From the 1997 book The Great Kettles: A Tale of Time page 30.

In an effort to make his way back home after he traveled through time to The Great Kettles, Joey found Mother Nature. She traveled in an elegant boat with a trail of flowers - the Wooden Swan. Mother Nature told Joey that "The right path is never clear, but the journey is always a journey forward, never back." Then she gave Joey a tiny lantern to guide him home. - Dean Morrissey
