4. I disagree with this. The background traits are just that, backgrounds. The devs are going to add in an event system and other ways to gain/lose other traits, but background traits define who the base character is.
Indeed. What Kanoe808 is refering to are not classes (there are no classes in the game other than those imposed by the player) but backgrounds, describing a character’s upbringing and their life before joining the company. Even though characters will effectively become mercenaries by occupation the moment you hire them, that doesn’t change the fact that they’ve been a farmhand or a beggar for most of their life, which obviously has a profound impact on what kind of man (or woman, eventually) they are now and will continue to be for the rest of their lives. Some backgrounds can in fact change with events, but only to extend the original background (e.g. a monk taking up a more radical interpretation of their faith).
