The Goodwins start their journey home to Brise Soleil as Sam challenges Boden and Magnus with the truths of Elyon, encouraging a new path. But after experiencing the power of the mysterious, sunstone-powered engine, Boden is consumed by another mission.

The Gearlock Train embarks on its first voyage south to Barrents, to be christened by the Goodwin family. Obsessed with the mystery of the coin and sunstone, Boden, Magnus, Cy and Reggie experience a christening of their own, awakening a power unseen by anyone in the Beyond.

Listening posts across the Beyond are packed as residents continue to honor Roy through music and comedy. In Serac, Camden confronts a new problem that points to an old nemesis and in Barrents, a mysterious calling beckons Boden, Magnus, Cy and Reggie.

Days of celebration commence in honor of the fallen patriarch. A special creation looks to connect the vast regions of the Beyond and Cwrig has a new “friend”, disrupting the fragile peace created by Elyon.

Residents of the Beyond return to the Well for the memorial. Boden and Magnus are consumed by the origin of the coin as other questions remain concerning a new stone and the cause of Roy’s death.

Twenty years have passed since Cwrig’s isolation and exile. Those who escaped the destruction of Salvation now call the Beyond home. It is a time of peace and discovery, for both creatives and craftsmen.
