Being not involved. Keeping their heads down. Trying not to be noticed. There are thousands of people in the Saltmarsh area, and maybe a dozen of them are named.You do realize you're saying the same thing I did. Ghosts of Saltmarsh does not have a SINGLE halfling NPC. If they are common in the area, WHERE ARE THEY?
But it's irrelevant. Number of halflings in the area has no effect on player character halflings. The PC can be the only halfling on the planet. It doesn't matter.
