I'm not a suspicious person by nature, roll your stats in real life or on the dice roller of your choice then tell me. If you've got 18's across the board I might make you reroll but otherwise I trust people
I tend to run games off the cuff, I want primarily a role playing game, combat will factor in but I've never been much for puzzles.
I've never played or read Kingmaker, I was just reading the Mwangi Expanse source book and this idea came to me. Yes, though, you'll start out with a limited amount of supplies and a specific number of people. You'll need to shelter, feed, and protect them from the dangers of the jungle. They'll be useful in NPC ways, carpenters, cooks, foragers, maybe even a few guards but otherwise the party will be the ones responsible for their well being. Depending on how people go about things you may end up at war with one tribe or another, you may gain allies with the tribes instead, it all comes down to how you interact with them on first contact. The settlement will be a few days hike from the nearest civilization so the party and the settlers will be one their own.
You have to have been from Lantern, grew up there and have family and friend ties there, otherwise, what your character did in the mean time doesn't matter too much. If you want your character to have spent time somewhere else, picked up some exotic knowledge or fighting style, no problem. I'm not trying to limit people too much, but the story works best with everyone from the same place. I'm thinking Lantern is somewhere much further north, maybe in Virisia.
