Io Overview

A partially terraformed planetoid orbiting Jupiter, Io was abandoned by the Traveler, though Ikora Rey and the Warlock Guardians consider the area around the Echo Mesa mountain to be sacred. Currently, this region has seen recent Cabal activity, though the Red Legion appear to be actively fleeing the world, rather than savaging it. The reason may involve some concerning anomalies detected by Asher Mir. Although this area has examples of impressive Vex architecture, the telltale signs of Taken activity are present throughout this place.
