Revision 2

Overview

Encroachment is the phenomenon by which proximity to Anomalies affects ordinary humans in Hethereau. The closer a person gets to anomalies, or the more time they spend studying and interacting with them, the more likely they are to experience Encroachment. Its effects are unpredictable and can impact both the body and the mind, making it one of the most significant risks for anyone who works with or lives near supernatural phenomena.

Encroachment is not a simple binary state. It exists on a spectrum: casual, brief contact with a minor anomaly carries far less risk than prolonged, intensive study of a powerful one. For most ordinary citizens of Hethereau, day-to-day life involves enough distance from dangerous anomalies that Encroachment is not a serious concern. But for anomaly researchers, Bureau agents, and independent hunters, the risk is constant.

Effects on the Body and Mind

The specific effects of Encroachment vary from person to person and cannot be predicted in advance. Some individuals experience physical changes, while others undergo psychological shifts. The unpredictable nature of these effects is part of what makes working with anomalies so dangerous. There is no way to know ahead of time how a given person's body or mind will respond to sustained anomaly exposure.

This unpredictability also means that Encroachment is not inherently harmful. While many of its effects are disorienting or dangerous, the same process that destabilizes ordinary humans is also the mechanism through which some individuals develop extraordinary powers.

Connection to Esper Awakening

Encroachment is the bridge between ordinary humanity and the supernatural. Prolonged anomaly exposure through the Encroachment process is what causes certain humans to develop abilities and become Espers. Not everyone who experiences Encroachment awakens as an Esper; the conditions for awakening appear to depend on individual factors that are not fully understood. But for those who do awaken, Encroachment is the catalyst that transforms them from normal people into beings with supernatural powers.

The protagonist of Neverness to Everness, Esper Zero, was awakened through Encroachment prior to the events of the game. Their experience with the process gave them a rare and powerful ability: the capacity to see the true essence of anomalies and communicate with them. This ability drew the attention of the Bureau of Anomaly Control, which recruited Esper Zero to help manage the city's growing anomaly crisis.

Implications for Hethereau

Encroachment shapes life in Hethereau in subtle but pervasive ways. Ordinary citizens are aware that spending too much time near anomalies carries risks, which influences everything from real estate values to career choices. Areas with higher anomaly activity may be less desirable to live in, while professions that involve direct anomaly contact (such as Bureau agents and independent hunters) carry occupational hazards that go beyond the physical dangers of combat.

The existence of Encroachment also raises questions about the long-term future of Hethereau. As anomalies continue to appear and interact with the city's population, the number of people affected by Encroachment may grow. Whether this leads to more Esper awakenings, more unpredictable side effects, or both remains one of the open tensions in the game's lore.
