Formerly "Under a Willow Tree" Kili Fanfic Arenna is the only sprite to live in Middle Earth. She spends her time watching over the lands, passing over them like so many scattered leaves in the wind. However, her inconstant life is interrupted with a visit from an old friend, Gandalf the Grey. He persuades her to aid the company of Thorin Oakenshield. Arenna embarks on this perilous quest in the hopes of learning more about the darkness that plagues Middle Earth. But this restless soul finds something much more dangerous, something worth holding onto.
