Underground ghouls

The underground ghouls were a loose organization of disgruntled but peaceful ghouls in Necropolis

Background
Due to their unwillingness to partake in his hostile administration of the City of the Dead, they were forced by Set to live in the city's sewers. They were unarmed and posed no threat to anyone, serving as one of the most helpful factions in Necropolis, telling the Vault Dweller where to find the water chip but requesting him to fix the pump first.

Appearances
The underground ghouls only appear in Fallout.
