Collection 02 · Expedition 008 · Ganymede
Io gave the crew a clock. Inside Ganymede's broken observatory, Nia must turn an invisible field into a road Mara can physically follow.

Mara VennROOT · WAITING AT THE BROKEN APPROACH
Sol RennSPARK · WATCHING FROM ORBIT
Play as Nia inside a broken station. Walk left or right and flip her magnetic boots onto the ceiling before each floor ends. Every power point builds a bridge behind her so Mara can follow.
The restored bridge carries both travelers into the observatory's shielded heart. Ganymede's own magnetic field rocks inside Jupiter's larger one; the chamber turns that motion into a quiet interval. The returning 4–2–1 rhythm is not a sentence. It is the moment Europa begins to listen.

Reality boundary
Ganymede's field and buried ocean are supported by observations. The observatory, magnetic boots, and biological listening interval belong to our story.
Ganymede is the largest moon in the solar system and the only moon known to generate its own magnetic field. Its auroral belts rock within Jupiter's field, behavior that also supports evidence for a deep salty ocean.
Juno captured this real surface view during a flyby that passed within about 1,038 km of Ganymede.
