The basic six slots for the smaller pyramid and then some background free slots (So slot or gift per chapter in their life.) Everyone can attempt to do things that are humanly possible, so a lot of people can be "effectively average" with the default mod +1 MOD. Like Castle Falkenstein, you are okay at everyting (except thing that require specialty skills or intense training).I think it covers most genres. Some settings might require special skills, but that's to be expected with most systems and I wouldn't worry about it right now. It's a bit on the complex side in terms of the number of skills and how specific they are, but I think it works.
I was also starting a character off with one flaw required. Thus they will have a gift as well. I do have a thought about dropping one skill as specifically "poor" or -1 MOD as an option for that flaw.
One of my primary genres of play is Urban Fantasy/ Occult Adventure (the other two are Super Heroes and Nipponese Fantasy). This is a skill I always have to shoehorn in to every system. It also works for "Martial Arts Secret Society", when I am doing a martial arts oriented campaigns.One thing, though. I absolutely love your concept of "Shadow Society" as a skill equivalent to Streetwise, but focused on the occult. That's a really, really awesome idea.
