The Void
The Void, also known as the Void Between Worlds, (PROSE: Lord Thymon and the Department of Problem-Solving, etc.) the nothingness beyond existence, (PROSE: Where Is Everywhere) the Howling Void, (PROSE: Magic Trick, etc.) the Outer Void, (PROSE: Family Business, etc.) or the Interdimensional Void, (COMIC: 24 Hour Comic 2019, PROSE: Who Laws the Lawyers?) was the empty, liminal “space” in-between the various dimensions making up the Multiverse.
Cosmology
Contents
The Void was not as empty as the name might have suggested, constantly being criss-crossed by an arbitrary number of dimensional travellers in various contraptions. It was also the forced residence of various eldritch beings who had been banished from their native realities. (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids) For example, the Destroyer, a being which had threatened the existence of the proto-multiverse at “the beginning and end of everything”, was banished into "the nothingness beyond existence" by the Defender as her last act before she became Jenny Everywhere. (PROSE: Where Is Everywhere)
The Void was even, somewhat paradoxically, home to a few landmarks, such as an Interdimensional Tavern, (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids) the Interdimensional Casino and the Interdimensional Hotel. They were permitted to exist inside the Void thanks to the unified perception of space, time and thought that was guaranteed by the Embodiments, imposed on the senses of other beings traversing the Void by the power of the three Embodiments. (PROSE: The Grand Multiverse Hotel)
Because the Void was non-Euclidean and had more than three or four dimensions, it was possible to “pick a notional direction that [was] ‘away from any universe’ and ‘away from any landmark’”. Going “far enough” in that “direction” would lead to one eventually “disappear[ing] into a dimensional stratum of absolute nonexistence”, known as the Null, variously understood as an aspect of the Void or a non-realm “beyond” the Void. (PROSE: Who Laws the Lawyers?)
Appearance
Because the Void had no existence of its own, it did not “look” like anything. Attempting to look out the window while flying through the Void on an interdimensional shuttle, Wendy VII “could see… nothing. More than darkness or an endless whiteness — the space on the other side of the the window was blank. Her senses were refusing to perceive it”. Indeed, theoretically, two people passing through the Void might pass right through each other, unable to touch or perceive one another, if their perspectives weren't “synched”. However, because the Embodiments imposed an illusory “consensus reality” on weaker beings passing through the Void, it could be perceived as a “place” to one degree or another. (PROSE: The Grand Multiverse Hotel)
It could, for example, be visualised as a brownish expanse through which landmarks like the Interdimensional Tavern, and the various travellers and abominations floated weightlessly. (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids) It could also appear as an infinite space with a pinkish or purplish hue, criss-crossed by an intangible electric-blue grid, (COMIC: The Beginner's Guide to Multiversal Theory) or as a more fluid-looking vortex with similar hues.

Dimensional travel
Many methods of dimension-travelling, such as those utilising Void Ships, relied on physically crossing through the Void on the way from one world to the next. (COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids)
Jenny Somewhere found it easier to shift to a specific location if she started from the Void, rather than trying to shift directly from one world to the next, (PROSE: The Disappearance of Jenny Everywhere)
Jenny Everywhere most often used the Infinite as a “buffer” when shifting from one universe to another, in contrast to other dimensional travellers who habitually used the Void for this purpose. (COMIC: The Beginner's Guide to Multiversal Theory) However, other shifters like Greta Överallt and at least one version of Jenny Anywhere routinely travelled through the Interdimensional Void.

Behind the scenes
The “Void Between the Worlds” is a standard science-fiction concept. Notable uses of it include the Lovecraftian mythos (which calls it the Audient Void) or Doctor Who (where it is known as "the Void” or “the Howling”). The version of the Void seen in COMIC: Jenny Everywhere Meets The Crew Of The Copper-Colored Cupids was, of course, the version recurring in the solo adventures of The Crew of the Copper-Colored Cupids.
