Introduction
The term "villi" refers to a creature of the species Homo villius, a possible subspecies of Homo sapiens. Sightings of these elusive and mysterious creatures have been reported by many different beings from numerous dimensions of all types. However, it's likely that no one from present-day Earth really knows what a villi looks like, as no known human has ever actually seen one. The varying pieces of information we have on villis come from many different sources who offer their own physical descriptions of these creatures. Each description tends to manifest villis in its own particular way, which makes it hard to know for sure what a villi truly is.
The concept of the villi was originally introduced by the Irish game developer Terry Cavanagh when he created the popular video game "VVVVVV." The game provides a sort of template from which people can formulate their own opinions on the nature of the villis. The game presents the villis as monochromatic stickmen in a 2D enviroment, and this general picture is the basic idea of what villis are. However, some believe that villis are actually more complex than what they look like in VVVVVV, and many experienced artists draw them as humans, or at least humanoids.
Putting speculation aside, however, all villis share one definite characteristic that indentifies their species; they have the ability to flip gravity rather than jumping. Besides that one fact, the villi is basically an image of opinions. Terry's original game, VVVVVV, is generally accepted as the main source of canonical information about the villis, but it is no encyclopedia. There is much room for interpretation, and there are tons of various fan-made drawings, stories, comics, etc… that prove this.
Ultimately, I believe that the universe is infinite, and all the fan-made stories about villis are true, in their own dimensions. This fanfic contains my stories, and my opinions. The villis are presented here as creatures that look just like humans, but with internal flipping organs that allow them to flip gravity.
Unlike the villis in VVVVVV, the ones here have genitals, and this fact is what makes this fanfic's general focus on villi sexuality possible.
