'''Io''' (also called '''Jupiter I''') is one of the four major moons of [[Jupiter]]. Io was one of four destinations that was Taken by [[the Witness]] at the end of [[Season of Arrivals]].

In the final days of the [[Golden Age]] the [[Traveler]] was in the midst of terraforming Io when it detected the [[Darkness]] approaching; The Traveler began to move to [[Earth]] in a defensive posture, leaving Io half-completed and flooded with the Traveler's formatted energies.<ref name="GF: Cayde-6">'''Bungie (2017/28/3)''', ''[[Destiny]]: [[Age of Triumph]] Playstation 4, Activision Blizzard, [[Grimoire]]: [[Grimoire:Allies/Legends_%26_Mysteries#Ghost_Fragment:_Cayde-6|Ghost Fragment: Cayde-6]]''</ref> As a result of this, the Ionian climate and geography do not support traditional agriculture, meaning that some remnant of Io's original atmospheric composition prevented the full growth of plants. The moon is still charged with the Traveler's pure energy, which lingers in the atmosphere of the moon, visible from orbit. <ref name="GF: Cayde-6"/> Echo Mesa, a mountain on Io,<ref>[https://www.wikiwand.com/en/List_of_mountains_on_Io#/List_of_named_Ionian_mountains '''Wikipedia''' - ''List of mountains on Io'']</ref> has become a popular pilgrimage site for [[Guardian]]s.<ref name="GF: Cayde-6"/> The Mesa overlooks a crater where the Traveler left behind a [[Cradle|mysterious city-like structure]].

The terrain of Io was covered in fossils, many of which closely resemble enlarged versions of ancient Earth organisms such as trilobites, ammonites and dinosaurs. It is unknown whether these fossils were a by-product of the Traveler's paracausal terraforming, or whether they pointed to some unrecorded history of transplantation between Earth and a more habitable Io in the distant past.

The Cabal [[Terrabase Charon]] featured banners and emblems of the [[Sand Eaters]] Legion, indicating that the Cabal may have had a presence on Io long before the [[Red War]].

During the Red War, Io became a warzone for [[Guardian]], [[Red Legion]], [[Vex]] and [[Taken]] forces. When the Red Legion arrived in the [[Sol System]] they set up at Terrabase Charon, on [[Echo Mesa]] and were met with resistance from the Vex and Taken forces there. Io was the final place that the [[Traveler]] influenced with [[Light]] in the Sol System, and as such is sacred ground to [[Warlocks]]. During the conflict, [[The Guardian]] traveled to Io on [[Zavala]]'s orders to find Ikora. After locating the Warlock Vanguard leader, Ikora sent the Guardian on several missions into a Cabal research base, ultimately revealing the Red Legion's plans for the Traveler and the Light. The Cabal were mining out the remaining Light energy from the Traveler, which attracted the forces of the Taken and forced the Cabal to evacuate. During the Guardian's time on Io, they also met [[Asher Mir]], an [[Awoken]] scientist who was fixated on the Vex, along with their activities on the planet.

 

A hidden [[Warmind]] vault, JYS-2, was buried beneath Io's surface and inadvertently uncovered by one of the Cabal's drills. An unidentified active AI - implied through various details to be [[Rasputin]] - was still using the facility. Instead, it communicated via pre-Golden Age music and philosophical quotations, which proved to intrigue the [[Vex]]. This was observed in the [[Adventure]] [[Arecibo]].

 

 

Several months after the arrival of the [[Black Fleet]], they caused the moon along with [[Titan (moon)|Titan]], [[Mercury]], and [[Mars]] to mysteriously disappear, just as the Traveler healed itself.
