I am creating an adventure based on a navigator house and I want ideas/help. The basic story is that mysterious happenings and deaths have been happening in a very affluent section of a noble/pleasure world. It turns out that two navigator houses are having issues with each other. One house is has raided the dungeon of another, where failed genetic experiments, older family members who are no longer able to work or be in public from prolonged exposure to the warp, and the "still born" family members/monsters. The raiders have lost several of their captures and want them back. While the original house can not let these embarrassments be found out about or their trade secrets get out want the escaped and captured dead. And a third house wants to expose them so they loose face (and contracts).
So basically the characters are thrown into a three way war. With two houses wanting it kept quite and a third trying to find out about it and expose it. The players can stay neutral or get on a houses side, or try to work with the other nobles that want the deaths to stop.
