Marius and his fluffy, six-legged co-pilot, Whisk, love exploring the galaxy in their trusty ship, the Star-Skipper. But their latest mission goes terribly wrong when a swirling vortex yanks them out of space and sends them crashing onto Xylos a planet where the storms never stop. Stranded in a world of endless drizzle, whispering gales, and ground-shaking thunder, Marius and Whisk must find a way to repair their ship. Their adventure begins when they meet the Aerians, shy, furry creatures who live in magical villages built high in the giant, indigo trees.

With the help of their new friend, Rika, Marius must brave this wondrous and dangerous land. Their quest for rare Sun-Crystals will lead them up the jagged, crackling slopes of Lightning Peak, through a forest of echoing stones, and high into the sky to a breathtaking Cloud City that floats above the chaos. But the planet's greatest challenge is yet to come: the Never-Ending Night-Storm. To survive the terrifying darkness and find the mysterious Weather-Stone needed to guide their ship, Marius will have to face a cyclone maze and a sudden, stinging sleet.

Join Marius and Whisk on a thrilling journey filled with glowing moss compasses, giant Bolt-Catching creatures, and a heart-pounding race through the Howling Hills. Will they gather the parts they need, fix the Star-Skipper, and find their way home through the haze?
