Thingamajig Confederacy

Now extinct, the Thingamajig Confederacy was an indigene faction composed of bands living along the Slapahoe river. They were mostly exterminated by Londrian browncoats led by Lord Randal Doohickey of Bembridge in an expedition in search of suitable territories for a trading outpost (settling what would later become Boarswallow).
The last surviving tribe, the Whatchamacallit tribe, under Chief Hootenanny, struck a peace accord with Lord Doohickey, selling the Boarswallow territory in exchange for some beads and pocket lint. The remaining Whatchamacallits interbred with Londrian settlers in Boarswallow, creating the modern Stink People.
