Transdimensional Void Runners

Transdimensional Void Runners is a "multiversal" scenario involving various parallel universes. Certain sects/factions of the Hesychast Order in the Universe of the Magisterium have discovered a paranormal occultic ritual (psychic with the powers of the mind or a more purely magical/theurgical/supernatural power soucre) that allows them to jump to various versions of the planet Earth in various universes.

These monks and nuns obviously intend to export the Magisterium's influence to these new Earths in new universes.
