So, question for the GM; what roll would I need to make in order to know why this alien race might be in the ship? EG, to figure out if Val knows who the ship was fighting when it went down, how unusual this aliens presence is, what it might imply about what might be on the ship, what the Vesk are looking for, etc etc? In Pathfinder, I'd be rolling Knowledge History for the first question and possible Knowledge Local or something for the species traits and temperament and whatnot. Would that all fall under a Culture roll in Starfinder? Or would you want a different skill being used? :-)
