The Hume Liberation Front, or HLF, was a separatist movement in the Hume System of the Silesian Confederacy. In the early 18th Century PD, they issued "letters of marque" commissioning "privateers" to prey on Silesian commerce. These privateers soon turned to piracy, disrupting the Star Kingdom of Manticore's commerce as well, prompting Manticoran military intervention in Hume. (Companion)
