They are a wandering gang, displaced from their homes by the rise of Silas and his Las Cruces gang. Now the Desaparecidos, the "disappeared ones" live in shacks on the margins of El Sumidero, the city's giant outdoor sewer. In a city that can seem like Hell, this is a double Hell, and they are not happy. If the other gang leaders of Scare City are going to take on Silas, they'll need soldiers, and recruiting the Desaparecidos would be a good start.
