Sons and Daughters
A loose collection of airship crews based in Colorado, most recently under the leadership of Tenzo Hasshin.
Originally a raiding organization, the Left Hands made their reputation of ruthless thieves and scavengers by first demanding supplies and resources as tribute, and collecting regularly until refused, then destroying and looting the offending community. Making a habit of leaving a handful of adults alive to witness the destruction made for a solid reputation, and fewer refusals in the future.
Lately, these crews have shifted to scavenging prewar tech, supplies and construction materials from abandoned cities, military installations and settlements. They pay a fee to Hasshin for the use of the reputation, and in exchange are afforded a wide berth by any but the bravest (or most foolhardy) of do-gooders.
