A planet of two factions who in 2365 asked the renowned mediator Riva to negotiate an end to their civil war that had lasted 15 centuries; both sides — distinguished outwardly by only the hair color — had apparently fought so long they faced extinction.
Thanks to the efforts of Riva, the planet has stabilized to the point that freighters are able to conduct trading there by 2372, including Kasidy Yates' ship.
