Have you though about how many the secondary characters are going to be? The air ship crew (b.t.w. is it a blimp or a zeppelin or something else?) (of which, at least, the maid, butler, captain, first mate, and the cook should be named) should at least be 20 hands big and that not counting the doctor and/or nurses that is helping the countess.

Also from have you decided from which country your Byronic heroine comes from?
