Io

Io (also called Jupiter I) is one the four major moons of Jupiter.

Overview
In the final days of the Golden Age the Traveler was in the midst of terraforming Io when it detected the Darkness approaching; abandoning the moon it fled to Earth. As a result of this the Ioian climate and geography do not support traditional agriculture, meaning some remnant of Io's original atmospheric composition prevented the growth of plants. Echo Mesa, a mountain on Io, has become a popular pilgrimage site for Guardians.

One of the legends of the Nine state they are some of the original Awoken transcended to mental form and live inside the Jupiter-Io.
