Saruwen Station seen from above. Note the Class-D Cargo Containers floating in space bottom right of picture.Xizor Cargo Containers were a series of various-sized freight containers designed to store cargo during transit in space. Manufactured as part of a series of standardized storage units by Xizor Transport Systems, they could be loaded onto a wide variety of transports and freighters. XTS containers were specially designed to protect their cargo against the rigors of space travel, but were also a cheap and useful place to store cargo outside a space station, instead of occupying valuable pressurized volume inside. Thus, many storage depots had clusters of cargo containers floating in space nearby.
