Writing Legend of the Emerald Knight

I am writing a convention game for Battle for Oz called Legend of the Emerald Knight. I ran the first iteration at MACE West 2015 and it went OK but I do need to change some things. The second version of this adventure is currently under development and will hopefully be run at ConGregate 2015.
The inspiration comes from the one aspect I love about the setting – the mixture of real world “Outsiders” and the fantasy elements. Never a purest in the fantasy genre, I have always loved mixing things into fantasy. Steampunk is a good example.
