Silverton

Silverton is a small town to north west of Broken hill predating the Warlord's Silver Town settlement (formerly South Broken Hill). It is a source of many raiders and resists the warlords power. The remnants of a small town that always looked like wasteland compounds and home of the Mad Max museum, a famous treasure trove that is a holy place to raiders and wasteland scum. They are led by Mortis, master of the wasteland, a former bunker trained military man who has many allied gangs in the Broken Hill ruins.

Raiders seek prisoners for slaves or meat, children to indoctrinate, grain for bread and beer, vehicles and machine parts plus weapons.

Any attacks on the town must face aircraft scouts and vehicles. As the warlord's warriors lack enough transport and have failed before due to aircraft they await the right condition, especially weather that might ground ultralights.

Adventurers might be recruited to infiltrate, raid by night or kidnap someone for intelligence or assassinate Mortis. Getting the Water Boys or or Flyers to leave could cripple the town.

They often open the town to race events a good chance to visit not as a enemy.
