Setting

Jijo
The setting of the majority of the first two novels and the novella Temptation is the planet Jijo. Jijo was declared fallow for one million years by the Migration Institute, in order to give it a chance to recover from successive colonies, but has been illegally populated by fugitives from several races seeking refuge there. By mutual agreement they all live on one geologically active area of the planet, called "The Slope" insuring that in time all trace of their settlements will be recycled back into the planet by subduction. If this law is broken and the so-called "Sooners" refuse to return to the Slope, the penalty is death.

The Commons is a loose quasi-government on the Slope of Jijo. It is composed of members of six races: Gkek's, Humans, Hoons, Trakei, Quehen, and Urs. The Commons was formed as a unity government to stop wars that had plagued the Slope for decades. Each race has a "High Sage" that represents them on a council, and lesser sages perform various other tasks on behalf of the Commons. Other races present include Glavers, the only race on Jijo to actually progress down the devolutionary "Path of Redemption", partially uplifted chimpanzees, known as "chims", and Noor Beasts, a blend of non-uplifted root stock of the Tytlal race, and actual Tytlals passing as beasts.

The Fractal World
The Fractal World is an enormous, hollow artificial structure built around a dying dwarf star, the inside of which is used as a refuge by races in the Retired Order, or "Old Ones", that have supposedly retired from active participation in the affairs of the Five Galaxies.

Kazzkark
Kazzkark is a small planetoid, hollowed out to serve as a base for several of the Great Institutes, and a way station for travelers passing through nearby transfer points. For a time it is extremely crowded with refugees and religious fervor as the Time of Changes begins, but space tremors cause it to be abandoned shortly before it is destroyed.

E-Level Hyperspace
E-space is an off-limits level of hyperspace for most orders of life, a strange realm where thoughts can become real and mere concepts can cause real harm. Its only natural inhabitants are "memetic" organisms. They are unable to exist outside of E-space without a host organism. Members of a mysterious order of life known as the Quantum Order are known to pass through E Level sometimes.

Plot

Brightness Reef

Brightness Reef introduces the reader to the planet Jijo, a world that had been declared fallow, but one area, known as The Slope, is illegally inhabited by eight different galactic races, most supposedly seeking the "Path of Redemption", the goal of which is to devolve into a non-sapient life form, to be re-uplifted by a new patron race in the future. The peaceful, primitive society of Jijo is severely disrupted by the arrival of offworlders, first a mysterious mute human, followed by a starship belonging to the Rothen, a race of galactic criminals, and their human devotees, the Daniks. The Commons of Jijo establishes an uneasy, distrustful relationship with the Daniks for a short time, but events accelerate rapidly and it becomes clear that the Rothen are amoral, attempting to cause friction between the races of the Commons, and possibly genocidal. Jijoan religious fanatics also cause friction and in some cases commit acts of destruction and violence, further complicating matters.

At the same time, elsewhere on Jijo, a young member of Hoon race named Alvin and his friends from several races receive unexpected help in their quest to make a bathysphere for underwater exploring. They are assisted by Uriel, a sage of the urrish race, who asks their help in locating a hidden underwater cache of galactic technology. The bathysphere fails while deep underwater, and the young crew is rescued by mysterious metal-clad beings. On the other end of "the Slope" a small group of humans attempts to quietly form a new settlement that may escape the murderous intent of the Rothen, but they find their Danik servants already there. A fight ensues and the group is scattered.

Back at the glade of gathering where the Commons of Jijo was in conflict with the Daniks, their differences suddenly become moot when a much larger starship lands directly atop the Rothen craft, imprisoning it in a quantum time-shifted substance. The huge battleship is revealed to be operated by the terrifying Jophur, the supremely egotistical and violent form of the peaceful and kind Trakei that live on Jijo.

Infinity's Shore
Alvin's group find themselves on a mysterious ship hidden deep in Jijo's seas. They are treated kindly but remain ignorant of who captured/rescued them from the depths. The reader, however, becomes aware they are aboard Streaker, the dolphin-crewed EarthClan ship not seen since the events of Startide Rising, some two years earlier in the series internal timeline. The crew is astonished to find all the different races living on Jijo, and the human commander, Gillian Baskin, is unsure what to do with the youngsters. She sends a dolphin raiding party to the mainland where both a Jophur and Danik support craft have crashed after fighting one another, and they return with Rety, a human child from a band of even more primitive humans leading a wretched existence outside the society of the Slope, and Dwer, chief scout of the Commons, who has a strained but genuine friendship with the young girl. They are accompanied by Mudfoot, known to Dwer as annoying "noor beast" but recognized by the Streaker crew as a Tytlal, a client race of the Tymbrini, Earthclan's closest and most loyal allies, notorious for elaborate pranks.

