Schematic map of Hollow Heart.
A black wound in the hills where the earth never quite cooled. Obsidian fields crunch underfoot, vents breathe sulphur, and hornosaurs bask on stone too hot for anything else to bear. Miners brave it anyway — the coal and iron all but mine themselves.
Travellers report hornosaurs and spiders.
Gatherers come for coal seams, iron ore, and quarry stone.
