I think one of them is considered the league champion, I could be wrong about that.

I have heard that rumor and I am a bit inclined to believe it if only because the driving force of this world seems to be the Pokemon themselves. Everyone here is stripped of any abilities they have upon arriving but Pokemon have abilities that you wouldn't expect a creature to have. There may still be some information worth getting from the Elite members but I have a feeling they might not have what we're looking for.

I was told that sometimes professors from other regions visit and they may have information worth getting but I haven't run into any of them myself.
