Rungboy

A low-ranking member of a criminal organisation, especially the Castillian Mafia. These are people who don't do much illegal, but are "on the first rung" of the ladder that leads up to Family Soldiers and Safe Men. Usually, they have contact with someone they know to be involved with a major family, and might be called upon to perform some favour (like leaving a door open at their place of work, or helping the family source building materials for a new extension).
