"Lush with giant twisted trees, deep caverns, waterfalls, and silver swamps, the origin of this planetoid remains unknown. What is clear is that the Vex have nearly transformed the entire planetoid into a Machine World, above and below the surface. For those Guardians willing to brave the dangers and explore the myriad of mysteries, treasures beyond the imagination await."

— Website description ^[2]

7066 Nessus is a Centaur minor planet with an irregular orbit. At perihelion, Nessus is closer to the Sun than Uranus; at aphelion, Nessus moves into the Kuiper belt.

History

Golden Age

During the Golden Age, the Colony ship Exodus Black crashed on Nessus on its way to Kepler-186. It's crash was due to the result of the Orbiting Centaur's added six dimensions to it's four dimensional. They were all lost in their sense of Time, past and future went hand and hand for them.Exodus Down All of its colonists and crew were subsequently either captured and experimented on (such as stealing the memories of the captain) or killed by the Vex. Unable to contact help, the ship's AI, Failsafe, became dormant until she was awoken by the arrival of Cayde-6.

City Age

Approximately 126 years before the SIVA Crisis, Nessus re-entered the Solar System after an unexpected delay. The Arcadian Valley patrol space is scattered with the remains of the Exodus Black, picked clean by Fallen scavengers. ^[3] At some point, the Vex, overseen by the Axis Mind Argos, Planetary Core, fully converted Nessus into a Machine World.

The Axis Minds of Nessus are noted to have higher than average computational power. One such mind imprisoned Failsafe for attempting to access the Vex Network. Sagira sought out another such Mind in order to analyze a map of the Infinite Forest.

Red War

Following the Red Legion's invasion of Earth, they began to mobilize their forces across Nessus in an attempt to uncover any secrets it harbored. During this mobilization they came into conflict with the local Vex population^[4] as well as the Fallen House of Dusk which was scavenging whatever they could from the remnants of the Exodus Black.^[5]

Following the death of Dominus Ghaul, Calus' flagship, The Leviathan, arrived at the Solar System and began to consume sections of the planetoid. ^[6]. Doing so caused Argos to be sucked into the Leviathan's vacuum alongside a squadron of Vex, forcing Calus to call upon the Guardians to be rid of the Vex Mind for good. Succeeding in destroying the Axis Mind, the conversion of the planetoid has been permanently halted but the Leviathan continues to slowly consume Nessus into Royal Wine.

Trivia

In an early development The Myriad was a working title for Nessus.
- This makes sense, as Nessus could be described as a myriad in many manners. It contains mixtures of Fallen, Vex, and Cabal technologies, and is strongly influenced by all of those species. It is covered in mixtures of Fallen scavenges, Vex ruins and strange constructs, scattered bits of the Exodus Black, Cabal drills and structures, etc.
The Vex who reside on the planet bear slight technological and physical differences from those across the rest of the Solar System.
Large parts of Failsafe's ship, the Exodus Black, can be found along parts of Nessus. Scannables in the area indicate that Failsafe's crew tried to escape and survive, but died due to a lack of food and supplies.
- Failsafe's crew do refer to the presence of the Vex, suggesting that the cyborgs were present when they arrived. Failsafe referred to the fact that she had been on Nessus long enough to see the Vex take over the entire planet, convert approximately 92% of it into a machine world like Mercury, and kill all life forms.
- Armor and various lore pieces from Nessus have even suggested that the original crew of the Exodus Black was headed for Kepler 186f, a habitable planet very far from the Solar System. Some unknown force (possibly Vex technology) caused the ship to lose control and veer towards Nessus, which was near it's path at the time. The engines and some parts of the ship malfunctioned, resulting in a crash landing. That was when the crew of the Exodus Black would face the Vex and meet their ends.
Some birds and small animals can be seen flying over and around areas on Nessus. Plant life also exists there. It is unknown whether Nessus actually held life before the arrival of the Vex. Neither Ghost nor the other Vanguard members suggest that the Traveler terraformed it, however, some scannables evidence that the life on Nessus is artificial, being created by the Vex for unknown purposes.
Nessus could possibly be the farthest location the Guardians have traveled to in the Destiny series.
