Rifts Crisis
The Rifts were rips in the fabric of spacetime which once spread like a disease throughout the whole multiverse.
The Rifts caused some universes to unravel and, at any rate, made travel between them more difficult. As a result, many versions of Jenny Everywhere temporarily lost the ability to shift and to tap into each other's knowledge, lest they go mad or fall out of reality completely; many more of Jenny's selves died than had in living memory. One version of Jenny who had retained the ability to shift investigated the Rifts' origins and discovered that they seemed to be caused by the activities of a sort of interdimensional sect called the Consistency Imperium: wherever they went, Rifts appeared or worsened.
Pythagoras-858, whom this Jenny encountered while looking for the Imperium's home base, already knew something of the Rifts, which had cut him off from his homeworld. After learning Jenny had a lead, he decided to join forces with her and the two departed to seek out the Imperium together. (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids)
