Oh dear! That is a strange sentence! Can you provide a bit more of the context around the sentence please? Like, what is it about?!
I think, and this is just a guess, that this person created a personality which was against the norm. Evoked mass of feckless educational n'er do wells sounds almost like it's a group of academics and the author is suggesting that they are reckless...! If you could provide a bit more info though then I may be able to have more of a stab at guessing! Is this an autobiography of someone? It sounds like the author is suggesting the person arose to be great or something despite the climate they were in!
I hope I haven't confused you any more!
