A former soldier inside a pressurized dome on Keth-9 is taken for processing and tries to escape through the under-ice infrastructure. Security units and off-world operators hunt him while the colony itself begins to turn unstable under his actions.

He moves deeper into confined tunnels, using the systems around him instead of running, forcing pressure and flow where they were never meant to go. The structure starts failing in stages, air, heat, and stability slipping as the environment itself becomes part of the conflict.

What begins as an escape attempt shifts when the damage spreads beyond control...
