Transport's outer skin can form messages in Vorlon
Vorlon Technology is the name given to a type of Organic Technology developed and used by the Vorlons.
After they departed the galaxy in 2261, all that remained of their technology was what they had given to the Minbari in the development of the White Star class ships, along with a single transport left behind on Babylon 5, whatever remained within the sealed borders of Vorlon space and the Vorlon Homeworld.[1]
The Minbari, later, shared the technology they knew with the Interstellar Alliance and, indirectly, Earthforce, to create the Destroyer class White Star.[2]
