The contract was straightforward. The microcredit transfer was confirmed. The task: investigate the silence at Eidolon Station, a secret Sinoex research facility drifting in the belt. Recover the proprietary data logs, secure the experimental assets, and restore the link. It sounded like a clean extraction for a team of veteran scrappers.

But Eidolon isn't just a station. It's a biological accident. Deep in the station's core, an experiment in high-energy physics has torn a hole in reality, and an exotic biomass is leaking through the fold — a quasi-sentient mutagen that triggers runaway mitosis and incorporates every living thing it touches. The airlocks are malfunctioning, the reactors are redlining, and the team is trapped in a derelict asteroid habitat with bio-engineered predators that haven't been fed in a week.
