The Great Parch is the burning heart of the Realm of Fire, a vast continent of cracked plains, smoking volcanoes, and rivers of molten rock where the very ground seems to smoulder underfoot. Its shores are lapped by burning seas, its horizons ringed by ash-clouds, and clean water is rarer than gold, so that men wage whole wars over a single wellspring or working realmgate.
In the Age of Myth, Sigmar and the smith-god Grungni raised gleaming kingdoms across the Parch, only to see them drowned in blood when the servants of Khorne claimed the realm for the Skull Throne. From the ashes of that ruin, the Cities of Sigmar have clawed back a foothold, their basalt-walled bastions like Hammerhal Aqsha and Brightspear pressing outward mile by bitter mile into the scorched wilds.
Every step of that reconquest is contested. The war-hordes of the Orruk Warclans rampage across the Flamescar Plateau, daemons haunt the volcanic wastes, and rival warlords carve out kingdoms in the ash. The Great Parch is a crucible in the truest sense, a land that tempers the bold and burns away the timid, where the fires that forge the free cities' courage are the same fires that would consume them. Here, more than anywhere in the realms, survival is a thing wrung daily from the flames.
