Echoes

Lore & Background

The Curse does not manifest as spectral doppelgängers or ghosts, but rather attacks the body's very fabric. As a traveler ascends from Layer 1, they begin to experience mild symptoms such as nosebleeds and headaches. From Layer 2, nausea and vomiting set in. From Layer 3, hallucinations, vertigo, and disorientation occur. From Layer 4, the curse escalates to intense pain and bleeding from all orifices, often described as feeling like their insides are being torn apart. While hallucinations may occur due to extreme pain and delirium, there is no evidence of sentient 'Echoes' mimicking loved ones; the true horror lies in the relentless physical disintegration that serves as a final barrier to escape. The deeper one descends, the more absolute this punishment becomes, ensuring that few can return alive without the aid of specialized countermeasures such as acclimatization. Artifacts like the Unheard Bell are used for communication with the dead or echoes of the past, not for protection against the Curse.

In Their Own Story

The air in the fifth layer tasted of rust and old blood. Riko stopped, her breath hitching as the silence of the cavern suddenly filled with the sound of her own voice calling out for Nanachi. She turned slowly, expecting to see her friend behind her, but there was only the jagged rock face. Then, a figure stepped from the shadows—her own face, pale and cracked like dry clay, wearing Riko's white scarf. The thing smiled, a expression too wide, too human, yet utterly devoid of warmth. 'Come home,' it whispered, not with Riko's voice, but with the grinding sound of tectonic plates shifting deep below.

Reader's Guide

Echoes are not weapons to be wielded or tools to be used; they are a natural defense mechanism of the Abyss that must be endured or avoided. They function as a psychological and spiritual trap, targeting the mind of anyone who violates the Curse by ascending from prohibited depths. To survive an encounter with Echoes, a traveler must possess absolute mental fortitude and often rely on artifacts like the White Whistle to dampen their perception of the phenomenon. Without such protection, the victim is likely to succumb to madness or be physically consumed by the spectral force. No one 'wields' Echoes in the traditional sense. They are an environmental hazard that escalates with depth. The only way to counter them is through the use of specific protective gear found in the lower layers or by accepting the fate of remaining below, as ascending triggers their manifestation.

Did You Know?

• The Curse begins to take effect immediately upon ascending from Layer 1, with mild symptoms like nosebleeds and headaches; from Layer 2, nausea and vomiting; from Layer 3, hallucinations, vertigo, and disorientation; and
• Unlike psychological hauntings, the primary danger is physical: victims suffer nosebleeds, vomiting, convulsions, and eventual death within minutes or hours depending on depth.
• There are no confirmed instances of spectral 'Echoes' or ghostly doppelgängers; reports of such phenomena are likely hallucinations caused by extreme pain or delirium.
• Countermeasures include spending significant time in the lower layers to acclimatize. The Unheard Bell is not a protective artifact; it allows communication with the dead or echoes of the past.
