Universe (Showdown in the End Times)
In one universe, Jenny Everywhere had a shootout with the Cthulhu Kid in the middle of a desert.
Cosmology
This universe contained a desert, within which was an enormous rock formation that was described as weird and jagged.
Eldritch beings existed in this universe, the most powerful of which, the Old Ones, intended to bring about the universe's end when the stars aligned properly. (PROSE: Showdown in the End Times)
History
The universe's native version of Jenny Everywhere challenged an eldritch being known as the Cthulhu Kid to a gunfight in the hopes of forestaying the end of the universe.
Although she managed to kill or at least wound the Cthulhu Kid, it didn't help, as the stars had already aligned. The Old Ones coalesced into an alien creature in the sky above. Jenny, defiantly stuck her tongue out at the being while looking it in the eye. (PROSE: Preludes and Distractions)
