Luna is an Erelan keeper-a magic user with power over nature. With only her intuition and her purpose to drive her, she travels from world to world, correcting the balance of nature and helping life to thrive. She does this, as all keepers do, through a world's natural essence, more commonly known as the �ther. During her travels, she arrives on the small moon of New Kiplar, a reclaimed Terran colony world deep within the actively contested Huk'Va system. However, not all is as it seems. Something powerful is leaking magic into the �ther, sending ripples of dangerous, magical radiation across the globe. Concerned with what she encounters in the �ther, Luna takes it upon herself to find the source of the magic-and stop the devastation it has wrought.
