If I make a character that is a medic to all three factions (sort of doctors without borders kind of organization) what will it be classified as?
Technically that’d be an outsider! If they’re not a medic strictly to one faction, then they don’t fully belong in any. For example: The Alliance sees anyone not strictly affiliated with them as illegal/unlawful. Aka, not part of the Alliance = outsider or rebel. If you choose to treat those that the Alliance sees as unlawful, then you yourself will be seen as unlawful.
