Abyss

Biodata

Nature and Structure

The Abyss is a vast demonic world composed of countless fragmented planes rather than a single plane. It is the homeland of demons, whose bodies and bloodlines cannot properly grow on Material World food alone. 14 21

• Demons are extraordinary creatures whose inherited bloodlines can contain racial knowledge, languages, codices, and runes. 19 20
• Demons possess physical bodies in the Abyss; Demon Bloodline descendants in the Material World instead rely on crystal cores. 23
• Abyssal aura can serve as a prerequisite for rituals such as the Dretch Sacrifice, which exchanges murdered victims' chaotic souls for Soul Crystals. 14
• The Abyss contains shallow planes ruled by demon lords, including the territories of war demon Romance and the Scarlet Territory Soul Crystal mine. 46

Abyssal Will and Passage

Abyssal Will

The Abyssal Will is an immense, emotionless presence associated with demon prayers, bloodlines, and Abyssal resources. During the Monkey Quasits' collective prayer, it examined their bodies and bloodlines before granting them a Bloodline Origin Crystal. 45

• The Will is described as never refusing a demon's prayer. 45
• It holds the greater share of the Monkey Quasit ancestral blood-source rune created from the Quasits' Bloodline Origin Crystal. 47
• It forbids Soul Crystals—considered strategic Abyssal resources—from being transported out through Abyssal Summoning. 48

Abyssal Sacrifice and Summoning

• Abyssal Sacrifice — The Abyss accepts sacrifices, though only genuine treasures receive corresponding recompense. Demons may return home through self-sacrifice; for other races, the offered sacrifice is genuinely consumed. 21
• Abyssal Summoning — Can call Abyssal demons through a rune and an aura-bearing medium, but a summoner without suitable terms risks being killed by the summoned demon. 20
• A refused targeted summoning may become random; even a Zero-Ring summoning can potentially contact a demon king. 49

Inhabitants and Influence

• Quasits — First-Ring demonic beasts from the Abyss. They are naturally cautious, cowardly, and specialized in hiding and fleeing rather than direct combat. 14 23
• Quasit Bloodline descendants — Parasitize humans, manipulate hosts' emotions, and drive murders to produce chaotic souls for Quasit consumption. 14 16
• Monkey Quasits — Artificial Quasits created from macaques through Yin Ming's Bloodline Potion. A total of 962 were sent into the Abyss to acquire Soul Crystals. 19 46
• Red Nose — A Monkey Quasit released into the Abyss by Yin Ming; later becomes an overseer at a Soul Crystal mine and reveals the Beck Subplane as an alternative to dangerous summoning-based trade. 21 46 49
• Demon King Christine — A demon ruler who receives reports concerning Abyssal activity in the Material World and assigns punishments to subordinates. 24 25
• Dinaya Aman — A succubus operating between the Abyss and Material World; she reports the death of the Quasit Jeroffi and the exposure of a demon altar. 24

Presence in the Material World

Quasit descendants entered the Material World to infest human hosts and harvest souls created by murder. Their hosts included stewards across Count Golden Lion's territory, where they used exploitation and killings to generate suitable souls. 14 16

• A demon altar beneath Count Golden Lion's castle served as a hidden Abyssal coordinate and passageway; numerous demons had already descended and concealed themselves in the Material World. 24
• The death of a Quasit stationed in the Material World alerted Abyssal forces to the altar's compromise and the risk of a human wizard purge. 24
• Large-scale Abyssal Sacrifices produce detectable Abyssal Will fluctuations, prompting investigation by the Wizard Black Tower. 46

Soul Crystals

Soul Crystals are Abyssal minerals consumed by demons and used by Yin Ming to enhance mental power or bargain for the release of Soulstones. 14 21

• High-quality Soul Crystals are demon food; prolonged consumption of cloudy crystals can cause degeneration, loss of control, and madness. 21
• Red Nose and other Monkey Quasits were promised the return of their Soulstones in exchange for 10,000 Soul Crystals each. 21 45
• Although Quasits can mine or earn Soul Crystals in the Abyss, the Abyssal Will's export restriction prevents them from delivering the crystals through normal summoning. 48

Beck Subplane

Beck is an Abyss-owned neutral trading subplane, approximately half the size of the Landon Duchy. It has no native inhabitants and exists solely for extraordinary beings to exchange goods. 49

• It opens on every New Moon Night. 49 50
• Demons may enter freely, while wizards, warlocks, and Magic Beasts require a Beck Subplane Invitation. 49
• Fighting, hunting, and killing are forbidden regardless of race or prior enmity. 49
• Though it belongs to the Abyss, Beck is not shrouded by the Abyssal Will. 49
• Yin Ming enters Beck using an invitation sphere after disguising both his body and magical aura. 50
