Lost Heritage was a criminal gang of the late 24th century.
The gang was led by an Orion man called Stavan. All members of Lost Heritage had illegal genetic modifications, which were performed at an Orion-controlled planetoid somewhere near the Rigel system.
Lost Heritage battled with the Orion Syndicate several times, with the potential to break out into a war for territory. (Last Unicorn RPG module: Star Trek: Deep Space Nine Core Game Book)
