The "Epsilon III" cargo transport is an alien transport of unknown class know to be used by the Caretakers of The Great Machine on Epsilon III.

In 2259, one such vessel delivered three time stabilizers to a Minbari cargo ship carrying Satai Rathenn and Entil'Zha Sinclair with Rangers Marcus Cole and Catherine Sakai while en route to Sector 14. The pilot stayed aboard the craft and was seen only by Satai Rathenn.[1]

Another, or possibly the same craft docked with the White Star 1 and delivered Zathras along with a shipment of equipment for a Time-jump system, along with personal time stabilizers, three Triluminaries and the Chrysalis Device.[2][3]
