11Overview22Anomalies in Neverness to Everness are ranked on a numbered class scale that the Bureau of Anomaly Control uses to gauge how dangerous a phenomenon is and how much manpower its containment will require. Two classes are explicitly confirmed in official materials: Class V and Class VII. The full scale is implied to extend lower for routine disturbances, though those tiers are not named in launch coverage.44The classification system is closely held by the Bureau. Casual residents of Hethereau rarely hear the exact class of an incident until after it has been resolved, and higher numbers are treated almost as state secrets. This page summarises the confirmed tiers and what they imply for response.88Confirmed Classes1010ClassSeverityResponseKnown ExamplesClass VHigh-severity; capable of widespread destructionCoordinated multi-Esper team response, dispatched through Emergency Task DivisionsThe Wrath GR / Cloud Crisis (Nanally participated)Class VIIFatal to the casual observer; the highest confirmed classificationSpecialized containment; potentially extinction-level if uncontainedHypervortex (nearly destroyed New Helios)1212Class V1313Class V anomalies are high-severity phenomena capable of widespread destruction. Handling one requires a coordinated multi-Esper team response, usually dispatched through one of the Bureau's Emergency Task Divisions. A single anomaly hunter, even an experienced one, cannot reliably contain a Class V threat alone.1515The most prominent Class V incident in launch materials is The Wrath GR, contained during the Cloud Crisis operation. Nanally Coluccis is officially credited as a participant in that response, demonstrating the kind of high-tier Esper teams the Bureau dispatches against Class V threats.1717Class VII1919Class VII is described as fatal to the casual observer and is the highest confirmed classification in launch materials. The defining example is the Hypervortex, a Class VII anomaly that struck New Helios at dusk and nearly destroyed the city. The Hypervortex's official description includes:2121Catastrophic visual presence in the skyCapacity to draw bizarre lifeforms to EarthCapacity to transform the local environmentA unique corruption mechanism: looking directly at it infects the observer with a form of corruptionAssociated mysterious rain that turns people into violent husks of themselves2323The fatal-observer property is what distinguishes Class VII from lower classes. Most anomalies can be observed, studied, and engaged through standard hunter procedures. A Class VII threat damages anyone who perceives it directly, fundamentally changing what investigation and containment mean. Public warnings during the Hypervortex event reportedly used the phrase "Remember, do NOT look at it."2525Hypervortex Paradox2727The Hypervortex holds a paradoxical nature: it should have been unstoppable, yet is impossibly fragile. If you peer into its core, it collapses within minutes. This contradiction is part of what makes Class VII anomalies so difficult to study and contain. The protagonist, Esper Zero, possesses a unique ability to perceive anomaly cores called Nexus Sense that may be specifically suited to engaging Class VII threats.2929Implied Lower Classes3131The numbered scale implies that Classes I through IV exist for routine disturbances that a single anomaly hunter or a small team can handle. These tiers cover the typical anomaly commissions that Eibon Antique Shop and other branches accept from the public. The Bureau's official materials have not named these lower tiers in launch coverage, possibly because they are considered too routine to warrant public attention.3333Most of the anomaly bosses encountered during normal gameplay are likely Class III or IV: significant enough to require an Esper response but not at the multi-team level a Class V demands. As the lore expands through patches and story content, the lower tiers may receive their own definitions.3535Why Classification Matters3737Resource allocation: higher classes pull from broader Bureau resources, including multiple Emergency Task Divisions.Public communication: classification informs civilian evacuations and public messaging during incidents.Hunter selection: only top-tier Espers are deployed against Class V or higher threats.Aftermath documentation: classification shapes the Bureau's case file structure and the lessons applied to future containment.3939The Wertheimer Index4141Alongside the numbered classification, the Bureau uses a metric called the Wertheimer Index to measure anomaly intensity. The Wertheimer Index provides a continuous measurement scale for individual anomaly readings, while the class system provides discrete severity tiers for institutional response. The two work together: an anomaly's Wertheimer Index reading helps determine which class it should be assigned.4343Related Pages4545AnomaliesBureau of Anomaly ControlEmergency Task Division 4Wertheimer IndexHypervortexThe Wrath GRCloud CrisisNullification
