Dimension 77
From Jenny Everywhere Wiki
Dimension 77 was a universe where, although humanity had largely forgotten it by the 21st century, “the old tales [were] true”, with such creatures as Leprechauns and Brownies being a reality. For example, one version of Jenny Everywhere was acquainted with the Lurigadawne of Tipperary, native to this dimension. (PROSE: The Interlude of Jenny Everywhere)
