Luna's clock has one minute left. The woman repairing Elara's clock tells her the ink feeds on forgotten stories, and the only way to stop it is to give it a story it cannot digest—a true story, one the ink has never tasted. Luna must choose which story to tell: her own, Elara's, or the library's. The scarred other Luna offers to trade her story for Luna's life. Luna descends further into the library's foundation, where she finds a room lined with mirrors that show not reflections but memories—each one a real event the ink has stolen. She walks through them, tasting each memory, and realizes the ink is not a curse but a parasite that has been feeding on the library's keepers for centuries. The woman who was once a library appears in one of the mirrors, not dead but dying, and she whispers the only story that can break the cycle: the true name of the ink itself. The episode ends with Luna speaking that name into the dark, and the library begins to scream.
