Zenless Zone Zero Hollows Explained: Your Essential Guide to Navigating New Eridu's Deadliest Dimensions

Updated 2026-06-18

Unveiling the Mysteries of Zenless Zone Zero's Hollows

Step into the post-apocalyptic urban landscape of New Eridu, and one phenomenon dominates all aspects of life: the Zenless Zone Zero Hollows. These aren't just anomalies; they are the very fabric of existence, bringing both immense danger and the critical resources needed for survival. Understanding the nature of these dark, disordered dimensions is paramount for any aspiring Proxy or explorer looking to navigate the treacherous world of Zenless Zone Zero.

From sudden appearances that swallow entire city blocks to the insidious Ether corruption that transforms living beings, the Hollows are a constant threat. Yet, within their chaotic depths lie valuable Ether resources, driving an entire economy and fueling New Eridu's resilience. This guide will walk you through everything you need to know about Zenless Zone Zero Hollows, from their terrifying characteristics to their profound impact on society and the types you'll encounter.

What Exactly Are Hollows?

Hollows are supernatural disasters characterized by their black, spherical appearance and unpredictable emergence. They materialize spontaneously, engulfing everything in their path and transforming ordinary environments into warped, dangerous mazes. These dimensions are not merely empty spaces; they are saturated with Ether, a potent yet deadly substance that fuels their existence and corrupts anything it touches.

The emergence of a Hollow is often preceded by unsettling signs: sudden vibrations, electrical disruptions, and objects inexplicably shifting or disappearing. Once formed, their interiors defy conventional physics, creating a constantly shifting, non-Euclidean landscape where paths can lead to unexpected destinations or even other Hollows.

The Ever-Present Threat of Ether Corruption

Perhaps the most insidious danger within Hollows is Ether corruption. Both living and non-living entities are subject to its gradual, destructive effects. The deeper one ventures into a Hollow, the higher the concentration of Etheric energy, and thus, the faster the corruption takes hold.

Effects of Ether Corruption:

Target TypeInitial SymptomsAdvanced StagesMitigation/Resistance
HumansRapid mutations, dark crystal growth, painLoss of sanity, formation of Ether "core"Anti-corruption serum, specialized gear (armor)
MachinesMalfunctions, warpingComplete degradation, Ethereal transformationHigher natural resistance than organics, Plating Agents
ObjectsDegradation, warping, weakeningFormation of large black Ether crystalsAnti-corruption serum (for small items), Plating Agents

Humans who remain exposed to high levels of Ether for too long will eventually transform into Ethereals – the monstrous inhabitants of the Hollows. While mild cases can be reversed through treatment, there is no known cure for advanced Ether corruption. Individuals with higher "Ether aptitude" possess a natural resistance, allowing them to withstand corruption for longer periods unprotected. However, even they rely on specialized gear and serums for extended exploration.

Ethereals: The Monsters Within

Hollows are not uninhabited. They are the breeding ground for Ether-based monsters known as Ethereals. These creatures are a direct byproduct of the intense Etheric energy within the dimensions. While Ethereals typically do not leave their Hollows, they pose a significant threat to anyone brave (or foolish) enough to enter. These mutant beasts attack all foreign living creatures, making exploration a constant battle for survival.

The dynamic and unpredictable nature of Hollows makes conventional mapping impossible. A path taken one day may be a dead end the next, or even lead to an entirely different Hollow. This constant environmental flux presents a unique challenge for explorers seeking to extract resources or conduct research.

To overcome these challenges, specialized tools and techniques have been developed:

  • Bangboo & Carrot Programs: These small robots, equipped with "Carrot programs," are indispensable for navigation. They predict the behavior of space within a Hollow using historical data, guiding explorers along safer routes, minimizing exposure time, and helping to avoid Ethereals.
  • Fairy System: A more advanced solution, Fairy leverages the collective computing power of nearly 80% of New Eridu's smart devices. This allows for real-time analysis and mapping of Hollows without relying on past observation data, providing an immediate understanding of the ever-changing environment.
  • Proxies: These skilled individuals act as guides, leading expeditions into the Hollows. They are often adept at navigating these dangerous zones and, in many cases, operate outside the law to facilitate exploration.
  • Anti-Corruption Gear: Essential for survival, this includes specialized armor, suits, and serums designed to mitigate the effects of Ether corruption. Organizations like New Eridu Public Security, the Hollow Investigative Association, and even bandits utilize such equipment.

Communication within a Hollow is severely hampered, making coordination extremely difficult. Only the legendary Proxy Phaethon, with their "Hollow Deep Dive System," is known to possess reliable means of external communication from within these chaotic dimensions.

