Tempest-tossed civs start with half the population? That's probably an insurmountable disadvantage right there, especially since it takes a fixed amount of food to increase population, so increasing population gets easier, not harder, as long as you've got more decent terrain to work. (Speaking of which, we need to know what the terrain does, and what our existing techs do.) And it's even worse, because all of them but Luke Prowler start with what appear to be food-boosting terrain improvements. And starting populations this low make the native civs' early game advantages even more pronounced - with no real ability to research for at least the first ten turns or so (other than my mad scientist), it'll take us forever to catch up to even the Taharks' technological prowess, completely negating our only real advantage. Plus, if anything of note happens in the first ten turns or so, it'll be the tempest-tossed civs getting destroyed. If this is the starting setup, I'm seriously not sure I want to play.
About my setup:
Is Dignity supposed to increase or decrease the labor I have to put into working the land? The former seems more likely, but the way you've worded it, I can't tell. And if it increases the labor I need, does that mean I can only work one hex to start?
I don't think Zeal exactly makes sense. My people are wildly enthusiastic about pretty much everything they do, and if anything they're less zealous about military service.
About the different types of terrain: I'm not sure what they do, obviously, but I can't help but notice that the swamps around Luke Prowler's city are the only actual biome; everything else seems pretty sterile. Does this translate into a massive food advantage? And are those black lines food-increasing river analogues? If so, Nevyn will probably be unstoppable, except by Luke.
