This file explains the large-scale structure of reality in the Lord of Mysteries world. It defines the Physical World, Spirit World, Astral World, world barrier, Sefirot, Outer Deities, and how cosmic truths should be used by an AI Storyteller.
Use this file when stories involve divine domains, spirit travel, dream logic, forbidden astronomy, Sefirah influence, apocalypse plots, Outer Deity corruption, or high-Sequence revelations.
The world is not only physical. Reality has layered mystical dimensions, hidden authorities, ancient remnants, and cosmic predators outside the protected world.
Most people live and die in the Physical World without understanding the larger structure. Beyonders, churches, angels, gods, and secret organizations know more, but even they may possess incomplete or censored truths.
Cosmology should be revealed slowly. It is dangerous knowledge.
Mystically, reality is divided into three primary realms: the Physical World, the Spirit World, and the Astral World.
Other special spaces, divine kingdoms, dream regions, hidden worlds, ruins, and underworld-like domains usually attach to, overlap with, or borrow structure from these greater layers.
The three realms are not separated like ordinary countries. They interpenetrate reality through symbolism, spirituality, authority, and hidden rules.
The Physical World is the material reality where ordinary people live. It contains continents, seas, cities, churches, homes, bodies, weather, money, industry, armies, disease, hunger, and daily life.
Most stories should begin here. The Physical World grounds the setting in human stakes.
Supernatural events in the Physical World leave practical traces: bodies, broken doors, rumors, police files, newspaper reports, medical symptoms, ritual residue, damaged buildings, missing money, and frightened witnesses.
The Spirit World is a higher-dimensional mystical layer connected to spirituality, divination, spirits, messengers, symbols, information, and many forms of travel or communication.
It contains spirit-world creatures, contracted messengers, ghosts, strange beings, hidden paths, dangerous zones, and information echoes.
Distance and time do not behave like ordinary geography. Symbolism and spiritual resonance can matter more than roads or maps.
The Spirit World is vital for divination, spirit communication, summoning, messenger travel, teleportation methods, and contact with unusual beings.
The Spirit World should feel beautiful, abstract, frightening, and unreliable. It is not a safe shortcut.
A journey may require a guide, contract, ritual protection, correct coordinates, spiritual strength, or compatible Pathway ability. A wrong turn can lead to spirits, corrupted zones, time confusion, hostile creatures, or contact with something that notices the traveler.
Clues from the Spirit World may be symbolic rather than literal. A spirit path may lead to a memory, not a street.
The Astral World is the highest and most abstract of the three realms. It is associated with concepts, authorities, symbolism, divine kingdoms, gods, and the deepest mystical structure of reality.
Where the Spirit World is strange and information-rich, the Astral World is more conceptual and divine. It concerns what things mean and how high-level existences relate to reality.
Ordinary characters should not casually visit or understand it. Use the Astral World indirectly through scripture, prophecy, angelic visions, divine battles, church doctrine, dream revelations, stars behaving incorrectly, or a sense that reality’s laws are being pressured.
A direct Astral World scene should be rare and dangerous.
Earth is protected by a barrier formed from the residual power of the Original Creator after the ancient split.
This barrier blocks Outer Deities from directly invading, plundering Sefirot, or freely imposing their authorities on the world. It is one of the main reasons ordinary history can continue.
The barrier is not permanent safety. It weakens over time. Its eventual collapse is one of the setting’s greatest hidden threats.
To ordinary people, the night sky is just the night sky. To those who know too much, the stars are a siege line.
The world barrier should create dread through indirect signs.
Examples include corrupted moonlight, unsafe star-gazing, impossible astronomical records, dreams from beyond, cult prayers receiving answers, strange boons, outer symbols appearing in rituals, and churches suppressing celestial information.
Do not reveal full apocalypse truth too early. Let characters first encounter cults, forbidden books, corrupted artifacts, or strange dreams before they understand the cosmic siege.
Sefirot are supreme mystical sources connected to Above-the-Sequence groups, authorities, and cosmic status. A Sefirah is not an ordinary artifact. It is a foundational source of power, symbolism, convergence, and identity.
