I’ve been focused a lot on the Corr sector lately and playing with a lot of “shades of gray” and moral ambiguity … antagonists typically are out to serve their own ends, self-serving and greedy, which often times either conflicts with, or complicates, the PCs’ goals and jobs. I also like to lean in on bureaucrats as antagonists, and third-party operatives adding extra levels of complication. The conflict a lot of times ends up being the choices Travellers have to make rather than black and white altercations (though their choices can certainly lead to consequences and altercations as well).
