In Steampunk world, I would be Clementine Blair, a Steampunk Punk Rocker.
 
I would come from a middle-class family and go to an all girls-college on a scholarship (not a far stretch). Halfway through the year I would get kicked out for corrupting several of the other girls and persuading them to participate in "gang activity". No matter though, for Clementine Blair stops for no man.
 
So, I took my gang of dangerous, scandalous girls, and opened a cafe-slash-saloon that caters to the seediest creatures of the town. The cafe's hours are sporadic so that Venom (Henrietta Johnson), Absinthe (Gertrude Albion), and I can follow our favorite musician, Thaddeus Ramone, early punk-rock violinist, on his tour.
