925th Universe

Jenny Over-There hailed from a seemingly-mundane universe known to Jenny Everywhere as the 925th Universe (PROSE: Family Business) where SatNavs all had knowledge about the geography of parallel worlds, hence their sometimes leading people onto roads that seemingly didn't exist. The M.F.S. office was located there, although it was unclear whether the Man in Grey was native to this world, (PROSE: The Tribulations of Jenny Over-There) having originated as the Man in Black.

Though answering to a group of eldritch entities known as the Great Higher-Ups, the Man in Grey once confessed that he did not know which Gods, if any, were actually in control of this realm. (PROSE: Lovie Dovie Stuff)

This universe was home to a version of the Land of Oz, which seemed to be a pocket reality of some kind, as it was not considered to be part of Earth. (PROSE: A Series of Queer Events, Lovie Dovie Stuff)
