There was a slight thought in Zain's mind when he had received the system, that perhaps there was a goal behind it, something that it wanted him to do. Now that he had met the creator, he thought that she might know what that goal was.
Or perhaps there was a large server-like machine where she could input the quests into it, and it would direct him where he was going. Yet in the end, after meeting one of the creators, he seemed quite disappointed by the answer.
Still, he couldn't shake off this feeling that the system maybe had grown beyond what the creators had intended and it had its own purposes, because why would it show him visions of the past, of the lives of the creators. On top of that, why would it tell him to meet the two creators of the whole zombie mess in the first place.
It was almost as if the system wanted him to learn the truth.
