Background / History

Origin and nature

The Abyss was initially envisioned as a containment space for corrupted, broken numbers: a “temporary trash bin” in which life could arise as demon vessels. Its corruption instead became contagious, allowing those broken values to spread through demons and grow beyond containment. 958

It is the earliest of the five great calamities and embodies chaos, ruin, decay, and expansion. Its instinct is to spread until it consumes a world, destabilizing that world’s possibilities and ultimately causing collapse. 708 963

Unlike more immediate world-ending disasters, the Abyss has developed a degree of rationality. Its long-standing opposition with the gods restrains its outward expansion and gives its Will an incentive to preserve internal order while seeking a path to completion. 708 958

The Will of the Abyss

The Will of the Abyss is the intelligence governing the Abyss. It monitors the realm, judges contracts, oversees demon evolution, and treats demons as experimental subjects meant to help repair its incomplete essence. 5 411 431

Its ultimate purpose is to use virtual constructs and fragmented numbers to “refine the false into the true.” Rather than merely destroying the world, it seeks to complete itself, devour enough of reality, and become a world with Abyssal characteristics. 411 959

Structure and Environment

Feature	Description
Metaphysical composition	The Abyss is an aggregate of fragmented or broken numbers: a virtual construct that is simultaneously real and false. 409 431
Layers	The realm contains countless layers, each shaped by local Demon Lords and their Fictional Divinities. Events on one layer often remain unknown beyond nearby layers. 197 432 840
Styx	The Styx is the Abyss’s 000th layer and a manifestation of its power. It nurtures demon eggs and worms, strips powerful beings of numerical energy, and can erode even a god’s Mythical Breed essence. 414 409 932
Ten-Thousand-Abyss Plains	The uppermost layer and largest demon breeding ground, where the Styx runs openly and continuously deposits eggs for hatching. 418
Planar passages	Located on the outer layer of the Astral Realm and bordering the Ether layer, the Abyss possesses established summoning and teleportation passages to Material Planes. 425
World possibilities	Its connection to different world possibilities makes it “bottomless”; sufficiently broken demons may cross into other possibilities through deep regions of the Abyss. 840

Abilities & Systems

Contract Adjudication

The Will of the Abyss protects agreements through subjective, intelligent judgment rather than purely literal wording. Even vaguely defined breaches can invoke Abyssal punishment, while clearly specified conditions define exactly when protection ends. 5

• Contracts can bind demons and other beings through penalties for violation. 5 10
• The Abyssal contract system is central to Naimus’s later relationship with the Abyss and its Demon Princes. 307 967
• A contract can be revised when both Naimus and the Abyss accept a new shared objective. 967

Demon Evolution

The Abyss provides demons with advancement through slaughter, accumulated flesh and souls, and the extraction of “number” from those resources. 61 307

• Lesser Demons receive demonic inheritance when advancing, including knowledge and truths related to the world. 19
• Formal Demon advancement requires the Will’s intervention to extract number from accumulated resources; the Abyss takes most of the yield while the demon retains a portion. 61
• High Demons formally enter the Abyss’s experimental sequence, while weaker demons serve as reserve bodies. 411
• Demon Lords and Demon Princes advance through increasingly vast acts of destruction, potentially including the collapse of entire planes. 307

Styx Manipulation

The Styx functions as the Abyss’s greatest deterrent against gods and powerful lifeforms. 932

• It “shaves away” numerical energy from powerful beings while comparatively sparing weak newborn lifeforms. 932
• It recycles fallen demons’ broken values into eggs, worms, and new demons. 932
• During Naimus’s confrontation with the Storm God, Goddess of Precepts, and Sun God, the Abyss projected the Styx into the Astral Realm as part of a full-scale invasion. 932
• The Abyss can rapidly nourish Styx-born demons into High Demons under battlefield conditions. 932

Planar Access and Summoning

The Abyss’s passage network enables summoning, travel, and invasion across Material Planes. 425

