Jointly administered by the Shogunate High Court of Waves & the Imperial Pearl Ministry
Restricted Maritime Zone — Unauthorized Approach Is Treason
The Privateer Admirals each command vast territories, but all three fleets ultimately anchor their authority—and their power—at one place:
A colossal tri-fortress naval complex built upon three fused volcanic islands, reinforced with pearlstone, Meito wind-shields, and Kokuto impact bracing.
The Bastion is the single most heavily defended maritime structure in the Western Ocean—part fortress, part city, part ritual ground.
It is said:
“If the Trident Bastion falls, the Western Ocean falls with it.”
The Bastion is divided into three sweeping complexes, each corresponding to the domain and ideology of one Admiral. Every section is massive enough to serve as a standalone naval base, yet together they form a tri-lobed citadel shaped like an enormous, partially submerged trident.
Domain of Admiral Tetsu-no-Mura
A fortress of black basalt and froststeel plating.
The harbor is carved directly into the volcanic foundation, producing an eerie cavern-port where his silent Glacier Line ships dock like slumbering beasts.
Key Features:
The Frozen Drydocks — climate-controlled to replicate Polar conditions
The Silence Courts — judicial platforms where punishments are passed in total quiet
The Eightfold Gate — layered portcullis that can withstand a Large Pearl detonation
No one speaks loudly in the Iron Ward.
Even the sea seems to whisper.
Domain of Admiral Shin Reikado
A labyrinthine pearl-lit administrative city rising in perfect terraces.
Its green-white stone, polished to mirror sheen, reflects both the sun and the political ambitions within.
Key Features:
The Auditor’s Tower — tallest spire in the Bastion; monitors all fleet movement
The Concord Reservoir — storage for all taxed pearls awaiting redistribution
Hall of Ledgers Eternal — records every legal ship, cargo manifest, and bounty
The Jade Archivum is quieter than a court yet busier than a market—exactly the environment Shin thrives in.
Domain of Admiral Rokuji “Black Anchor” Gai
A sprawling war foundry where storms are chained and weapons are born.
Forged metal, Pearlwork engines, and thunderstone plating form an industrial labyrinth that never sleeps.
Key Features:
Stormbind Crucible — the only known facility capable of stabilizing Meito storm pearls
Hammerfall Pier — berths The Hammerfall and its hurricane escorts
Memorial of the Broken Seas — names of crews lost battling Buccaneers
The Anchor Forge smells of metal, storms, and old war stories.
At the exact meeting point of the three domains stands the Trident Spire, a towering neutral ground governed by both nations:
Top floors: Hall of Waves (Shogunate authority)
Mid floors: Pearl Ministry offices (Imperial Dynasty)
Lower levels: Joint Tribunal for Privateer disputes
Only Admirals and Crown-ranked officials may enter the upper chambers.
The Spire also houses:
The Grand Resonance Bell (rings only during national crisis)
The Admiral Strategy Vault
The Trident Map, an evolving pearl construct tracking all major maritime movement
When the bell tolls, every captain in the Bastion kneels.
It has rung only three times in recorded history.
Surrounding the Bastion is a ring of defensive innovations unmatched in the world:
Meito arrays able to conjure directed lightning or pressure waves.
Kokuto explosives that lie dormant until sensing enemy resonance.
A massive, layered ward generated by thirty synchronized Medium Pearls.
Cloaked Privateer cutters prowling in abyssal trenches.
No pirate fleet has ever breached the outer ring.
Three Buccaneer armadas have tried.
None returned.
The Trident Bastion is more than a base—it is:
A symbol of Shogunate authority
A hub of Imperial bureaucracy
A fortress against piracy
A training ground for elite Privateers
A ritual site for ancestral sea worship
Every Pearl, every ship, every trial, every verdict that shapes the Western Ocean eventually passes through its gates.
If the Admirals are the ocean’s rulers,
the Trident Bastion is their throne.
