Luna stands in the room where a shadow wearing her face writes the first story. The shadow offers her the pen, saying the story is on its final page. Luna must decide whether to write the last word or let the shadow finish it. She reaches for the pen, but as her fingers close around it, she feels the ink surge into her hand, rewriting her memories. The shadow smiles with hollow eyes and whispers that the ending was always hers — but not the one she chose. Luna pulls her hand back, leaving the pen in the shadow's grasp, and the room begins to dissolve. She runs through corridors that shift and collapse, chasing a voice that sounds like her own. The voice leads her to a door she has never seen before, carved with symbols that glow like silver ink. Opening it, she finds a room full of books that contain every librarian's true name. She searches for her own, but the shelf where it should be is empty. The hollow-eyed woman appears, not as a shadow but as a person, and tells Luna that her name was never written — it was stolen before the story began. Luna asks who stole it, and the woman points to the shadow, which now stands at the door holding the pen. The episode ends with the shadow stepping into the room, the pen dripping silver ink, and Luna knowing that if she takes it, she will lose herself forever. But if she doesn't, the shadow will write her ending for her.
