Above the sea of clouds, countless islands are scattered like stars, connected by a long river in the sky called the "Ether Route".
The black-haired silver-eyed elf named Misselia, with her inherent alienation and rationality, bid farewell to her traditional hometown "Emerald Cradle" and embarked on a lonely wandering journey. What she is looking for is not the pinnacle of power, but to find a real shelter for her tired soul in this vast sky.
The memory of her past life allows her to remain a calm observer of the world, and her innate unique talent of returning everything to its origin has become her greatest reliance on moving forward alone. She doesn't need heavy luggage. Everything she needs on the journey comes from her unique "decomposition" and understanding of the world.
Riding the airflow of the etheric route, her footsteps will traverse the "City of Thousand Sails", a human city where magic technology thrives, go deep into the "Molten Core" of the volcano where the dwarves are entrenched, and even touch the "Big Beast Skeleton" where the orcs roar. During the journey, she will witness with her own eyes the conflict between nature and technology, and the opposition between tradition and innovation.
This is not a tale of a hero's rise. This is a story of a soul relearning how to get along with the world under the endless sky. A long journey of finding, seeing and understanding is slowly beginning.
