Squarely in the center of the Sea of Lament, the Shattered Arch rises from the waves like the broken spine of a drowned giant. It is a chaotic archipelago of jagged rock formations, sea stacks, narrow channels, and islands ranging from barren outcroppings barely large enough to stand on to landmasses capable of supporting permanent habitation. The Arch is believed to be a fragment of the original Etherea that neither sank nor drifted to either continent during the Split—it simply broke apart and stayed where it was, a shattered bridge between two worlds.
The geography of the Shattered Arch is a navigator’s nightmare. Channels that appear passable on a chart may be blocked by rock formations invisible at high tide. Currents within the Arch are chaotic, influenced by the surrounding deep water and the irregular seabed. Fog is common. The combination of treacherous navigation, abundant hiding places, and a central position astride the main shipping lanes has made the Shattered Arch the natural home of piracy on the Sea of Lament.
Port Splinter
The largest settlement in the Shattered Arch is Port Splinter—a chaotic pirate haven built across several interconnected islands in the heart of the archipelago. Port Splinter is not governed in any conventional sense. It operates on a volatile equilibrium of competing pirate captains, black-market merchants, and the kind of informal rules that emerge when everyone involved is armed and no one recognizes external authority.
The settlement is built from whatever was available: salvaged ship timber, stolen cargo crates, volcanic rock quarried from nearby formations, and an architectural philosophy best described as ‘functional indifference to aesthetics.’ Rope bridges connect the islands. Docks are crammed into every available cove. Taverns outnumber all other buildings combined. The air smells of salt, tar, and bad decisions.
Despite its lawlessness, Port Splinter serves a function in the broader maritime ecosystem. Stolen cargo is fenced here, making it recoverable by those willing to pay or fight for it. Information flows through Port Splinter faster than through legitimate channels—if something has happened on the Sea of Lament, someone in Port Splinter already knows about it. And for those seeking passage to places that don’t appear on official charts, Port Splinter is the only port that will take the contract.
DM Truth: Port Splinter’s Hidden Value
Port Splinter’s pirates have been increasingly targeting Glowstone shipments since the reactivation. This is not random opportunism—someone with resources and a plan is offering bounties for Glowstone cargo, paying well above market rate. The buyer’s identity is unknown to most captains, who deal through intermediaries. The Cult of the Veiled One has agents operating in Port Splinter, though whether they are the buyer, a competing interest, or both is deliberately left for individual DMs to determine.
Port Splinter also sits directly above some of the most significant Deep Ruins in the Sea of Lament. The original Etherea’s infrastructure—roads, foundations, possibly entire structures—lies beneath the Arch in better condition than anywhere else, preserved by the shallow waters and the protective ring of the archipelago. The pirates don’t know this. Scholars would kill for the information. Someone, eventually, will dive deep enough to find out.
Adventure Hooks: The Shattered Arch
A merchant house has hired the party to recover a specific cargo stolen by Arch pirates: a sealed crate that was supposed to reach Runewick quietly. The merchant will not say what’s in it. The pirates who took it have opened it, and now they’re asking questions that suggest the contents are far more significant than stolen goods.
A pirate captain in Port Splinter has put out word that she’s found something underwater—something big, something old, and something she can’t move without help. She’s offering a full share to anyone capable enough to assist. Three previous groups accepted the offer. None have been seen since.
The party needs passage to a location that no legitimate captain will sail to. Port Splinter is the only option. The price isn’t gold—it’s a favor, payable at the captain’s discretion and at a time of the captain’s choosing.
