Overview
The Nightmare Beast (Commonspeak), also Dagon (Elfspeak \ˈdeɪgɔn\ for monster), and Ulg'thraxa (Farspeak \ˌulgkˈθræksə\ for no known translation), is an Eldritch God associated with the Strange Realm of The Horizon, specifically the region known as The Blue Palace, and is recognized as the patron and progenitor of the Slaver Fish. Its Commonspeak name comes from its purely physical horror.
Integral scholarship classifies the Nightmare Beast as a godlike phenomenon rather than a true god. It does not display consistent intentional agency, instead, seeming as a persistent source of Strange influence, around which madness, mutation, and auditory hallucination reliably manifest. Most reliable information regarding the Nightmare Beast derives from Horizon expedition logs, Slaver Fish cult testimony, and post-incident analyses of coastal and subterranean contamination events.
History
Shattered Age
The Nightmare Beast came into existence at the very beginning of the Shattered Age, contemporaneous with the collapse of The Orrery and the transformation of the Servitors of Destiny into Eldritch entities. Prior to this event, the being now known as the Nightmare Beast is believed to have been one of the greater Fates, though no reliable record preserves its original designation or function within The Apparatus.
The formation of the Blue Palace is believed to date to this period, coinciding with the earliest recorded emergence of Slaver Fish entities.
Subsequent historical eras contain no evidence of deliberate campaigns or escalatory action by the Nightmare Beast. Instead, its presence is inferred through recurring patterns of coastal mutation, deep-lake anomalies, and cultic behavior centered on sound, echo, and enforced silence.
Description
The Nightmare Beast manifests in at least two known forms.
Anthropomorphic Form
Described inconsistently but with notable recurring features. Witnesses report a vaguely humanoid figure three meters tall, composed of slick, scaled flesh, perpetually wet as if submerged. The face presented is typically smooth and unfinished, with vestigial eyes and a mouth that does not move when speech is perceived. When this form is encountered, sound behaves anomalously: voices seem to originate from behind the listener, echoes precede their source, and spoken words linger unnaturally in the air after silence has fallen. This form is widely understood to be a cognitive mask, adopted to prevent immediate psychological collapse in observers.
Surreal Form
Vast and unmistakably inhuman, it appears as a kaiju-scale quadrupedal monstrosity with a long tail, a spined, scaled body, and multiple serpentine necks terminating in a variety of different heads. New necks and heads continuously grow from the rear of the body, while older heads detach from the front, dissolving into a viscous, translucent slurry in which the creature perpetually wades. At any given moment, between five and eleven heads are present. These heads display a wide range of forms, including animals, mortals, and anatomies that do not correspond to any known species. All share the same vacant, unblinking gaze. No head appears to act independently, nor do any show evidence of individual awareness.
Personality
The Nightmare Beast is understood to embody the Strange Epiphany of audition, granting it absolute mastery over sound, vibration, and the perception of hearing. Integral scholars caution that this does not imply a personality oriented around communication or expression. Rather, the Nightmare Beast appears to experience reality as a continuous acoustic field, in which identity, memory, and intention are patterns of resonance rather than discrete thoughts.
Like all Eldritch Gods, the Nightmare Beast does not display recognizable psychology. Its behavior is inscrutable and inconsistent, offering no evidence of intention, desire, or awareness. Integral scholars increasingly caution against assuming consciousness at all, suggesting that Soma may function as a masked phenomenon rather than an agent, analogous to a Chinese Room executing a process without understanding.
Abilities
The influence of the Nightmare Beast manifests as a progressive auditory and linguistic corruption, unfolding through distinct and increasingly catastrophic stages. Integral scholars classify this progression as a perceptual infection of audition, culminating in total loss of volitional control mediated through sound.
Environmental Cues
Regions under Dagon’s influence exhibit pronounced auditory anomalies before any visible biological mutation occurs. Echoes manifest without discernible sources. Voices appear to travel through water, stone, and solid walls. Groups of individuals may unconsciously synchronize speech, repeating identical phrases in perfect unison despite having no awareness of doing so.
Written language remains initially unaffected, though prolonged exposure often results in compulsive inscription of meaningless symbols believed to be crude attempts to record the alien whisper. Silence in such regions is reported as oppressive and unstable, frequently broken by distant murmurs that no individual claims to hear directly.
Early Corruption: Perceptual Awareness
The initial stage is marked by auditory hallucinations, typically described as whispers in an unfamiliar language. These sounds are intermittent, faint, and easily dismissed. Affected individuals often report the sensation of being overheard rather than addressed, as though sound itself has become attentive.
At this stage, ordinary hearing remains intact, and the afflicted can still understand and produce normal speech without difficulty.
Advanced Corruption: Perceptual Otherness
As corruption advances, the afflicted develops increasing difficulty processing ordinary language. This manifests as aphasia: spoken words are heard clearly but lose meaning, familiar speech feels distorted, and reading comprehension deteriorates.
Concurrently, comprehension of the alien whisper improves. The language remains impossible to consciously translate, yet its intent becomes intuitively clear. Subjects frequently report distress at realizing they understand something they cannot think about. The whisper begins to feel external, intrusive, and directive.
Terminal Corruption: Catastrophic Auditory Obedience Disorder
In the terminal stage, the afflicted loses all capacity to comprehend non-Eldritch language. The alien whisper becomes the sole intelligible mode of communication. At this point, the subject no longer merely hears commands; their body responds to sound without mediation by will.
Victims commonly beg for help while simultaneously carrying out violent or self-destructive acts dictated by the whisper. Consciousness persists throughout, leaving the original identity fully aware and fully imprisoned within flesh that no longer obeys. Integral healers classify this condition as Compulsive Auditory Obedience Disorder, universally fatal without intervention.
Orisons
Most Orisons of the Nightmare Beast originate among the Slavery Fish, for whom it functions as both god and origin myth. Slaver Fish Orisons serve as living resonators, amplifying their patron’s influence through ritual sound, subsonic vibration, and communal chanting beneath water or mucus-saturated environments.
Among mortals, the Nightmare Beast most often draws the attention of individuals with obsessive relationships to sound. These include musicians who pursue absolute tonal perfection, audiophiles in search of musical ecstasy, scholars who study acoustic phenomena. In most cases, the resulting Pact is not sought, but imposed, manifesting as an involuntary curse.
Cultic veneration of the Nightmare Beast centers on unbroken sound. Rituals emphasize continuous chanting, droning, layered vocalization, and deliberate auditory overload. Silence is treated as hostile, dangerous, or blasphemous.
Among Slaver Fish, this practice takes the form of vast, underwater choruses, where thousands of voices resonate through viscous secretions that carry sound with unnatural clarity. Mortal cultists attempt crude imitations, often resulting in permanent auditory damage or accelerated onset of aphasia.
Notable Orisons include:
- Talvescu of the Quiet Hold: Human, Man, Norhome, Dawn Age, Dead. A architect from coastal Agria who attempted to design a city in which no sound could echo. Survivors reported that the city began to whisper in familiar voices before collapsing into the sea.
- Sister Halvraine: Human, Woman, Norhome, Dark Age, Dead. A monastic cantor from whose hymns were said to induce mass hallucinations. She vanished during a ritual performance; the abbey lake remains unnaturally still, and sound does not carry across it.
- The Drowned Listener: Slaver Fish, Horizon, Shattered Age, Alive. Legends credit it with the creation of the first mind-bound fish-kin, achieved through sustained harmonic exposure rather than physical alteration.
