Introduction

The climate in Errata is hostile. They still call it “weather,” but the word no longer has any real familiarity. Errata’s sky is a wounded engine. Its gears have been stripped. Its timing has long since broken.

Heat pools on the ground like standing water, then lifts in invisible tides that warp the horizon. In the Lowlands the winds arrive without pattern, baring teeth of glassy dust; then they vanish, leaving a silence so absolute it bruises the ears.  On the Plateau the prevailing winds come in from overheated Great Dust Basin, and carry with them giant clouds of dust and silt.  While in the Highlands heat can turn to chill in an instant, as the high winds rise along the walls of rock and rapidly cool.

Mid-day temperatures are avoided for heat, while at night they pitch‑roll thirty or more  degrees, depending on location. No two regions share a forecast, because there is no global system left to predict—only pockets of turbulence carved by wrecked oceans that slam against progressively higher stone rises.

Silt Storms

A silt storm comes on slowly, and always from the direction of the Great Dust Basin. The wall of dust can be seen for miles. When it arrives, fine alkali dust is blown with enough force to penetrate most cloth filters, clogging them. Vision drops to almost nothing. Exposed skin burns. Smart travelers drop low and seal tight. Entire towns close their gates.

Sandstorms

Unlike a silt storm, a sandstorm is sudden and arrives from the dunes. Winds are higher, and the particulate is not as fine. While breathing is not impaired, uncovered skin becomes damaged, the longer it is exposed the more raw it becomes, until there’s no more skin left— only bone.

Scirocco

Errata’s scirocco move low and fast—amber, abrasive, and thick with lifted dust. Folding the air into motion, shearing scrub flat, and grinding across open ground with heat-born force, everything it touches shifts. Nothing in its path stays whole.

Electrical Storms

Electrical storms can form with or without cloud cover, when dry pressure breaks and current builds across exposed terrain. Lightning moves sideways, not down—traveling cliff edges, and industrial alkalines in the soil. Static crawls through the air. Caravans travel with deployable lightning rods to manage sudden storms.

Thermoclines

Thermoclines occur when in air where heat and pressure no longer agree. When this happens at high elevations, the temperature collapses. Sound changes. Breath catches. Birds vanish. It is not a storm, but the moment before one becomes inevitable.

Flash Floods

Flash floods carve down from the highlands into narrow valleys and outwash gullies, carrying debris, silt, and clay with enough force to tear loose stone. They form without rain nearby, born hours earlier in distant mountains. By the time they reach the flats, they’re fast, shallow, and lethal—brief rivers that vanish as quickly as they form, leaving carved channels and standing mud behind.

Deluge

Heat surges up the valley in silence, hits the cold wall left by the thermocline, and is pushed below it.  When this happens, the winds surge and rain falls hard, fast, and cold, hammering into stone and clay. Paths turn to water channels, and smart Highlanders take shelter, knowing that cold air and wet clothing is guaranteed death.

Everything Comes With a Cost

Lightning has become a refugee, untethered from rain. Bolts cut sideways through dust laden air, drawn from the static that builds in alkali flats and bone‑dry silt, and then is distributed across the landscape in the wind.

Thunder comes seemingly from nowhere and everywhere at once—sonic booms that rupture the lungs of unshielded travelers.  Water still falls from the sky in the mountains, but it comes in deluges that are gone as quick as they arrive. The parched land, unable to hold the water it so desperately needs, quickly turns to floodwaters which settle into pools at the mountain bases.  Pools that quickly evaporate.

Scirocco and tornado are familiar to all travelers, and feared, while great walls of dust and debris blow across the Plateau from the Basin, gaining mass before engulfing towns in sandstorms that can take flesh to bone in minutes.

In the Great Dust Basin it is more calm, but that isnt due to better conditions. Heat can be so severe all life seeks shelter, and the heat is constant—as is the silt. It gets everywhere, making fine mechanical devices wear quickly and requiring regular replacements from the Plateau for essentials to keep the water pumps running.

Survival is now a negotiation between the sky and the sand.

Dryrunner caravans pace their slow marches to the nearest water source, always moving and powering great cooling engines inside their wahka. These mechanical lungs allow existence even in the hottest reaches. But the wahka must keep moving.  The lungs don’t breathe when the Run stops.

Plateau cities bleed energy into giant water pumps and environmental regulators for those wealthy enough to afford them, while the masses work for their small share, and just as often contend with shortage.

Highland citadels work the last glaciers in an existence that may seem to hold every advantage, if it were not for the land itself exacging its own toll. Every Highlander knows the quakes, and fears them. Almost as much as they fear what lurks in the forests that separate their lands from the Plateau.

Every clan, faction, and drifter has learned the same lesson: weather is neither forecast nor backdrop. It is the final sovereign of Errata, and it rules by whim.
