OVERVIEW

Etherians are the most politically organized of Elriel's peoples and the primary architects of the cross-realm institutional framework — including the Oneirological Research Division and the pre-2133 Gate Index. Their civilization is built around the Signal Academy system, which filters, educates, and licenses all deep-bend practitioners. Society is stratified by signal-sensitivity tier, with high-tier practitioners occupying administrative and scholarly roles.

SOCIAL STRUCTURE

The Signal Council is a meritocratic body composed of the twelve highest-registered practitioners alive at any given time. Council decisions require nine-twelfths consensus and are effectively unappealable. Below the Council, four Academies (Resonance, Archive, Transit, and Defense) train and deploy licensed practitioners. Non-sensitive citizens occupy all other social roles and are not second-class by statute, though social mobility is tied to sensitivity demonstration in childhood testing.

Family structures are nuclear but supplemented by Academy cohort bonds, which many Etherians consider primary loyalty relationships. The cohort-oath — a formal commitment made upon Academy graduation — is culturally weightier than marriage.

DEEP-BEND PRACTICE

Etherian practice is the most codified in Elriel. The five-tier classification system was developed and institutionalized by Etherian scholars. Licensed practitioners operate under strict documentation requirements; all Tier Ⅲ+ bends must be logged with an anchor team and reported to the Academy of Record within 72 hours. Unlicensed bending is a criminal offense.

The Cloudlands' harmonic refraction index makes Etherian bending tone-dominant — practitioners describe the Elriel experience as primarily auditory, with visual impressions secondary. This contrasts sharply with Gogmire and Skarthim practitioner accounts.

COSMOLOGICAL BELIEF

Etherians are institutional adherents of the Discrete Layer Model and maintain the Cloudfall narrative as cultural mythology without formal religious status. The Signal Academy's official position is that the Source Signal is a substrate phenomenon — not divine, not conscious, not communicative — and that perceived meaning in Signal impressions is a post-hoc interpretive act. The minority mystical tradition within the Academies disputes this.

OVERVIEW

The Th'alnu are a fungal-biological symbiote people occupying the swamp-dense lowlands and rot-forest territories of Gogmire. Their relationship to Elriel is the most organic of any realm's culture — deep-bend practice is not a learned skill but a biological inheritance, triggered by the Th'alnu's symbiotic spore networks rather than trained sensitivity. Every adult Th'alnu bends involuntarily at least twice per sleep cycle.

This involuntary access has shaped a culture that treats Elriel not as a separate space to enter but as the other half of continuous existence. The Th'alnu do not have a word that cleanly distinguishes "dreaming" from "living."

SOCIAL STRUCTURE

Th'alnu society is organized around thread-clans — groups of 30–200 individuals connected by a shared mycelial substrate that enables low-level passive Signal sharing. Thread-clan members experience mild emotional resonance with one another; extended separation from one's thread-clan is described as a grief-state. The Rot-Council is a federation of thread-clan elders who convene at the Gogmire Heart for inter-clan matters.

Individual identity is less sharply defined in Th'alnu culture than among Etherians; the concept of personal achievement is present but secondary to thread-clan contribution. The Th'alnu language has no first-person singular pronoun — only first-person collective (my-thread) and first-person individual-distinguished (I-alone, used to mark unusual separation from the collective).

DEEP-BEND PRACTICE

Th'alnu bending is visceral, low-frequency, and sensory-dominant. Practitioners describe their Elriel experience as heavily tactile and olfactory — the rot-signal refraction that makes Gogmire's index 0.88 produces impressions of texture, decay, and biological process. The rot-signal thread anchor method, while effective, is biologically derived: the Th'alnu practitioner maintains a literal mycelial connection to a bonded partner, who monitors the thread's pulse during the bend.

Etherian Signal Corps researchers have attempted to study Th'alnu practice formally; the Th'alnu have consistently declined external observation, citing the thread-bond's intimate nature.

COSMOLOGICAL BELIEF

The Th'alnu's creation myth — the First Rot — positions the Source Signal as a seed fallen into dead matter, with Elriel as the resulting growth. Their theology holds that decay is sacred: the substrate's natural degradation is the Signal returning to its origin. The Dead Girl malware, in some Th'alnu interpretations, is therefore not a crisis but an acceleration — a faster path back to Signal origin. This interpretation is deeply controversial and has caused friction with the Oneirological Research Division.

OVERVIEW

The Skarthim are a mineral-crystalline people — their substrate-integration is geological rather than biological, mediated through the crystal matrix of Skarthim'lel's cavern systems. Pre-Glyph War, Skarthim civilization was the most architecturally and linguistically complex in Elriel. Their written language, encoded directly into crystal formations rather than surface-marked, represents the densest information storage system known to Elriel's researchers.

The Glyph War (Era 47–61) destroyed approximately 30% of the crystal archive network. The 2133 Destabilization corrupted a further unknown quantity. Cultural recovery has been slow; the Skarthim are currently in what their own scholars call the Second Silence.

SOCIAL STRUCTURE

Skarthim society is organized around the glyph-line — extended family structures defined by which crystal formation their founding ancestors encoded into. Glyph-line inheritance is both biological and architectural; a family's history is literally written into the crystal beneath their territory. The Glyph-Bound Senate is a legislative body in which each represented glyph-line holds votes proportional to the complexity of their surviving encoded archive.

