Star Trek: The Next Generation/Recap/S1/E05 Where No One Has Gone Before

Warp efficiency tests send the Enterprise traveling far beyond known space, where the crew's imagination takes on real form. First appearance of Eric Menyuk as The Traveler.

This episode contains the following tropes:

 * Character Shilling: The Traveller goes out of his way to tell everyone how how super-duper-awesome Wesley Crusher is.
 * Readings Are Off the Scale: The Enterprise passes Warp 10. Later Jossed by one of the technical manuals.
 * Your Mind Makes It Real: Anything the Enterprise crew can envision, becomes reality. This includes such things as flashbacks, very real dangers like fire, and ultimately, getting the ship back to its own galaxy.
