s forgotten what it’s like to have bloodlust running through him. Let’s go.”
With a final sneer. Rend followed his brother. Orgrim sighed. He had bigger problems than two upstart youngsters right now.
And a caption of the process itself:
Durotan forced himself to remain impassive while Kur’kul cast a spell on the five Frostwolf children. They writhed in pain, screaming and flailing on the earth as bones were stretched, as skin and muscle burst into unnatural growth. A sickly green line linked the children to the warlock, as if he was sucking the very life out of them. The expression on Kur’kul’s face was ecstatic. If the children were suffering, he most definitely was not. For an awful moment, Durotan feared the warlock would not stop at age twelve, but would continue draining life from the children until they were shriveled and ancient.
But thankfully, Kur’kul did stop. The young ores— children no longer—lay where they had dropped the instant the draining had begun. For long moments, they could not be roused, and when they did, they wept, softly, brcathily, as if they no strength left for anything else.
In the captions Blackhand’s children still act rather juvenile after being aged some years. In the book, only orc children between age 6 and 12 were aged to 12 when they’re considered old enough to fight. The orcs naturally mature much faster to adulthood than humans, so perhaps the mental difference wouldn’t be as stark as it could be if it were human children of age 6 matured to 18 or so. I imagine it takes a while for the children to mentally adjust to the world of adulthood as mental maturity comes with experience. As for twisting their mind for the worse, maybe, Orgrim seems to think that as a possibility at least.
I think you misrecall that part Tel
“Children begin training at age six,” Kur’kul continued. “They are strong enough to fight at age twelve. Summon all your younglings.”
“I do not understand,” Durotan said. “Summon them for what?”
Kur’kul sighed as if Durotan were a foolish child, “I have the ability to accentuate their growth,” he said. “We will. . . push them forward a bit. If we take all the children that are between six and twelve now and age them to twelve, we will increase the numbers of warriors on the field by almost fifty percent.”
