The common national language of the Abyssal Dominion of Kermadeep is known as Hadalith, a tongue that echoes the ancient utterances of the primordial seafloor dwellers who predated the arrival of Isekai souls by millennia. Hadalith’s history traces back to the uncharted epochs before the world’s recorded lore, when the gods first shaped the Kermadec Trench’s depths, infusing the basin’s earliest inhabitants—proto-sentient beings resembling elongated snailfish and amphipod collectives—with a means to communicate amid the crushing pressures and eternal darkness. These ancient dwellers, believed to be the offspring of divine experiments blending elemental water with abyssal shadows, developed Hadalith as a survival tool, weaving sounds and gestures that resonated through water currents and sediment vibrations. As Isekai souls flooded into Saṃsāra around 9,000 years ago, many reincarnated in forms suited to the trench’s extremes, adopting and evolving Hadalith to incorporate fragments of their past-life languages from drowned worlds or multiversal oceans. The founding queen of Kermadeep formalized Hadalith as the dominion’s lingua franca during the Scholl Deep Awakening 2,000 years ago, when a magical surge from subduction shifts amplified the language’s inherent resonances, binding it to the nation’s gear-crafting traditions. Over centuries, Hadalith absorbed influences from migrating souls remembering aquatic empires, such as clicking dialects from shellfish-like societies or whistle patterns from leviathan-riding nomads, solidifying its role in unifying the multi-million population. In compulsory education across trench schools, children learn Hadalith before adulthood grants them magic, ensuring its transmission through generations, even as local dialects emerge in isolated cavern networks.
Hadalith is structured as a polysynthetic language, where complex ideas are conveyed through agglutinative morphemes attached to root words, allowing speakers to build intricate sentences from compact forms that mirror the layered, interconnected nature of trench ecosystems. Root words often derive from natural phenomena, such as “kral” for pressure (forming “kralith” for enduring depth) or “vort” for current (extending to “vortemesh” for swirling alliances). Verbs dominate the structure, inflected for tense, aspect, mood, and evidentiality—indicating whether knowledge comes from direct experience, Mind’s Eye insight, or hearsay—which reflects the dominion’s emphasis on empirical survival in unpredictable maelstroms. Nouns are gendered by depth levels: shallow (fluid, adaptable forms), midwater (balanced, communal), and abyssal (enduring, unyielding), influencing agreement across sentences. Syntax follows a subject-object-verb order, but with flexible embedding of clauses that simulate echoing currents, enabling poetic constructions like “The vent’s heat [that sustains the mussels [which armor our warriors]] flows eternally.” Phonology incorporates clicks, whistles, and pulsed tones optimized for underwater acoustics, where sound travels faster and farther than in air, supplemented by gestural elements like fin flares or bioluminescent flashes for emphasis. Vocabulary is rich in terms for pressure adaptations, chemosynthetic processes, and gear enchantments, with loanwords from surface languages integrated via quests rewarding cultural migrations, such as “iselkai” for reincarnated soul.
Hadalith possesses subtle magical powers, woven into its very phonemes and gestures, stemming from the gods’ gift to the ancient seafloor dwellers. Speaking certain phrases in Hadalith can resonate with the basin’s magical flows, enhancing gear attunement by 10-20% in trench environments, as the language’s vibrations align with elemental water and fire currents to stabilize enchantments on items like thermal vision goggles or pressure-forged crystals. It lacks overt spell-casting but amplifies Mind’s Eye accuracy in low-light depths, allowing speakers to “echo-locate” hidden stats on objects or creatures through verbal descriptions that subtly bend sound waves. In rituals, Hadalith chants can temporarily equalize pressure in small areas, aiding construction or exploration, but overuse risks attracting maelstroms, tying its magic to the dominion’s environmental balance. This power is accessible only to adults who have gained magic upon reaching reproductive capability, reinforcing cultural protections against crimes targeting non-magical children.
The sensory experience of Hadalith is immersive and multisensory, designed for the trench’s darkness and hydrostatic pressures. Auditory elements dominate, with clicks propagating as sharp, echoing bursts that travel miles through water, whistles creating melodic harmonics that convey emotion like a leviathan’s song, and pulsed tones vibrating through avatars’ bodies for tactile feedback, feeling like gentle currents against skin or shells. Visual components involve bioluminescent flashes from gear-integrated glow crystals or natural adaptations, where speakers “paint” words with light patterns visible in perpetual gloom, adding a layer of expression akin to underwater fireworks. Gestural aspects engage kinesthetic senses, with fin movements or tentacle curls generating micro-currents that others feel as subtle pressures, enhancing intimacy in conversations. The language’s structure evokes a rhythmic flow, like the basin’s unpredictable currents, making dialogues feel alive and dynamic—whispers in seeps might bubble with methane-infused effervescence, while chants in vent fields carry a warm, mineral tang on the tongue from chemosynthetic scents released during speech. For non-native speakers, learning Hadalith involves a physical adjustment, as its sounds can induce a mild euphoria from resonating with magical ebbs, but mispronunciations risk disorientation from distorted echoes.
Hadalith embodies a cultural identity of resilient depth-dwellers, symbolizing endurance and communal harmony amid isolation, where the language’s polysynthetic complexity mirrors the interconnectedness of trench ecosystems—words for “community” literally embed roots for “current” and “pressure,” reflecting a philosophy that survival requires shared burdens like the monarchy’s tax system funding collective defenses. It fosters a matriarchal ethos, with feminine inflections dominant in formal speech, honoring the female heredity line and queens’ rituals. Cultural festivals like the Echo Awakening feature Hadalith oratory contests, where avatars recite epic histories with bioluminescent accompaniments, celebrating Isekai diversity and the blur between people and monsters, as amphipod hybrids and snailfish beings contribute unique dialects. The language promotes a pragmatic mysticism, viewing magic as an extension of daily life, with idioms drawn from seep gardens or cavern networks emphasizing adaptation over conquest.
