Io, the innermost of Jupiter's Galilean moons, served as temporary base for Admiral Winfield's Exofleet remnant in the first years of the Neosapien War. It became a critical base after the destruction of the Resolute and much of Exofleet during the Third Battle of Earth.
During the Blockade of Io, the Neosapien fleet placed Io under seige due to the belief that Winfield had a functioning GRAF Shield. When Typhonus learned that the shield was non-operational, he ordered a full scale attack. However, the Pirate Clans came to Exofleet's aid and inflicted heavy losses on his fleet.
Combined with the losses he had suffered from the aftermath of the Battle of Sinope, Typhonus chose to retreat. This allowed Exofleet to escape to Chaos. Although Io was later captured by Typhonus, it was never mentioned again as a vital location.
