After overpowering and ordering those Saints, Lothur quickly saw them off in a southerly direction.
Watching them move, Lothur sighed, imagining that his men in Linn Province would soon be much stronger.
As for why he hadn't created new life forms to take the Soul Bones he had gathered here to Peters City instead of sending these people, that was because it wasn't easy to create life.
Lothur didn't want to send the two cats he was still observing. On the other hand, to create life, he needed something for the foundation of these beings. He needs to take life from other living beings along with part of their elemental affinities to create new possibilities.
In short, he couldn't create life from nothing, even with his ability. Something would always need to be provided, like an initial push necessary for a cyclical movement to begin.