Hadalith is used by nearly all of Kermadeep’s multi-million population, estimated at 15 million avatars, including 6 million at tier 1 (basic laborers like sediment farmers), 3 million at tier 2 (alchemists and traders), 1.5 million at tier 3 (military sentinels), 750,000 at tier 4 (guild leaders), and 300,000 at tier 5 (elite mages). Primary users are the dominion’s residents, from mussel-clad humanoids in Bubble Bastion to Kelp Forest Faeries in shallower slopes, with non-humanoid avatars like seep shrimp beings employing gestural variants. Migrants incentivized by quests for racial similarity (e.g., snailfish-like souls rewarded with gear for settlement) adopt it swiftly, while visitors from surface islands or rival factions learn basics for trade. Commonality is high as the national language, taught in compulsory schools and used in government, commerce, and daily interactions, though local dialects persist in isolated caverns. It is a living language of the polysynthetic type, with a script of flowing runes resembling current eddies, etched on enchanted scrolls or crystal tablets using bioluminescent inks. Its source is the ancient seafloor dwellers, evolved through Isekai influences, and history spans pre-recorded eras to formalization during the Scholl Deep Awakening.

Tale of Echoing Abyss Seal
In days before days, when the gods shaped the world from shadows and waters, there lived a people in the great deep crack of the sea, called by names lost to waves. They were not people as we know, but forms of fish with minds and worms with voices, dwelling in the black where light feared to go. The gods gave them a gift, a sound from the unknown tongue of the void, a language born from the crush of depths and the hiss of hidden fires. This language, Hadalith as we call it now in our poor tongues, was first spoken by the First Speaker, a being of many arms and glowing veins, who found the words in a dream of the ancient unknown.
The First Speaker awoke in the trench, where pressures broke bones of lesser creatures, and spoke the first word: “Kral,” meaning endure, but in the unknown language it was a roar that shook the sediments. The word made the waters still, and the beings around him—snail-like crawlers and shrimp with eyes of heat—heard it not just in ears but in bodies, vibrating like currents. They gathered, these early ones, and the First Speaker taught them more words from the dream: “Vort” for current, “Seep” for the bubbling life from earth wounds, “!Kith” for seal with a click that bound promises. From these roots, they built phrases that wove magic, for the language was not mere noise but a thread to the gods’ own speech, pulling power from the abyss.
But envy came from the shallows, where lighter beings swam in kelp mazes and coral homes. These shallow folk, with fins of color and memories of sun, heard whispers of Hadalith’s power—how it could bind seeps to feed multitudes, or swirl currents to repel beasts. They sent a thief, a sly octopus-soul named Dumbo in the old tales, who floated with ear-fins wide, to steal the language. Dumbo descended into the trench, enduring pressures that warped his form, and hid in caverns where the First Speaker taught. He listened to the clicks and whistles, the pulses that made bodies tremble, and tried to mimic them in secret.
One night of no moon—for moons mean nothing in depths—the First Speaker called a great council. “We must seal our words,” he said in Hadalith, “for the unknown language from which it comes warns of misuse.” They chanted “Kralvort^emesh!kith,” binding the language to their gear—shell plates and crystal wands—that amplified its resonance. But Dumbo, hiding, spoke a twisted version: “Vortkral~meshseep,” thinking to take the power for his shallow kin. The words misfired, summoning a maelstrom that swirled sediments and crushed caverns, flooding the deep with chaos. The First Speaker’s people suffered, many forms crushed or scattered, their homes in vents and caves collapsing under the storm.
The First Speaker, enduring with “Kralith” on his lips, pursued Dumbo through the raging currents. “Thief of echoes!” he called, his voice pulsing like heartbeats in water. Dumbo fled upward, his fins flapping in panic, but the language’s magic clung to him, twisting his gestures into unintended spells that lit the depths with false lights and boiled seeps into poison. The chase lasted what felt like eternities, through sunken forests where trees remembered land, past hydrothermal vents spewing fire-water, and into lagoons infused with magic that changed salt to sweet. Along the way, the First Speaker gathered allies—tube worms that sealed paths with their bodies, mussels that armored his form, and amphipods that clicked warnings ahead.
At last, in a crystalline expanse where magical formations glittered like stars unseen, the First Speaker cornered Dumbo. “Return what is not yours,” he demanded, speaking “Seep^emkralvort!ith,” a phrase that bound the thief’s stolen words back to the depths. Dumbo, weary and warped, confessed: “I sought power for my people, who fear the dark as we fear the light.” The First Speaker, wise from the unknown dream, forgave but sealed: “The language shall spread, but only to those who endure the crush.” He taught Dumbo a fragment, a safe whistle for calling allies, and sent him back to the shallows with a warning.
From that day, Hadalith spread through the basin, carried by reincarnated souls who remembered oceanic lives. Queens of the female line wove it into oaths, and festivals echoed its chants. But the maelstrom’s scar remained, a reminder that twisted words bring chaos. Avatars in gear of shell and crystal used it to build cities against pressures, harvesting seeps for alchemical brews and swirling currents for defense. Children learned it in schools before magic bloomed at adulthood, and monsters—who were but people from another view—added their clicks to dialects.
The moral of the story is that words from the depths must be spoken with care, for they bind not just sounds but the endurance of all, and misuse swirls destruction upon the speaker and the sea alike.
