Okay this hasnt been thought through very well but its an idea i had for a story thats fkinda fantasy. basically its a mix between fantasy and sci fi. we have a prmitive planet with a medieval culture, many nations warring over differences, both geographical, religious and such, your average primitive cesspit. then for some reason or another (crash landing im thinking) a group of people from an advanced space faring culture end up on this planet. torn between not disturbing the balance on the planet and trying to find a way off it they end up venturing into the midst of all the conflict. And while some member try as they might to stay inconspicious to prevent unwanted consequences of their discovery, we have other members who decide they can use their intellectual ad technological advances to help them. (I.E. either pose as gods or form their own nations and such). its an idea that might be good i though.
