Inter-dimensional Leakages

Inter-dimensional leakages are small tears in the fabric of the multiverse which can cause the movement of both objects and living organisms between universes.

Formation
Though the cause of leakages is largely unknown, large spikes in cosmic microwave background radiation (CMBR) is known to precede their formation. This can allow those with the proper instruments to predict the time and location of a leakage occurring, though their temporal and geographical accuracy is shoddy at best.

Classification
There are three main classifications for a leakage. These are:


 * Class 1 - Minor leakage. These are quite small and mainly result in the transference of small objects and are only preceded by a small spike in CMBR, making them largely undetectable until after the leakage has occurred.
 * Class 2 - Larger leakages that can cause small groups of people to cross into another universe. These are the most common class.
 * Class 3 - Universal leakages that result in the merging of two or more universes into one. These can have next to no effect or have apocalyptic consequences.
