Your cherished teddy bear. That intricate model kit you painstakingly assembled. The beloved picture book you read countless times. The gleaming stone you discovered in the park. What happens to all these childhood treasures as you grow older? In this tale, we encounter magical beings who collect these small items, left behind and forgotten by their owners as they transition into adulthood. These creatures quietly enter our world from another dimension, unseen by human eyes, and gather the abandoned “treasures” to take back to their realm. There, they use their collection to construct their own city, a whimsical place known as… Oblivion Island!
