Toffia is a world almost, but not quite, based on Fairytales.
Fucking with Fairytales is so much a tradition of writing it occasionally depresses me that I couldn't think of anything more interesting to do.
There is only one published story set anywhere near Toffia itself, and that is known as "The Machine That Goes Ping":http://section.istic.net/TheMachinethatgoesPing, posted episodically to AFP in the first two weeks of September 2005.
