The first Corpse Carts came about during the year of 1111 IC, when the Chaos Moon, Morrslieb, showered down great chunks of warpstone meteorites upon the lands of Sylvania. The citizens of Sylvania during that time were wracked with the horrors of the Black Plague, a powerful disease unleashed by the vermins of the Skaven Under-Empire in an effort to weaken the Empire of Man before their inevitable surface invasions. When fragments of warpstone were scattered all across Sylvania, the bodies of these victims became imbued with large amounts of Dark Magic.[1a]
