The Boy from the West and the Knight of the Blue Storm

Every few decades, a troop of equestrian fae knights known as the Wild Hunt rises and wanders the land, displacing long-dead vegetation with sprouting new ones.

Gabriel, a restless little kid with asthma, meets Chise, a magically gifted girl, and Elias, an enigmatic mage. He yearns for adventure and finds a broken rock left by the group of Wild Hunts, eventually calling forth the knight inside.

As Gabriel becomes entangled in their world, he discovers perils and unknown mysteries. The guide must find his horse and bag before his absence causes irreversible harm since the only recollection he has left is the desire to return.