• Sacrifices can summon demons from the Abyss to any Material Plane connected through its passages. 425
• With adjustments, non-demons and visitors from other worlds can also use the passages for interplanar travel. 425
• The Will’s surveillance can be evaded through methods exploiting the Abyss’s incomplete, half-virtual nature, such as the Arc Body Method. 431 432
• As Demon Prince, Naimus can use Abyssal fragmentation to cross crystal-wall subsystems and observe other world possibilities. 822

Power of the Abyss

The Abyss can invest power in valuable individuals and use them as proxies for its wider influence. 307 411

• It sent power into Naimus’s soul during the Battle of the Abyss in exchange for his cooperation. 307
• It tacitly allowed Naimus to retain leaked Divine Rank as an investment in his development. 411
• Naimus, as Demon Prince, can rightfully draw upon the power of the entire Abyss. 932
• Its support can reduce the pressure of major advancement, though that support may also interfere with the recipient’s independent development. 821

Limitations

• The Abyss is not a god and does not inherently possess Divine Rank. 708
• Its incomplete nature drives its need to create virtual systems, cultivate demons, and seek external resources. 411 958
• Without opposition from the gods, its expansion would destabilize its own internal order and reduce it to uncontrolled chaos. 708
• Powerful demons are heavily bound to the Abyss; leaving it at full strength remains difficult even for Demon Lords. 642
• The Will is intelligent but self-interested. It may conceal information or resist any attempt to impose deeper control over it. 936 958

Relationships

• Naimus — The Abyss’s fifth-generation Demon Prince and a major investment target. It contracted with him, supported his growth, and allows him to wield its power, though both parties remain wary of the other’s long-term aims. 307 411 840 958
• Demon Princes — Successive rulers granted immense administrative authority over the Abyss. The Will continues supporting previous Demon Princes even after a new generation takes the leading role. 840
• Demons — The Abyss’s inhabitants, resources, and experimental subjects. Their slaughter, evolution, and reincarnation through the Styx contribute to its self-completion project. 307 411 932
• Gods — Its principal counterforce. The gods’ suppression restrains the Abyss’s expansion, while the Abyss’s continued existence threatens world possibilities and divine power. 708 932
• Church of Precepts — A long-standing enemy of the Abyss. Their conflict predates Naimus’s activities, including a previous invasion of the Abyss by the God of Precepts. 357
• Balthazar — A Sin Soul whose summoning, fusion with a Berserker Demon, and return to the Material Plane were understood by Naimus as part of the Abyss’s calculations and calamity research. 357 359
• Kru — Alongside Naimus, served as a key medium through which the Abyss extended control over the other calamities. 963
• Obox-ob — The first Demon Prince. After Naimus defeated him, the Abyss signed a revised contract with Naimus rather than supporting Obox-ob’s attempt to force a separate agreement. 840 967

Story Role / Major Arcs

• Early contract system — The Abyss’s Will is established as the authority protecting demonic contracts and punishing violations. 5
• Balthazar’s origin — Naimus realizes that Balthazar’s Sin Soul and return to the Material Plane were likely arranged by the Abyss as part of its research into calamities. 357 359
• Naimus’s return — After separating from Jian Nai’s body, Naimus answers the Abyss’s summons and returns to its territory. 398
• Recognition of Naimus — Naimus enters the Styx and displays his Variant soul, divinity, and Sin Souls to gain greater recognition and autonomy from the Will. 411
• Demon Prince succession — Naimus becomes the fifth-generation Demon Prince, receiving administrative authority and the ability to perceive the Abyss as a whole. 840
• Astral Realm invasion — Naimus invokes the Abyss’s full power against the Storm God, Goddess of Precepts, and Sun God; the Styx and demon forces enter the Astral Realm. 932
• World-system agreement — Following Obox-ob’s death, the Abyss accepts Naimus’s revised contract to pursue evolution into a world system rather than remain solely a catastrophe. 967
