Masteria Preview?

The man who had a dream that one day, there would be a city in Maple in which has many themes incorporated into it.
That man is Prose...

Although somewhat helpful, that's still kind of vague. I'm actually looking for an explanation of who he is xD

I gather he's a former member of Southperry who influenced the making of Masteria, but was not affiliated with Nexon? Or am I totally off the mark here? :f6:

Edit: OK, totally off the mark

Thanks for the info.
