User blog comment:Strawhat1/Ra's Al Ghul: Realism VS. Comic Book Version/@comment-807326-20140804130113

Ra's seems to be the be-all and end-all of the League. Like, without him it probably wouldn't have existed. So for him to be 50-60, it seems weird to have this legendarily mysterious organisation that's like 30-40 years, tops.

I think they won't explicitly say it, but Ra's will probably remain pretty mysterious throughout his run, even with what is revealed!
