Not all arrivals destabilize reality.
Some persist so completely, so coherently, that the world does not reject them. These beings are not corrections, summons, or divine instruments. They are compatibility proofs—entities whose internal logic aligns closely enough with Atherfall’s permissive continuity that reality ceases to resist them.
Such entities are classified as Accepted System Anomalies.
They are rare.
They are dangerous.
They are allowed.
A System Anomaly is a being whose originating framework—skills, magic, cognition, authority—should not function under local rules, yet does so without destabilizing the world.
An Accepted System Anomaly meets three criteria:
Internal Consistency
Their power obeys its own rules without demanding the world rewrite itself.
Adaptive Negotiation
Their abilities translate into behaviors, pressures, or evolutions rather than absolute overrides.
Containment by Choice
They do not expand uncontrollably. Restraint is deliberate, not enforced.
Atherfall does not reward these traits.
It merely refrains from correcting them.
Classification: Adaptive Sovereign Anomaly
Primary Location: Kiojafell
Rimuru Tempest represents a paradox Atherfall accommodates with unusual ease: a being whose growth system is flexible rather than declarative.
His cognitive and evolutionary structures do not issue commands to reality. Instead, they interpret pressure. Skills manifest as learned responses, not permissions. Evolution remains conditional. Failure remains possible.
This places Rimuru in alignment with Atherfall’s core principle: adaptation over destiny.
His presence stabilizes rather than dominates. Kiojafell recognizes him not as a ruler, but as a persistent variable—one who could reshape the region, yet chooses to reinforce its autonomy instead.
Scholars note that Rimuru does not resist the world.
He listens to it.
Classification: Dominion-Class Anomaly
Primary Location: Hell’s Gate
Ainz Ooal Gown exists as a complete, self-contained authority framework. Unlike most arrivals, his power structure arrived intact—identity, hierarchy, magic, and restraint all bound together.
What marks Ainz as accepted is not his strength, but his discipline.
He does not impose inevitability.
He calculates consequence.
His presence creates pressure, not collapse. Domains near him bend subtly, accounting for his existence without fracturing. This has led to a rare equilibrium within Hell’s Gate, where undeath, authority, and survival coexist without expansionist failure.
Ainz does not test Atherfall’s limits.
He studies them.
Neither entity is bound to prophecy, pantheon, or correction protocol. Gods observe them cautiously. Outer Realms register them as stable anomalies rather than breaches.
Importantly:
• They are not singularities
• They are not invincible
• They are not immune to consequence
Their continued existence is conditional on restraint—something both demonstrate consistently.
Atherfall does not choose champions.
It tolerates what can persist without demanding obedience.
Rimuru Tempest and Ainz Ooal Gown are not mistakes the world failed to erase. They are evidence—that some systems, no matter how alien, can coexist with reality if they accept its right to push back.
In a world that asks “What now?” rather than “Why?”,
they have already answered.
