How do NPC’s of a faction know one of the party members is a member of their faction? (careful: minor spoilers in question)


I’m currently running LMoP for 4 players. One of them has already joined the Lords’ Alliance, and I expect another to join the Emerald Enclave in the near future.

I’m planning to run SKT next, and have already started reading the book. The factions are mentioned quite often, and usually in a way that if one is a member of the faction they can get free lodgings/special items/a special quest.

I wonder though… how would they know they are part of their faction?

  • Would they be wearing a symbol on their clothes (such as a pin)?
  • Would they have to explicitly state to the NPC that they are a part of this faction?
  • Or would the NPCs simply be already informed about the new member and his/her appearance?

Any other possibilities?