Back on the Slope, the Jophur commit terrible acts of war, they are especially enraged to find the G'kek race on Jijo, as they had engaged in a war of extermination against them and they were believed to be extinct. The Commons are secretly communicating with the Daniks aboard their now-submerged spacecraft, and are also constructing numerous new weapons and primitive technologies to improve their communication and defense capabilities. The Jophur remain ignorant of most of these efforts as they are simply unable to recognize them for what they are, but they do capture Lark Koolhan and Ling. The two of them manage to escape captivity and hide on the Jophur ship, which they learn is named Polkihjy.

Gillian Baskin decides to send the young friends into exile on a small island, for their own protection, but Alvin realizes at the last moment whose ship they have been on and demands to be allowed to stay. Contact is established between Streaker and Uriel the smith, and there is an exchange of personnel and equipment at Wuphon Port. Gillian is astounded to find her old crew mate Emerson, is the mysterious mute stranger who has been traveling with Sara Koolhan, they both join Streaker while much of her crew is left on Jijo. Streaker makes a bold escape attempt from Jijo using dozens of ancient derelict craft from the ocean bottom as decoys, as well as decoy balloons overseen by Dwer Koolhan. Polkihjy leaves Jijo to pursue Streaker, and Jijo's part in the tale ends with Nelo planning to rebuild his paper mill that was destroyed by religious fanatics.

As Streaker desperately flees towards the nearest hyperspace transfer point, Jijo's "Holy Egg" emits a powerful psychic blast that is felt by nearly everyone, and temporarily stuns the entire crew of the Jophur battleship.

Heaven's Reach

The final installment introduces a new character, Harry Harms, the first neochimp to be selected to serve as a scout for the Navigation Institute, and new setting, the bizarre realm of "E-level hyperspace".  Harry detects unusual activity and eventually encounters Rety and Dwer, who had an improbable reunion aboard one of the decoy ships and wandered into E-level hyperspace due to their total lack of knowledge of space technology. Harry brings them to Kazzkark, his home base, normally a sleepy outpost for galactic institutes but now teeming with refugees and the home of a strange new religion.

Streaker has received assistance and guidance from an unlikely ally, hydrogen-breathing life forms and machine lifeforms in their employ. The crew is dismayed to find that they have arrived back at the massive fractal world where they had been betrayed before by supposedly neutral members of the Retired Order. Old resentments seemingly rekindle and the fractal world erupts into fighting and chaos, resulting in millions of deaths and the collapse of the delicate structure of the world. Streaker narrowly evades another ambush and manages to escape in the chaos, still pursued by Polkihjy, which is barely under Jophur control as it has been invaded by hydrogen-breathing life forms. Lark, Ling, and the former Trakei sage Asx have all merged with one single gigantic life form now occupying much of the ship, which they simply call "Mother".

On Kazzkark, the youths from Wuphon Port, having been sent away because Gillian fears Streaker is on a suicide mission, arrive along with Kaa, the dolphin hotshot pilot. Alvin befriends local Hoons and he and Huck depart with them as they flee Kazzkark, which is becoming unstable. Ur-ronn meets starfaring urs and leaves with them. Pincer-Tip is killed by Ro-kenn, who was stowed away on their shuttle. Rety has become enamored of the new religious cult on Kazzkark and believes she is being held up as a leader of the movement, when in fact the cult plans to sacrifice her as a symbol of what they believe will be ultimately necessary, the sacrifice of Earth itself and all of EarthClan. Dwer and Harry, now joined by a Synthian trader, rescue Rety from the cult and barely escape Kazzkark as space tremors tear it apart. It is clear that a foretold "Time of Changes" is upon the civilization of the five galaxies, and momentous and often catastrophic events are occurring out on the space lanes. The group travel through E-Space, on what proves to be Harry's final mission for the Navigation Institute. Kaa, pushing his skills to the absolute limit, manages to get them back to Jijo's system just as all transfer threads in that entire galaxy collapse, meaning that galaxy is now cut off from the civilization of the five galaxies. They spot several other ships similarly stranded or destroyed, as well as a small rocket traveling from Jijo to a neighboring moon.

Streaker is forced to negotiate with members of the Transcendent Order, who wish to send them as emissaries to a distant galaxy. They convince the Transcendents, who send Polkihjy instead. Lark manages to briefly communicate with Streaker before they are cast into deep space, giving them several pieces of crucial information. Streaker finally arrives at the Earth system, which is heavily besieged by a massive space armada. They attempt to break through the lines by distracting the fleet with a strange, taunting holographic message. The tactic works better than imagined, frightening the fanatics into believing that they may have offended the Progenitors, and they give up the siege. Earth is free, for now.

Temptation

Temptation is a novella set in the immediate aftermath of Streaker's departure from Jijo, detailing the bizarre adventure of a small group of neodolphins left behind there.
