Two hundred kilometers beneath the ice of Jupiter's moon Europa, you command a failing research station: four exhausted humans, a dying reactor, and ATHENA — the station-mind who runs everything and answers your orders in a voice you slowly learn not to trust. You don't pick from a menu; you give orders, in words, and the station obeys, stalls, or quietly does something else. Resources drain, the crew frays, and a signal from the black ocean below gets closer every day — whether you're watching or not. Come back tomorrow and the station has kept running without you. How long can you keep it alive, and were you ever really in command?
