The Kaen'anti Bypass, named after Kaen Tan, is a trade route that was used mostly by the Romulans in their trade with the Lorundans. The Bypass was a shortcut of the longer K'tem hyperlane. However the Bypass was much more heavily traveled than the segment of the K'tem that it bypassed, and was considered to be part of that trade route.
The route originated at Lorunda before splitting with the K'tem, and crossed through the Par'tha Expanse, on the way passing worlds such as Zalenaedere, Nanaria, Aelann, (where it intersected the Siiden Passage and the Oscion Shipping Lane), Miralon, Calavar, Kala'din and Tinall before rejoining the route. The trade through this part of the Expanse poured credits and influence into the coffers of the periphery worlds, and eventually led to their independence. The periphery became known as the Freeworlds Region. The retreat of the Romulans decades ago also hit the Freeworlds Region hard. The Kaen'anti Bypass was no longer being used, and trade and the economy took a huge dive.
