The Brinemarch Run

Region: WHITEOUT CANYON REGION (Tiles: N, T, U, A&)

WHITEOUT CANYON REGION (Tiles: N, T, U, A&) The Grave Current cuts white through black volcanic stone, ammonia-laced from its source at Lake Occlusion, burning everything that grows too close. This isn't a river valley—it's a wound that won't heal. The canyon walls glow white in certain light, bleached by millennia of ammonia exposure. The basalt plains surrounding it mirror Iceland's black sands—volcanic, stark, hostile. Sparse vegetation clings to areas the river doesn't reach. Everything else is bone-white stone and toxic fog. This is the gateway to Lake Occlusion. The route up the canyon means ascending against increasingly concentrated ammonia, breathing through respirators, watching the white walls close in. Ghost canoes can navigate it—vessels adapted to the chemistry, piloted by those who know the songs. Colonial expeditions try with conventional boats and fail spectacularly. The region is arid independent of the river. Rain shadow from Elkmist Mountains means clear skies, extreme temperature swings, dust storms instead of rain. Sun-crows thrive here. The bird counter climbs rapidly with no weather relief. A& tile catches the overflow—a coastal anomaly outside the main river system, lumped here by necessity rather than logic. What you need: Ghost canoe. Respirator. Reason to risk death for answers.
