Instruction: Humans vanished 7,000 years ago. Their rigs, ships and machines did not stay empty: outlaw and zealot Pals moved in and kept building for centuries. Treat each place below as a human structure with a Pal settlement grown on top of it. Companion to World Info, section 5 (towns and guild halls).
Rustwater Barge Rig. Human oil barge in the eastern channel, pumps still running. The Iron Syndicate built a floating factory on its deck, worked by enslaved Pals and guarded with salvaged guns.
Blacktide Platform. Deep-sea human drilling platform in the far south-west, grown into a rusted town on stilts. The Apex Guild uses it as a tribute vault and a prison for those who refused to pay.
Crash Ship Bay. A huge human vessel ran aground here. Pal pirates moved into the wreck and built a full pirate harbour out of it, dressing and talking like the pirates in human adventure stories.
Desert Ship Bay. Human cargo ships left sitting in the sand when the sea drew back. Gritfang smugglers use the hulls as warehouses and a hidden port for the Rust-Dune Black Market.
Gritfang Lookout Ridge. Gritfang Outpost and its lookout tower, watching the eastern sea lanes.
The Scrapyard Coliseum. Arena welded from human stadium seats and ship plating. Pals mixed up human sports and gladiator films and now run ranked fights open to any guild or gang.
Masters' Beacon. Loyalist islet. Zealot Pals keep a human signal tower running, repeat its recorded message as a prayer, and wait for "The Masters" to answer. Hostile to anyone who touches the machinery.
Terraria Breach 1: Crimson Shoal. Islet with red sand where Tides of Terraria monsters come in with the tide.
Terraria Breach 2: The Rift Isle. The first and largest breach. Holds the Terraria Rift and the Palbox Glitch; the wrong-looking terrain spreads a little each year.
Terraria Breach 3: Hallowed Reef. Pastel, glittering and just as hostile. The Gritfang dump prisoners here.
Frostshard Floe. Pack ice north of the Astral Mountains with a human research buoy frozen in, still blinking.
The Stray Floe. An iceberg that drifted south and will not melt, even near the volcano, because of something human-made frozen in its core.
The Void Scar and Abyssal Spire Grounds. Not Pal-built and not human-built. See World Info for the Void Walkers and the Abyssal Spire.
