Rampart IV
GlacialFrozen outer world used for cold-weather combat training. The ice storms are natural. The live fire exercises are not.
Stumbled upon Rampart IV today—a glacial world locked in what must be perpetual winter, its surface a sprawling cathedral of water ice fractured by methane geysers that rise like pale ghosts against the starlight. The atmospheric readings are almost mundane (nitrogen, trace methane, the usual suspects for a frozen rock), yet there's something humbling about standing at the observation port watching those geysers exhale into the void, knowing they've been doing this since before my grandparents were born. If the survey drones confirm what I suspect about subsurface liquid reserves, this could be more than just another ice ball—but first, I'll need to thaw out my instruments and my nerves.
