Recently I have been expanding on The Pit , I have made several npcs for it however I'd like to go further. I would like to flesh out a culture of not just the Pit but rather the very lowest "habitable" levels of Coruscant, but I'm some what at a loss on how to do it. I suppose I could use the npc's again, however I don't know if the Group Template would be suitable, as while they might share same cultural traits, they certainly wouldn't share the same loyalties or goals. Perhaps I could do it under lore, which may gave me more freedom? Yet I feel like I'd run into the very much the same problems.
So my question is, should I use the means I've just suggested, find another way or simply not bother?
