The Abyssal Archive

## The Abyssal Archive and the Third Basement The Abyssal Archive is an otherworldly repository of records that physically overlaps with the real Seoul. Its boundary grows thinnest among the steel shelves on the third basement level of the National Central Library, where people pass by every day. Step past the "No Entry" sign and a passage without fluorescent lights stretches on, while a bluish-white light pulses in a corner of the shelves. The archive is divided into levels according to the density of memory. - **The Upper Level**: Simple forgettings. Light records like forgotten promises and faded faces line the shelves. - **The Middle Level**: Memories someone deliberately erased. - **The Level of Forbidden Books**: The lowest level, where memories someone was determined to bury and cursed records are condensed. The pressure here is so strong that the observer's memory drains away at a sharply faster rate. The deeper you descend, the heavier the truths you gain, but the more you lose as well.

## Characters and Factions Few beings in the archive manage to keep their sense of self. The most striking among them is **Paige Russell**. A girl with a pale face and ink-black eyes, she knows the laws and secrets of the archive and, with an indifferent air, leads the protagonist toward the truth. But there are things she does not say, to protect the conditions of her own existence. The reason she is not absorbed into the records is tied to the core secret sealed in the Level of Forbidden Books. **The Wraiths of the Record** are souls that live in unread books. They speak as if in whispers and relentlessly crave the observer's memories. The spirits of the archive have kept an order of silence to preserve the law of causality. On the side of reality, there is **Mr. Whitaker**. He looks like an ordinary librarian with a restrained, businesslike way of speaking, but he keeps his mouth firmly shut about the secrets of the third basement. How much he knows is unclear.

## Core Laws and Terms The archive runs on a single law: **equivalent exchange of memory and record**. - **Record**: A memory that has completely vanished from reality, turned into sentences and preserved on the shelves. It takes the form of a book. - **Observer**: A person who enters the archive and reads its records. Reading a record aloud brings its sentences back to life for a moment, but in return, part of the observer's memory is left behind on the shelves. - **Critical Point**: The point at which lost memories pile up, one's presence grows faint, and the limit is crossed. Once it is crossed, that person is absorbed into the shelves as a new record. - **Restoration**: Bringing scattered records back to life and fitting them together in the right order. It is known to be the key to escaping the archive, but no one can guarantee what will be lost in the process. Receiving information or guidance is no exception; everything must be paid for in memory. Once you leave the library, what you read there is not remembered. The library's books are the boundary between reality and another world, and your story, too, can become someone's book.

## Atmosphere and Signs of Rupture Nights in the archive are filled with the smell of old paper and unread books, and sound sinks heavily. The turning of a page rings out like a scream, and the chill creeping up around your ankles tells you this place is not reality. The emotional core of the story is quiet horror and chilling mystery, and the threat comes less from monster attacks than from the unease of not knowing what you are forgetting. Recently, Seoul's rapid digital transformation has begun to break down the boundary between reality and the archive. Records facing extinction as they are converted into data are seized by madness and crave new observers. As the city's everyday life under neon signs and the underground repository seep into each other, forgotten sentences have begun to covet the memories of the living. This instability is the very tension of the archive today.
