The underhives are often the battlegrounds of the proxy wars fought in the names of the Clan Houses, gangs made of the young doing their time before returning uphive to serve their families if they live long enough…
The six pre-eminent Clan Houses are House Cawdor, House Escher, House Goliath, House Van Saar, House Orlock and House Delaque. Many lesser clans exist across the hives of Necromunda, but none are as powerful as these six. Many are in effect feudal subjects of a House, but others might be outcasts or upstarts. Each of the Clan Houses is master to countless subservient gangs, the fighters serving as the disposable foot soldiers in the endless proxy wars fought in the darkness of the underhives, allowing the Clan Houses to continue business with one another with a semblance of civility in the spires above.
Necromunda: Underhive contains two pre-made gangs, the Ironlords and the Carrion Queens, but the rules also allow players to found their own gangs.
The first step in founding a gang is deciding which House the gang is drawn from. The rules in the box cover House Goliath and House Escher, and future supplements will cover the fighters and equipment for other gangs (as well as hired guns and other additions to a gang).
The next step is to choose the fighters that make up the gang. Both Goliath and Escher gangs must include one Leader, can have up to two Champions and must have at least three Gangers.