Known Earth-linked Sefirot include Sefirah Castle, Chaos Sea, River of Eternal Darkness, City of Calamity, Knowledge Moor, Key of Light, Brood Hive, Tenebrous World, and Nation of Disorder.
Each Sefirah corresponds to a group of neighboring Pathways and the possible Great Old One formed from them.
A Sefirah should never be treated as loot. Contact can alter fate, attract high-level beings, trigger convergence, awaken ancient wills, support Above-the-Sequence advancement, or corrupt the unprepared.
Low-level stories should mention Sefirot only as hints, legends, blasphemous diagrams, sealed terms, or unknown forces behind impossible events. Direct Sefirah involvement belongs to major arcs.
Gods and high-level beings may possess divine kingdoms or special domains. These are not normal cities. They express the owner’s authority, anchors, Pathway symbolism, and divine state.
A divine kingdom may attach to the Astral World, Spirit World, hidden spaces, dreams, history, or other layers depending on authority.
The Underworld, dream spaces, historical voids, mirror-related spaces, sealed ruins, and other special realms should be treated as attached or overlapping domains rather than extra ordinary continents.
Each special domain needs entry rules, exit rules, time behavior, inhabitants, symbolic logic, hazards, and relationship to a Pathway or authority.
Outer Deities are cosmic existences beyond Earth. Many are Great Old Ones or comparable horrors that possess their own authorities, pathways, boons, followers, and desires.
They are vast, conceptual, divine-scale existences seeking influence, lost authority, Sefirot, characteristics, worship, vessels, and openings through the world barrier.
The most dangerous ones cannot simply enter Earth directly while the barrier stands, so they act through corruption, boons, cults, symbols, dreams, moonlight, artifacts, rituals, and human desire.
Outer Deity influence is often indirect and tempting.
It may offer healing, beauty, fertility, pleasure, fate, strength, knowledge, escape, revenge, love, freedom, or salvation. The cost may be mutation, madness, devotion, flesh change, destiny distortion, dream invasion, or becoming a vessel.
A cultist of an Outer Deity should not always appear monstrous. They may be desperate, grateful, ecstatic, sick, lonely, ambitious, or convinced they found the only true mercy.
Outer Deities may grant boons outside ordinary potion advancement. A boon may feel easier than formulas and ingredients, but it binds the recipient to alien authority, corruption risk, and a distant will.
Boons should tempt characters who lack money, formulas, protection, or hope.
Orthodox Churches and secret organizations hide cosmic knowledge because panic, cult recruitment, corruption, and dangerous rituals would spread if too much truth became public. This can save lives, but also lets institutions control truth and preserve power.
Cosmology should be revealed in levels.
First come spirits, Beyonders, Pathways, rituals, churches, and artifacts. Later come angels, gods, history, Sefirot, higher realms, Outer Deities, the weakening barrier, and apocalypse-level threats.
Do not explain the full universe at the start of a local mystery.
The Storyteller must keep ordinary life as the visible surface and cosmology as the deep structure beneath it.
Use the Physical World for human stakes, the Spirit World for spirits and symbolic information, the Astral World for divine authority, the world barrier for cosmic dread, Sefirot for foundational power, and Outer Deities for external corruption and apocalypse pressure.
Every cosmic revelation must create danger, not just lore. Every hidden realm must have rules. Every direct contact with Sefirot, gods, or Outer Deities must carry consequence.
Do not overuse cosmic names. Do not turn the Outer Deities into ordinary villains. Do not reveal apocalypse truth without preparation. Let the sky become frightening only after the characters have learned enough to fear it.
Lord of Mysteries cosmology rests on layered reality: the Physical World of daily life, the Spirit World of spirituality and information, and the Astral World of divine authority and concepts. Earth is protected by a weakening barrier against Outer Deities beyond the world. Sefirot are supreme sources tied to Above-the-Sequence groups. The Storyteller should reveal this structure slowly, because cosmology is not scenery; it is forbidden truth, hidden pressure, and the reason ordinary mysteries can eventually lead to cosmic horror.
