Old Ones
The Old Ones are the vanished advanced civilization of Roland's world, remembered from The Gunslinger onward through the ruins, relics, and half-working machines their fallen age leaves scattered across Mid-World.
The Old Ones stand behind nearly every ruin, wherever the desert world shows the stamp of vanished machines. Sometimes called the Great Old Ones, they are remembered as an advanced society of humans who ruled All-World thousands of years before Roland's time, raising great cities, laying roads, and building engines beyond any understanding that survives them. Their age ends in a total war remembered as the Great Cataclysm, and the poisoned lands and twisted mutant creatures of Mid-World are counted among its leavings. They never appear themselves; what remains is wreckage, half-working relics, and the unease of the people living among what they left.
