There are two parallel worlds in this world - the "Light Realm" and the "Shadow Realm". The light realm is the real world where humans live, where technology and magic coexist weakly; the shadow realm is the forgotten ancient world, full of broken memories, sleeping mythical creatures, and an energy called "stardust" (which can weave reality and repair memories).
The two worlds are separated by the "Sea of Oblivion", with countless "memory fragments" floating on the sea. Only the selected "Weavers" can travel through the stardust.
Lin Ye, 17 years old, is the diary writer of an ordinary high school student in Guangyu. On the surface, he is introverted, but in fact he is extremely sensitive to "forgotten things" - he can see the vague images left by old things (such as figures in old photos, handwriting in old books). He didn't know that he was the last descendant of the Weavers, and that his stardust abilities were sealed by his family in an ancestral book.
