In Babylon 5, the Shadows used what looks like a completely different system for interstellar travel compared to the other species. While almost every species required either jump gates or creating a jump point (even some of the ancients), the Shadows seemed to just fade into space. When leaving a particular region, they would just fade out and appear in hyperspace.
The Babylon Project describes the Shadows as being able to "phase directly into hyperspace". It's not clear to me where the Babylon Project got that description from (I couldn't find it in the referenced Babylon 5 roleplaying sourcebook). I'm curious if JMS ever discussed it, or if it was mentioned in one of the episodes or books.
