Shadows Of The Old Camp

secretive spies and assassins working for Ore Barons
their headquarters are in the dungeons of Old Camp Castle
for obvious reasons they are unlikely to wear easily recognizable uniforms and may even pretend to be members of other factions
in the final release of the game they are no longer spies, assassins nor secretive, and instead are more like simply a lower rank of the Old Camp Guard and consistently wear red armors
The Invisible Man is their leader (design doc NPCs per Guild)
