Destructive And World-Changing Events

History has turning points like the agricultural revolution and the World Wars. Such world-changing events are reflected in mythology, e.g., by the Flood, the Ragnarok and Armageddon, and also in modern works of fantasy:

in DC Comics, the Crisis on Infinite Earths destroyed the multiverse where characters who were fictional on one Earth had been real on another;

in Black Easter and The Day After Judgment by James Blish, the demons win Armageddon, thus changing the theological regime;

in Jerusalem by Alan Moore, a chimney called the Destructor symbolizes the destruction of dreams and hopes and affects the way that people think so that their ghosts and memories smoulder and Heaven itself burns.

Events on these fantastic realms affect the everyday world:

"'If Mansoul itself wiz on fire up in this new century, then wiz it any wonder you've got living people doing stupid bloody things like that?'"
-Alan Moore, Jerusalem (London, 2016), p. 727.

The speaker nods towards a suicide bomber eternally exploding in the hereafter.
