Rift
Rifts were gaps in the fabric of reality, which could open spontaneously from one universe to another. However, they were unpredictable and dangerous. (COMIC: The Beginner's Guide to Multiversal Theory) Rifts could appear as a result of “major disturbances in the fabric of reality”. (PROSE: Rifts Crisis Officially Over!)
Some Rifts worked as dimensional portals, (PROSE: Rifts Crisis Officially Over!) with even Jenny Everywhere able to use them, (COMIC: Untitled) but they would also often interfere with the ability of other methods of interdimensional travel to function in proximity to the Rift, (PROSE: Rifts Crisis Officially Over!) including Jenny Everywhere's shifting. (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids)
Rifts were ordinarily rare, (COMIC: The Beginner's Guide to Multiversal Theory) but during the Rifts Crisis, an “epidemic” of them spread throughout the Multiverse, destroying or endangering countless universes. It was eventually stopped with the destruction of Mandragora's Machine, which was accelerating the spread of the Rifts, combined with the uses of Prisms to counteract most of the existing Rifts.
