The Mark Twain, named after the author of Life on the Mississippi, is the first vehicle able to Step across the Long Earth while carrying passengers and cargo.[1] Developped by the transEarth Institute, it served as a prototype for all the twains to come.


The Mark Twain's inflated body is plastered by the transEarth logo (a chesspiece knight) and below hangs a gondola with several decks that looks like an Art Deco fantasy.[1]

The Long Earth

In 2030, it was aboard this ship that Lobsang and Joshua Valienté (later joined by Sally Linsay) sailed during their journey across the Long Earth.[1]
