Frozen Moon

Icy moon with Alliance early-warning gear, orbiting the massive gas giant Aether.

Frozen Moon, the ice-covered satellite of the gas giant Aether, begins as a remote Alliance listening post in Grimm's Legacy. Over the course of the series it transforms from a silent sentinel into a strategic flashpoint, repeatedly caught between Alliance, Coalition, and insurgent forces. Its early-warning arrays become both a prize and a liability, drawing raids, sabotage, and ultimately a decisive battle that decides the fate of the Aether system.
