The Scouring Blight (Apocalypse Myth)

"When the sage Fiver Cecily asked the Prince of Rabbits why, as a rabbit in his prime, does he not produce children, the Prince confided that he did, once, but does no more, as those he had were not quite as fleet as he, and there were times when they could not outrun their fate as he could. When Fiver cajoled him into saying more, the Prince let slip two things only: that there is a side of the Briarpatch, opposite the Garden, equally far from the Prince's influence, where the briars have not yet regrown and the effects of the blight remain; and that it is the nature of a hare to be swift enough to jump through the fire that scours the underbrush, where so many other creatures that would have dwelt beyond the briars could not."
Bastet of Palimpsest sang the song of the Scouring Blight in a Legend Lore spell compiling the existing myths of the Apocalypse.
