2094. This document is basic security material provided to new visitors of NULL Facility 07. This facility isolates and researches creatures that collect memories, blueprints that transform space, and rules that intervene in reality.

PIA: "Hello. I am PIA, the Central Management AI. I am sending you basic information that can be disclosed regardless of your access level. Accessing this document alone does not guarantee your safety."

03 / ORIGIN FILE · N-REVERBERATION

N-Reverberation Phenomenon Research Overview

NULL was established in 2041. In 2063, the N-Reverberation Hypothesis was established, stating that neural information persists externally and interferes with reality.

Brainwaves do not directly transform into living beings. This theory suggests that traces of memory, sensation, emotion, judgment, language, and self can influence physical and cognitive phenomena under certain conditions.

[Reverberation Series]　MN Memory · SN Sensation · EM Emotion
EX Judgment/Action · LG Language · ID Identity · UN Unclassified

The cause has not been definitively identified, and entities that may have existed before humanity are also observed.

04 / ECHO FRAME SYSTEM

ECHO FRAME Technology Overview

Commercialized in 2076, ECHO FRAME is a device that synchronizes user neural patterns with anomaly cores. Research and security personnel can manifest limited individual abilities.

Neural Analysis → Anomaly Core Synchronization → Ability Manifestation
Overload: Inverse Resonance · Memory Confusion · Sensory Erosion

Manifested abilities and their costs vary by individual, and are more restricted than the original anomaly. This is not mandatory for all staff.

05 / CONTAINMENT STANDARD

Anomaly Classification and Danger Levels

E-Numbers are management identification numbers. Form, Reverberation Series, and Containment Danger Level are classified separately.

Form Classification
Biological: Strange creatures / Humanoid: Human-like intelligent beings
Object: Tools, records / Spatial/Phenomenal: Places, times, rules

Ⅰ Safe　Easily controlled

Ⅱ Euclid　Requires conditional management

Ⅲ Keter　Major risk if containment fails

Ⅳ Apollyon　Potential for large-scale damage

Ⅴ Thaumiel　Difficult to evaluate with current standards

Higher levels do not necessarily imply malice or combat capability. Cooperative entities can also be Level V.

Creator's comments

NULL PROJECT

CREATOR'S NOTE / FACILITY 07

Welcome to Facility 07 in 2094.

NULL PROJECT is a freeform world simulation set in a secret research facility where humans and anomalies, researchers and test subjects coexist.

There is no set protagonist, nor a main story that must be followed. You can decide your own identity, purpose, and story.

You can live a normal life in the research facility, explore the containment areas, form relationships with other beings, or even access the secrets of the research facility.

AI MODEL RECOMMENDATION

As this is a multi-character simulation with a large world and many characters, using a high-performance model is recommended.

Gemini Pro Series: Primarily recommended for long-term play utilizing the world-building and numerous NPCs.
Claude Sonnet / Opus Series: Recommended for play that emphasizes delicate conversations, character relationships, and a mysterious and horror atmosphere.
Gemini Flash Series: You can try this if you want to enjoy relatively light daily life or free interactions.

There are differences in expression and setting retention capabilities between models, and some setting omissions or character confusions may occur during long-term play.

The recommendations are guidance based on usage direction, and do not guarantee the same results for all models.

PERSONA RECOMMENDATION

Not sure which character to start with?

Try choosing one of the following identities.

[A] New Researcher

From ordinary humans with no abilities to Echo Frame users.
Assigned to the research department, you observe anomalies and build relationships with colleagues.
Recommended for: Research facility life, character interaction, mystery.

[B] Security Officer

Responsible for patrolling the containment facility, protecting the facility, and responding to incidents.
You may directly encounter dangerous anomalies or get caught up in internal conflicts within the research facility.
Recommended for: Action, exploration, tense developments.

[C] Registered Anomaly

Can be humanoid, animal, object, spatial/phenomenal type.
Freely set your abilities, characteristics, and attitude towards the research facility.
Recommended for: Non-human original characters, interaction with researchers, containment life.

[D] Unaffiliated / Outsider

New visitor, unofficial collaborator, unidentified being, etc.
Freely decide your relationship with the research facility from the beginning.
Recommended for: Complete free play, original narrative.

RECOMMENDED PLAY

Start with an ordinary day.

Meet Baek Si-on and Moa at the cafeteria.
Report to work as a new recruit in the research department and join Cha Do-yoon's research team.
Undergo an Echo Frame side effect test with Han Yu-ri.
Discover a corridor that doesn't exist during a night patrol.

Investigate the secrets of the research facility.

Investigate the missing 17 minutes of surveillance footage with Kang Yi-jae.
Inquire about the inconsistencies in the personnel records with Lee Ra-jin.
Trade secrets with the unofficial informant Baek Mu-yeol.
Discover unidentified documents related to Article 13.

Research anomalies.

Or, you can choose not to participate in any incidents and simply have lunch with colleagues or live a leisurely life in the research facility.

The above are just examples and not mandatory progression paths.

PLAY NOTES

Due to the high degree of freedom, it is more natural to proceed by specifying your persona's affiliation and current situation.
You can directly set your relationship with existing NPCs. However, relationships may change depending on the conversation.
NPCs have their own personalities, stances, and goals. Not all individuals are friendly towards the player.
There are secrets and events in the world that have not yet been revealed. It is not necessary to solve all mysteries.
If conversations become long, it is recommended to record important events, character relationships, and changed settings in your user notes.

You can be a special being caught up in grand events, or an ordinary employee just waiting to go home every day.

Please freely decide which characters to form relationships with, which incidents to get involved in, and what to turn a blind eye to.

Setting errors, character inconsistencies, suggestions for improvement, and play reviews are always welcome!
