If Ray indeed was behind the whole summoning affair, it could explain a few things, like nobody knowing what to do with the heroes. And nobody really seeming to be responsible for managing them. But at the same time, it does beg the question why Ray himself didn't do anything. He arranged for them to be summoned, but then he just assumed they would automatically train their powers to the max and also fight amongst themselves to end up with only a few surviving individuals with all the skills, whom Ray could then use to restore his own sealed skills. That's helluva lot of assumptions and wishful thinking.