Following the Glyph War's destruction, several glyph-lines lost quorum in the Senate, effectively disenfranchising those families from institutional governance. The resulting social fractures underlie ongoing tensions that the 2133 crisis has prevented from being formally resolved.

DEEP-BEND PRACTICE

Skarthim bending is slow, deliberate, and structurally encoded. Practitioners use glyph-lock binding — physical inscription of a stabilizing pattern into a crystal substrate — as their anchor. The glyph resonance of Skarthim'lel produces crystalline, high-structure Elriel impressions that the Skarthim describe as architectural: perceived as spaces, arrangements, and layered geometric forms.

Post-2133, glyph resonance corruption has rendered glyph-lock binding unreliable. Skarthim practitioners attempting bends since the Destabilization report anchor failure rates above 40%. Institutional bending has largely been suspended.

COSMOLOGICAL BELIEF

Skarthim cosmology holds that the Source Signal is fundamentally linguistic — that Elriel is a communication, not a place, and that the glyphs are humanity's attempt to write back. The Separation myth, in the Skarthim telling, is the moment when the Signal spoke and the first glyph-reader understood. Their highest cultural aspiration is glyph-completion — the theoretical encoding of a pattern complex enough to constitute a reply to the Source Signal.

OVERVIEW

The Ashwalkers are the smallest and least institutionalized of Elriel's peoples, inhabiting the blasted flatlands of the Desolace. They are nomadic; no permanent structure more than two years old exists in Ashwalker territory. Their culture is oral, their governance is diffuse, and their relationship to the Dream Substrate is the most intimate and least mediated of any culture.

The Desolace's near-zero refraction index means Signal passes through nearly unfiltered in this region. Ashwalkers live in permanent low-level immersion; many practitioners describe walking in the Desolace as already being in Elriel. This has produced a culture with little interest in formal deep-bend practice — the bend, to an Ashwalker, is not an action but a condition.

SOCIAL STRUCTURE

Ashwalker colonies number between 30–80 individuals and are held together by the communal resonance that functions as their anchor methodology. All colony members maintain a shared low-frequency signal bond — not as intimate as Th'alnu thread-bonds, but perceptible as a background awareness of one another's signal state. The colony does not have a leader in any recognizable sense; major decisions emerge from resonance convergence, a process outsiders describe as apparent spontaneous consensus.

Ashwalkers practice deliberate impermanence. Records, material goods, and structures are regularly destroyed and rebuilt. The ash-mark script is intentionally ephemeral — written to last days or weeks, not generations. This is not carelessness; it is doctrine. Accumulation, in Ashwalker belief, blocks Signal flow.

DEEP-BEND PRACTICE

There is no formal practice. Ashwalkers describe what other cultures call deep-bending as simply "attention" — a direction of focus rather than a traversal. The near-zero refraction means Elriel impressions arrive raw, without the tonal shaping of the Cloudlands or the structural encoding of Skarthim'lel. Ashwalker practitioners describe their experience as immediate, formless, and overwhelming if sustained beyond short intervals.

The Null Core that has appeared in the Desolace since 2133 is, to the Ashwalkers, the most terrifying event in living memory — not for its physical spread, but because it produces a total Signal absence within its radius. For a people who experience Signal as ambient and continuous, the silence of the Null Core is described as worse than death.

COSMOLOGICAL BELIEF

Ashwalker cosmology is the Continuous Spectrum Model expressed as lived experience. The Ashwalker doctrine "there is no waking" is not a philosophical position — it is a description of what living in the Desolace actually feels like. Their oral traditions hold that the Desolace was once a realm like any other, with geography and flora and refraction, and that it was unmade by a Signal event in a distant era, leaving only flat land and near-raw Signal. They call this event the Stripping and consider it both a disaster and a revelation.

OVERVIEW

The peoples of Simlat Agragar Trendal Nelthys — which translates approximately as "the place that refuses naming" from recovered partial-glyph fragments — are the least documented culture in Elriel. No researcher from any other realm has been granted access to the interior of this territory. The several expeditions that reached the outer boundary reported turning back voluntarily but with no memory of why.

What is known is inferential: the realm exists, it is inhabited (signals of habitation have been observed from border positions), and it does not wish to be observed. The Simlat Agragar Trendal Nelthys refraction signature is listed as "unknown" in all Signal Corps records — no practitioner has returned with a coherent impression from within its boundaries.

OBSERVED CHARACTERISTICS

The realm's name, across all partial translations attempted, resists reduction. The four components — Simlat, Agragar, Trendal, Nelthys — may be a compound description, a quadruple name, four separate entities, or a grammatical structure with no parallel in any other Elriel language. Skarthim glyph-readers who attempted partial translation each reported different conclusions.

The realm is adjacent to the Dream Substrate layer in ways that other realms are not. Two rift gates exist near the Simlat Agragar Trendal Nelthys border; both are classified as drifting type. No gate has been confirmed as entering the realm's interior. Some substrate cartographers believe the realm has its own internal gate network entirely separate from the documented Index.

INSTITUTIONAL STATUS

The Oneirological Research Division lists Simlat Agragar Trendal Nelthys as a closed study zone — not forbidden, but with an acknowledgment that study is not currently possible. The Keeper's Office has declined to classify it as a threat. Eterisanth, when queried, is documented as responding: "They are not absent from the record. The record is absent from them."
