On the planet of Xylos, a world where giant, sentient trees govern the landscape, a young woman named Elara discovers a hidden grove where the trees are dying, victims of a mysterious disease. Elara, a protector of the forest and its inhabitants, embarks on a journey to uncover the cause of the disease, venturing into the heart of the Xylosian wilderness and facing the wrath of the ancient tree spirits who guard the grove. Along her journey, Elara encounters a reclusive clan of human-like beings who have been living in harmony with the trees for centuries. Together, they must unravel the mysteries of the disease and find a way to heal the dying grove, before the entire world of Xylos is consumed by the blight.
