Europa:

One of the several moons surrounding the planet Jupiter in the Milky Way galaxy. Former home of Ruby Tuesday, Terra-born Galactic Gumshoe, in the early 25^th century. Once thought of as an icy, inhabitable world, now scattered with numerous Terran colonies, along with many other forms of life. Houses a fairly advanced society, technologically. Current status unknown.

Dong-A-Long:

A small planet (approximately the size of Terra’s moon) formerly located along the periphery of the solar system of Saudi Asteroidia. The green-skinned, humanoid natives had no written language and lived a fairly peaceful life until somewhere around 2400 A. D., when a missionary introduced Angloese to the primitive culture.

The Dong-A-Longese came to idolize the Terran detective Freddy Fong, as he was shown to them by the missionary, who had a major flaw in his teaching methods. The natives attempted to become like Freddy Fong (or the Great Fong, as he became known), which would be understandable except for one small problem:

The planet Dong-A-Long’s system of thought was a group-mind, meaning if one person knew something, all others knew. Consequently, they became "a planet of detectives with nothing to detect." The group-mind began to split into fragments, and in an attempt to save the planet, the people allowed a small number of themselves to operate on the periphery of the group-mind, meaning their thoughts could not be detected. This backward planet barely got by for several decades until the arrival of Ruby Tuesday, a gumshoe who brought a new sense of hope to the people of Dong-A-Long.

After Ruby’s brief stay and departure on the planet, the natives put together a mental collaboration to free the world, and surprisingly, they succeeded. Ruby Tuesday was left having a small planet following her around, together solving the mysteries of the galaxy. However, since Ruby Tuesday and Dong-A-Long were never mentioned after their last appearance, the status of both is difficult to determine.

Cleo:

Formerly assumed to be a small, barren, uninhabited planet located near the periphery of the solar system Saudi Asteroidia, its discovery credited with the Colonel Abullah Abdullah. It vanished from its orbit in the year 2433 A. D., and the owner of the solar system offered the reward of the whole planet when it was returned.

However, the planet Clio never actually existed. It was, in fact, a holographic projection created by the Colonel, and the whole chain of events was an excuse to gain control of the nearby sphere of Dong-A-Long. Ruby Tuesday was snared in this nasty plot, but she managed not only to foil the Colonel’s plans, but also ironically freed the planet Dong-A-Long before any planet-liberating technologies were even developed.

Aurora:

Planet of unknown size and location. The highly intelligent inhabitants devote their culture to aesthetics, believing that every aspect of life is art. Though this may seem impossible to form a stable society at first, the Aurorians have maintained a thriving society even after the Age of Cybernetics. The people are humanoid in appearance, with large eyes and long, slender fingers. They are strangely beautiful, which can explain why Ruby nearly fell in love with one of them.

The natives of Aurora also have a group-mind intelligence, ergo, if one knows, all know. Unlike the planet Dong-A-Long, Aurorians can live separated from the planet and still communicate with the populous still on-planet.

Three people of Aurora have played a significant role in the life of the female Terran detective, Ruby, an inhabitant of the planet Summa Nulla. An Aurorian named Monet visited the planet during the time era Ruby 1 took place. He allowed Ruby to travel with him to Casino City, a location in the Utopias. From there, they parted. Ruby tried to meet him again when she learned that Monet knew about the place titled the Black Star in order to learn more about it, but when Ruby arrived where she expected to find him, in the Hall of Shadows, she found him dead. Ruby barely escaped his assassins (the Slimies, as it turned out) with her skin and reported his death to the Aurorian Embassy. This is the last we hear of Monet -- for the moment.

Shortly after this tragedy, Monet’s sister, Moonbeam, an Aurorian warrior, meets Ruby and tells her about her plans to revenge Monet by killing off the last of the Slimies. The two have a huge shoot-out with the foul creatures and succeed -- however, Ruby’s final "I think..." after Moonbeam asks if they have truly snuffed them all leaves an ending screaming for a surprising sequel.

In the beginning of Ruby 3, Ruby encounters an individual whom she immediately mistakes for Monet, back from the dead. He is an Aurorian, but it is not Monet. The alien introduces himself as Man Ray, one of Monet’s closest friends, a representative of the Aurorian Embassy. Man Ray hires Ruby to find the source of the dark force entitled Zumzamin, which is increasing rapidly and originating chiefly from Summa Nulla. The sudden increase is dubbed "a threat to aesthetics" by the Aurorians, and Man Ray is voted the person to report the incident to a peeerson who can find out why.

Near the end of Part 1 of Ruby 3, Man Ray attends the Digital Circus with Ruby to help in the assault upon Magnifico, City of Malls, the location where Zumzamin is the most powerful. Surprisingly, even though he is very skeptical at first, Man Ray appears to gain a sense of humor, a characteristic uncommon among Aurorians. When he appears for the last time at the final celebration of the circus, he invited Ruby to visit his home planet, and comments on Ruby’s own home world.

