During the close of the Four Years War between the Federation and the Klingon Empire, Starfleet occupied those Orion Colonies formerly held by the Klingons, in a period Orions knew as the Year of Horror. Among those worlds was Hartha. There the Federation placed restrictions on commerce that the Orions found intolerable. These new rules were supported by a military presence that the Orions could not resist.
In response, in reference stardate 1/9805, Arthas Liktor the Bold left Hartha to run through the Federation front lines aboard a modified courier. He went to the Orion homeworld of Botchok (Rigel VIII) to warn of the tightening Federation grasp, but was imprisoned by Botchok Planetary Congress to stop him talking.