The Social and Economic Impact of Hollows on New Eridu

The spontaneous appearance of Hollows devastated most civilizations, but New Eridu stands as a beacon of resilience. The city's survival hinges on a groundbreaking, albeit risky, adaptation: harnessing Ether as an energy source. This ingenious solution allowed New Eridu to not only endure the apocalypse but to thrive, industrializing and monetizing the very phenomena that destroyed the rest of the world.

Ether: The Lifeblood of New Eridu

Ether is the primary energy source for New Eridu. Advanced pipe networks extract Etheric matter directly from Hollows, converting it into electricity that powers buildings, vehicles, and appliances across the city. This reliance on Ether, however, comes with its own set of environmental consequences.

Ether Processing in New Eridu:

Process StepDescriptionOutcome
ExtractionAdvanced pipe networks draw Etheric matter directly from active Hollows.Raw Etheric energy is collected.
ConversionAbsorbed Etheric energy is transformed into usable electricity.Powers New Eridu's infrastructure and technology.
Purification (Shiyu)Leftover Ether corruption is released into the air via specialized pillars.Air purification, but also attracts and necessitates purging of monsters.

The "Shiyu" process, while purifying the city's air of excess corruption, also creates a recurring problem: monsters drawn to these pillars must be regularly purged. This constant cycle of extraction, conversion, and purification underscores the precarious balance New Eridu maintains with the Hollows.

The economic implications are vast, leading to tensions between monopolistic enterprises, various gangs, conspirators, and fanatics all vying for control or profit from the Ether trade. Outside the highly industrialized city, in rural areas and among biker gangs, traditional diesel fuel remains in use, highlighting the stark contrast in technological and energy dependence.

Types of Zenless Zone Zero Hollows

While all Hollows share core characteristics, they vary significantly in scale, activity, and impact. Understanding these classifications is crucial for both survival and strategic planning within New Eridu.

Hollow Zero

This is the ultimate progenitor, the original Hollow that consumed the old city of Eridu. While the survivors rebuilt New Eridu, Hollow Zero represents the catastrophic origin of the current world. Its immense size and activity are unmatched by any other known Hollow.

The Six Great Hollows

These are major, active Hollows that are under intensive monitoring due to their significant size and persistent activity. Though not as vast as Hollow Zero, they are massive and impossible to eliminate. Each presents unique challenges and opportunities.

Known Six Great Hollows:

Cretan HollowBallet Twins Hollow, Dead End Hollow, Fourteenth Street HollowActive
Hawara Hollow(No listed companions)Active
Lemnian Hollow(Details not provided)Active
Papago Hollow(Details not provided)Active
Pursenas Hollow(Details not provided)Active
Solove Hollow(Details not provided)Active

Community reports and player experience suggest that exploration within the Great Hollows often yields high-value resources, but comes with increased risks due to higher Ether concentrations and more powerful Ethereals.

Companion Hollows

Smaller Hollows, known as Companion Hollows, can form around larger, more active Hollows once an "Ether activity threshold" called the "Zenless Limit" is reached. These secondary Hollows are often directly linked to their parent Hollows and can offer different environmental challenges and resource opportunities.

Known Companion Hollows:

The destruction of Argos Hollow and Hollow C41 indicates that while persistent, these anomalies are not entirely invincible, though the circumstances of their destruction are not widely known.

Strategies for Surviving Zenless Zone Zero Hollows

Surviving and profiting from the Zenless Zone Zero Hollows requires more than just brute force; it demands careful planning, adaptability, and an understanding of the environment. Here are some actionable tips for navigating these dangerous dimensions:

  • Prioritize Anti-Corruption Gear: Never enter a Hollow without adequate anti-corruption serum and specialized protective equipment. Your survival depends on mitigating Ether's corrosive effects.
  • Utilize Bangboo or Fairy Systems: Rely on these intelligent companions for navigation. Their ability to map and predict environmental shifts is invaluable for finding safe routes and avoiding dead ends.
  • Understand Ether Aptitude: If you have a lower Ether aptitude, be extra cautious. Your exposure time without severe corruption is significantly shorter. Consider forming teams with high-aptitude individuals or investing heavily in protective measures.
  • Stay Alert for Ethereals: These monsters are the primary combat threat. Learn their patterns, weaknesses, and always be prepared for an encounter. Avoid unnecessary engagements, especially deeper within a Hollow.
  • Monitor Environmental Changes: Be aware of sudden vibrations, electrical malfunctions, or displacement of objects – these are all signs of an active or shifting Hollow environment.
  • Team Composition is Key: When exploring with a squad, ensure a balanced team with individuals skilled in combat, navigation, and corruption resistance.
  • Resource Management: Ether is valuable, but don't overextend your stay in pursuit of it. Know when to extract to avoid critical corruption levels.