During the time Ruby is in the Invisible World in Ruby 3, she discovers Monet did not actually die in Ruby 1. When she first meets him, she thinks that he is a Time Suspender, one of the humans who knows the secret of eternal life, but much later, after she falls madly in love with Monet, Monet leaves her and she nearly has a nervous breakdown, she is told by the bartender at the Astral Bar and Grill that Monet is really a Twilight Master, a person who serves both sides -- a typical occupation, perhaps, for a planet whose inhabitants see the Middle Path and no separation between dark and light.

Even though Ruby is very frustrated, she manages to go on, and asks herself why people spend so much time on relationships anyway, and as the bartender says: "He showed you it is possible to give yourself to someone without losing yourself."

Potato (NOT pronounced the way you think, spelling uncertain):

The smallest of Summa Nulla’s three moons. Its name fits its description, similar to Terra’s moon but probably much smaller in size. Formerly the location where Slimies were genetically engineered and assigned tasks, now completely barren, as far as we know; the only moon, with the exception of Sonto Lore, that Ruby has set foot on.

Sonto Lore:

The former fourth, largest, fifth-dimensional moon of Summa Nulla. Long considered to be a myth, though for some it truly did exist. When the infamous archeologist Marimba Mombo gave Ruby a white gold coin which originated from Sonto Lore, this turned the tables on the facts. The planet began evolving dimensionally, fast enough to be noticed, but slow enough to cause emotional turmoil.

A gigantic oscillating machine was built on the moon to accelerate the evolution by the ascended Terran scientist Nikola Tesla and And/Or, a young, open-minded tecchie from Summa Nulla, but unfortunately, the vibrations created by the machine were so great that the moon crashed into the planet, creating two new planetary bodies. Sonto Lore merged with 5-D Summa Nulla, whereas 3-D Summa Nulla stayed the same.

Ruby and her companions became inhabitants of 5-D Summa Nulla, but like everything in life, this heavenly life was only temporary, and soon, all the inhabitants "fell back down to earth," as is revealed in Ruby 5.

Orpheus:

One of Summa Nulla’s three moons. Size in relation to other moons and orbital map unknown.

Shangri-La:

One of Summa Nulla’s three moons, often called the "muse moon" by visionaries and mystics of the planet (reference: Ruby 4). Size in relation to other moons and orbital map unknown.

Terra (called "Earth" in Ruby 1-5):

Ruby’s and possibly other residents of Summa Nulla’s former home. The time of their departure from the planet is uncertain. In the late 21^st century, Terra is in a bad state, according to the continuous stream of reports.

In Ruby 5, it is mentioned that Disney purchased Terra and renamed it Planet Disney, with the excuse that "everyone wanted to live in a fantasy." This may be laughed at by some people, but look again at the present. Are we that far from that?

Rijaka-Koonka (spelling uncertain):

This planet makes its debut in Ruby 4 and neither it nor its inhabitants are mentioned again. Probably for a good reason.

Rijaka-Koonka is a 4-D sphere populated by half-human, half-lizard creatures known as reptoids. This fairly ugly, muddy planet has been exhausted of nearly all its natural resources and the inhabitants have survived by cloning themselves and draining energy from other planets by means of 4-dimensional implants, or "parasites," as some call them.

One of their targets for colonization was the planet of Summa Nulla, mostly because the world was dividing and there was a lot of emotional turmoil to feed off. However, when S. N. split in two (not physically, but in terms of dimensions), creating a 3-D world and a 5-D world, the question of whether the reptoids are still feeding off the 3-D planet is still unresolved.

The former occupants of 5-D S. N. have recently fallen back "down to earth," and there has been no mention of Rijaka Koonka. Perhaps the planet has totally collapsed, or maybe the inhabitants have moved on to another planet. Perhaps only time will tell.

Jar-Jar 3:

A five-dimensional world of uncertain location. Invisible to beings native to the lower worlds (4-D, 3-D, etc.). Very small in size, completely covered by large roots which appear to have no definite source -- at first. The one mountain on Jar-Jar 3 contains a cave said to be filled with rare memorabilia from all over the solar system. Usually a native alien is present to deal in any trading or haggling over goods. (Note: there are rumors that the cave is the mouth of a huge monster that covers the whole planet. There is no good evidence of this, however, and visitors are reminded that the so-called monster will not attack unless it is provoked).

Illuboo Roi:

A mostly desert planet inhabited by pale, pear-shaped aliens with long arms and four feet, two of which they usually keep "tucked away." They are surrounded by shimmering auras called the Nac-cree, which, roughly, contain their thoughts, and can be experienced by other individuals, even outsiders.
