While the headquarters of the White Fang may be in Menagerie, their one of their side branches is located in the city of Mantle. The soldiers they have sent to Atlas are known for their guerrilla tactics and their ability to turn citizens against their own nation. Their designated leader is a specialist in this type of political warfare. They are a genius faunus that is known to lead cities to implode on themselves.

Over the years, their influence in Mantle has increased significantly. Their tactics have earned them residence within Mantle and has effectively turned most of the city against Atlas, albeit secretly. In a way, the entire city seems to be a secondary branch of the White Fang due to its harsh treatment and poor economic situation.
