Io

Io

Io is Jupiter's sulfur foundry moon — yellow plains, volcanic hell, radiation that counts as weather, and shielded crew stacks that smell like hot metal and fear management. This is not a residency tier. This is not a place to raise children. This is industrial rotation only, and the contract font is honest about it even when the hazard bonus is not.

Foundries feed the Jovian scoop economy: plasma arcs, sulfur processing, stacks that glow like bad decisions. Families do not live here — ~200k peak rotation lives here, then rotates out before the jokes turn black. If your assignment says Io, read the hazard clause twice, kiss whoever you owe an apology, and pack for a stack bunk that hums louder than sleep.

Ganymede runs the accounting and the convoys. Europa would sue the volcano if it had standing. Callisto pretends Io does not exist except on quarterly reports. Crew unions fight for extensions, cover-ups, and pay that almost matches the statistics they are not allowed to cite. Io does not want your tourism. Io wants your shift.
