The Erehwon (UESC-190484) was a Class 3 Heavy Cruiser belonging to the United Earth Colonisation Team, aboard which a population of humans evacuated Earth to form a new colony. It had at least four decks.
While the majority of the colonists slept aboard the Erehwon, their new city was built around the ship by the Vardy. (TV: Smile)

Erehwon is "nowhere" spelled backwards.
