Io

The innermost Galilean moon, a volcanic sulfur hell terraformed into the Rim's breadbasket—where Darrow meets the Moon Lords.

Story so far

Io is the innermost and smallest of Jupiter's four great moons, a driest-in-the-system hell of sulfur dunes, volcanoes, and magma lakes under Jupiter's marbled, radiation-spewing face. The Society Engineering Corps blanketed millions of acres with pulseFields, hauled in dirt and water, and tapped the moon's tidal heat to make it the greatest breadbasket between Mars and Uranus—all on lowColor labor. Its hardy, low-gravity Golds hold themselves the truest heirs of the Iron Golds.

When Revus au Raa's heirs seized the Calisto garrison fleet and declared Io's independence, they ignited the Second Moon Rebellion. Here, on the edge of its 120-degree Sulfur Sea, Darrow, Sevro, and Sefi meet Vela au Raa, and Darrow is taken to Romulus's modest volcano-shadowed home to bargain for the Rim's fleet.

Appearance

A canvas of yellow and orange sulfur plains and dunes broken by volcanoes, magma lakes, sheer thrust-fault cliffs, and concentric green pulseField farms, all beneath Jupiter's vast marbled disc.

Role
