In 2366, Marouk was approached by Captain Jean-Luc Picard of the United Federation of Planets when it was learned that the Gatherers, a band of nomadic Acamarian marauders, had raided a Federation outpost. The raids had made the sector, in which Acamar III resided, unsafe, with Federation research facilities destroyed and trade routes disrupted. Additionally, the Gatherers were expanding into other sectors.
After the captain was successful with his persuasion and convinced Marouk that reconciliation was possible, she met with Brull, a leader of a outpost on Gamma Hromi II, in an effort to complete the re-integration of Acamarian society.
With Brull as interlocutor and Picard of the Federation starship USS Enterprise-D as mediator, Chorgan and Marouk successfully negotiated an accord, but not before Marouk's servant, Yuta, attempted to kill Chorgan because of ancient clan rivalries. (TNG: "The Vengeance Factor")
