New Campaign in the making - D&D Fantasy, meets Jules Verne, meets Atlantis

 I've had this idea running through my head...actually, a bunch of ideas running through my head and I just wasn't sure how to put them altogether...until an epiphany hit my lack of sleep state mind. 

I've played a lot of video games, board games, I've read a lot of fantasy and science-fiction books and something I wanted to try and do was find a way to merge science fiction, steam punk and fantasy. 

I'm not sure yet if this will be an adventure that starts out at level 1, or this is an adventure something much more experienced.
