Behind the scenes
Reality Z-25 31-H, whose name was only used fugitively in Singularity War, has also been referred to behind the scenes by Paul Hoppe as “the Beholderverse”. It has, over the years, turned into something of a webcomic shared universe, being the setting not only of Hoppe's works in The Cosmic Beholder, but also of Jay Epps's Kaza's Mate, Gwenna and of James Bridger's Kate Five and Section P.
In the author's notes for PROSE: Truth in Labeling, Scott Sanford noted that the story's superhero setting “might not be far from Reality Z-25 31-H or some Marvelous settings”.
