Theron went through each and every one of the Soul Lamps. He didn't do much in the way of introducing himself, but it was easy enough for them all to come to the same conclusion that Uslim did.
He learned their names, their origins, and he began to piece together a convoluted image of what Patriarch Nightingale wanted.
As far as Theron could tell, not only were many of the missions Patriarch Nightingale sent them on red herrings, but maybe the people he controlled themselves were as well.
There didn't seem to be any rhyme or reason to their locations. But… Theron wasn't 100% sure of that conclusion either.
This was because for someone as weak as Patriarch Nightingale to control so many powerhouses, he had no choice but to target them as youths and children.
Unless the Patriarch was a God, there was no way he'd be able to predict things that far into the future. In the future, Theron would have to question them more thoroughly about where they originated and their life stories.
