While the Cortex system isn’t necessarily designed to be as collaborative as, say, our Dresden game was, since we’re making up the setting from scratch I figure it wouldn’t hurt to get feedback on what I’m already planning and incorporate other ideas!
Also I’m linking to plenty of Steampunk inspirational sites to get you thinking about what could be possible in this world – but feel free to let your imagination run wild.
Need more information on the Supernatural show? There’s a wiki for that too
After that, take a look at your wiki. There is some more helpful info there.
