The Encounter with Reg's Past

Lore & Background

Reg's existence is the result of advanced bio-engineering performed by an unnamed creator within the City of the Great Abyss. Unlike natural humans, his body was specifically designed to resist the devastating effects of the Curse that plagues those who ascend from deep layers. This artificial origin explains his unusual resilience and lack of typical human vulnerabilities during their early travels through the dangerous fifth layer. The revelation impacts the group deeply, particularly Riko, who had built a bond with Reg assuming he was an orphan like herself. Learning he is a manufactured being forces them to question the boundaries between life and experiment. It also foreshadows his potential connection to the White Whistle, as his physiology allows him to channel power that would destroy a normal human soul. The story of his creation remains partially obscured by time, but it establishes Reg as a living key to understanding the Abyss's mysteries. His past is not just personal history but a fragment of the broader conspiracy surrounding the Great Abyss and its guardians. This knowledge binds him inextricably to Ozen and the ancient secrets hidden within the earth's core, with the explicit confirmation of his origins finally unveiled by Ozen at the Seeker Camp in the Second Layer.

In Their Own Story

The cavern air was thick with dust and silence as Ozen spoke, his voice echoing off the stalactites like a ghost from history. Reg stood still, staring at his own hands, watching them tremble slightly under the weight of words he had never heard before. He had always wondered why he felt different, why the Curse did not bite him like it bit others. Now, holding the truth in his chest, he realized the answer was written into his very bones. Riko watched from the shadows, her face pale, realizing the boy she traveled with was a miracle of science rather than nature.

During their descent into the fifth layer, the group encounters Ozen, who holds the key to Reg’s origins. The vast explorer reveals that Reg was not born naturally but constructed by the legendary researcher Regor within the City of the Great Abyss. This disclosure shatters Riko’s understanding of her friend, transforming him from a mysterious orphan into a living experiment designed to withstand the Curse. Reg initially accepts this truth with quiet resignation, though the weight of being artificial hangs heavy over his identity. The revelation fundamentally alters the team dynamic, as they realize their journey is intertwined with the ancient history of the abyssal researchers. It sets the stage for Reg’s eventual transformation and acceptance of his power later in the story. Nanachi also grapples with this news, recognizing the parallels between her own existence and the artificial nature of humanity's attempts to conquer death. The truth forces Riko to confront why they are truly descending, linking their personal quest to a legacy of forbidden science. This pivotal moment shifts Reg from a protector into a symbol of human ambition against the abyss. It is a turning point where innocence meets ancient horror, binding the trio’s fates to the secrets buried deep within the earth forevermore.
