Caught between his grandfather's wishes for him to follow in his footsteps as a mechanic and his late father's legacy, Renton's only solace lies in surfing the Trapar waves that fill the sky.

As Renton joins Eureka in maintaining and piloting the Nirvash, he embarks on a journey that thrusts him into the heart of adventure and rebellion.
