Event Type: Conquest & Enslavement / Origin Trauma
When the Void Leviathans first breach into realspace along a chain of ocean worlds, the Tanyon‑Unin are still a pre‑industrial littoral civilization—sail‑fleets and carved outriggers plying coastal currents, waterwheels grinding grain along estuaries, and sprawling city‑reefs grown into continental shelves. Their lives are bound to tides, clan law, and the seasonal pulse of the sea.
The Leviathans do not arrive as lone titans but as architects of occupation, bringing vast, bio‑engineered drone‑broods and atmosphere‑skimming tendrils that unfurl across the skies. Within a few Cycles, they seize key harbors, delta mouths, and reef‑throats, converting familiar coasts into extraction pits and spawning‑basins. Tanyon‑Unin communities are not simply conquered; they are repurposed—clan labor conscripted to maintain the Leviathans’ organic infrastructure, dredging biomass, hauling stone, and feeding living engines they barely comprehend.
In Tanyon‑Unin oral history, this entire era collapses into the First Drowning of the Shores: generations defined by forced sacrifices to abyssal pits, skies darkened by Leviathan silhouettes, and the slow, degrading replacement of clan law with alien quotas measured in biomass and stone. The old words for justice and custom erode, replaced by terms for rations, yields, and acceptable losses, all dictated by entities that may never have learned their names.
Shoreline Civilization Under Siege
The Tanyon‑Unin begin as shore‑bound, reef‑anchored societies, not voidfarers. Their first real contact with the wider cosmos comes as predation from above and below, not enlightenment or trade.
Leviathans as Occupation Ecology
Void Leviathans don’t just attack; they terraform social and physical space into extraction organs—drone hives, tendon‑piers, and flesh‑engine cranes that reshape ports and reefs into parts of a larger feeding body.
Clan Law vs. Quota Law
Traditional Tanyon‑Unin clan law is quietly supplanted by Leviathan accounting: duty becomes quantified in bone‑weight and stone‑tonnage, replacing reciprocal obligation with one‑sided exaction. Oral epics remember this as a spiritual as well as physical drowning.
Tanyon‑Unin Ancestry/Background Anchor: Explains why later Tanyon‑Unin cultures are obsessed with sovereignty over coasts, abyssal trenches, and sky‑lanes, and why many bear scars—physical and cultural—from enforced collaboration with alien biostructures.
Void Leviathan Threat Profile: Establishes Leviathans as system‑scale occupiers, not mere kaiju; their power includes bio‑industrial logistics, labor regimes, and psychological domination.
Moral & Historical Weight: Gives PCs from this lineage (or worlds like theirs) a deep well of ancestral resentment, ritual, and taboo around forced quotas, extraction economies, and sacrificial “infrastructure projects.”
The First Drowning of the Shores is where the sea itself turns collaborator: Void Leviathans reshape coastlines, labor, and law until every tide pulls toward their hunger—and the Tanyon‑Unin learn, in blood and silt, that survival means never again mistaking quotas for justice.
The mythic prologue for campaigns set among modern Tanyon‑Unin descendants.
A time‑echo or Rift‑vision PCs experience when investigating Leviathan ruins or deep‑sea anomalies.
A cultural touchstone invoked by elders when warning against new “alliances” that smell like quotas in disguise.
This event is the Tanyon‑Unin’s foundational trauma: the moment Void Leviathans turn their shore‑civilization into a conscripted extraction organ, and “law” becomes biomass quotas.
