Iceland is a land of legends and magic, where some people still believe in magical creatures... Eighteen years ago, a war broke out here between dark and light elves. The dark elves did not want to retreat until Yggdrasil - the tree of life - disappeared from the face of the earth. After the war, the heart of Yggdrasil was stolen, and every year the days in Iceland became shorter and darker, gradually plunging the world of people into darkness. Every living creature tried to convey the terrible news to humanity, praying for salvation, but people were blind to all the signs. Only Faye, who always loved nature, noticed the strange behavior of the fireflies. It was they who led her to the clearing where she discovered the dying tree of life. Together with Aron, her lover, Faye decides to save Yggdrasil. Now the fate of two worlds depends only on her. Will the girl be able to protect them and not lose Aron forever? Or is all living things destined to drown in darkness?
