The Horizon of Existence, often referred to as the Border of Nihility by the Intelligentsia Guild, marks the boundary between existence and nihility. This boundary does not pertain to the material realm but signifies the conceptual “end of reality.”
Despite the intangible nature of the border, some scholars argue that individuals affected by IX the Nihility and THEIR Path can actually perceive the Border of Nihility, akin to witnessing a total eclipse of a star. Conversely, others suggest that when this border rises like the darkened sun and reflects in one's eyes, it heralds the emergence of a new Self-Annihilator.
Despite this divergence, both sides agree on one aspect: The Border of Nihility solely affects its observers. In other words, once an individual has observed the Border of Nihility, they cannot stop this behavior and will irreversibly move towards the edge of the border, with no possibility of escape. Scholars intrigued by the Nihility speculate that affected Self-Annihilators and affected worlds will plunge into the Border itself, with their very existence eternally fixed to the other side of the unobservable Border, ultimately eradicated from reality.
Record Stamp: “Only Self-Annihilators can observe the Border.” “None of those who were drawn by it have ever returned.” … These conclusions remain challenging to verify or falsify, potentially fabricated by History Fictionologists.
