OK, I've decided. We're gonna do a variation on steampunk, clockpunk. Basically, everything's run on clockwork instead of steam, so we can set it around the Renaissance. I'm gonna be stealing a lot of Da Vinci's inventions to help get a feel for the kinds of technology at our characters' disposal. Another example fans of the Doctor will recognize.
Feel free to post any ideas you have, and I'll keep them in mind.
