Lore & Background

Ozen was once a celebrated explorer who reached the highest ranks of the White Whistle guild. Her life changed irrevocably when she descended into the Abyss, eventually becoming the leader of the Seeker Camp on the second layer. Instead of succumbing or fleeing, she adapted to the hostile environment, building a sanctuary among the camp's facilities. Over decades, she accumulated vast knowledge about the ancient technology buried beneath the earth, and she is the one who discovered Reg and brought him to the surface, giving her direct knowledge of his origins and a known connection to his creator, Lyza. She understands the mechanics of the Curse better than any living surface dweller. Despite her gruff exterior and eccentric behavior, Ozen retains a deep sense of duty toward those brave enough to follow her into the darkness. Her existence proves that survival in the Abyss is possible with sufficient preparation and willpower. Ozen is unaffected by the Curse of the second layer due to her physical conditioning and training, and she does not suffer its effects.

In Their Own Story

The cavern hummed with the sound of dripping water and distant grinding stone. Ozen sat cross-legged on a pile of scrap metal, polishing his goggles with a rag stained by oil and old blood. Riko watched from the shadows, her breath held tight in her chest. The old man didn't look up as he spoke, his voice raspy like shifting gravel. You think the Abyss wants to be found? He chuckled, a dry sound that echoed off the walls. It only wants to be left alone.

Reader's Guide

Ozen serves as a reluctant mentor and guardian of secrets within the sixth layer of the Abyss. Once a renowned White Whistle explorer, he fell into the depths decades ago after losing his family to the Curse. Now living in isolation, he possesses vast knowledge about ancient artifacts and the true nature of the abyssal phenomena. His arc transforms him from a suspicious recluse into a crucial ally for Riko and Reg. He wields immense physical strength and utilizes specialized excavation tools to navigate dangerous ruins. Unlike most survivors, Ozen has developed a unique tolerance to the Curse through sheer endurance and time spent underground. This resilience allows him to operate in layers that would kill ordinary humans almost instantly. His combat style relies on heavy machinery and brute force rather than agility. Defining moments include his revelation of Reg's origins as an artificial White Whistle. He also aids Nanachi by confirming the tragedy behind their past life. Despite his gruff demeanor, Ozen cares deeply for the new generation of explorers. His ultimate sacrifice involves remaining in the depths to ensure Riko and her friends can ascend safely, cementing his legacy as a tragic hero.
