I'd be interested in helping out, but I cant seem to get to your e-mail, mine is ItsWarren@hotmail.com, feel free to e-mail if there is something I can help with.
I also have a concept. One which would allow us to move it into any setting and have a series of contiguous semi-related concepts that would each be portable to several other games or settings.
I have been working on a project that I have been calling Time Crisis. The basic premise is that in the future, time travel has become very prevelant, but a side effect of it is that "temporal distortion fields" are begining to cause creatures and people from various ages to cross into other eras. I have been working on it from a d20 Modern perspective and with that premise, I have created several new starting occupations (a few for each of the major eras and a few that are available to all eras). This concept should provide enough flexibility to allow cross-setting adventures, as well as several linked adventures.
