Dagon, Nightmare Beast

Overview

The Nightmare Beast (Commonspeak), also Dagon (Elfspeak \ˈdeɪgɔn\ for monster), and Ulg'thraxa Veyruul (Farspeak \ˌulgkˈθræksə ˈveɪrul\ 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.

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.

Its anthropomorphic form is described inconsistently but with notable recurring features. Witnesses report a towering, vaguely humanoid figure 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.

The surreal form of the Nightmare Beast is 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.

The Nightmare Beast’s presence is associated with severe environmental distortion. Sound travels unpredictably, water becomes thickened or gelatinous, and living creatures experience intrusive auditory hallucinations, often described as remembered voices speaking words never heard aloud.

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.

Behavior attributed to the Nightmare Beast suggests compulsive engagement with sound. It is drawn to environments of extreme silence or extreme noise, and its manifestations often follow prolonged periods of auditory deprivation, sensory overload, or ritualized chanting. The creature does not appear to distinguish between meaningful and meaningless sound; screams, prayers, and ambient noise are treated with equal apparent interest.

Attempts to infer motive from these behaviors have proven unsuccessful. The Nightmare Beast does not respond predictably to supplication, threat, or negotiation. Its actions are best understood as the external consequences of an epiphany that renders all existence audible and therefore vulnerable.

Abilities

Integral scholars identify a consistent progression of auditory corruption associated with the Nightmare Beast’s presence or attention. This progression appears to function as a form of perceptual infection, beginning subtly and escalating into total cognitive subjugation.

The earliest stage is characterized by auditory hallucination, typically reported as whispers or murmurs in an unrecognizable language. These sounds are initially sporadic and easily dismissed, often mistaken for environmental noise or stress-induced phenomena.

As exposure deepens, affected individuals develop increasing difficulty processing ordinary language. This manifests as various forms of aphasia: words are heard but not comprehended, familiar speech becomes distorted, and meaning slips away even as sounds remain clear. Paradoxically, comprehension of the alien whisper improves during this stage, producing intense confusion and distress.

In advanced cases, the subject reaches a terminal state in which only the whisper remains intelligible. All other language is reduced to meaningless noise. At this point, the afflicted no longer merely hear the Nightmare Beast; they are compelled by it. Speech becomes involuntary, consisting of repeated utterances in a language the speaker cannot consciously translate. Subjects frequently beg for help even as they carry out acts of violence or self-destruction under external auditory command.

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, scholars who study forbidden acoustic phenomena, sailors driven mad by unending waves, and prisoners subjected to prolonged isolation or enforced silence. In many cases, the resulting pact is not sought, but imposed, manifesting as an involuntary curse.

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.
